INTERMOTIVE G-ILISC517-AD Shift Interlock Lift Door

Introduction

The G-ILISC517-AD is a microprocessor driven system for controlling wheelchair lift operation. The default system can operate with the vehicle ignition on or off. Lift operation will be enabled when specific vehicle safety conditions are met and the vehicle will not be able to operate when the wheelchair lift is in use. Optional Plug and Play harnesses are available for most applications, making installation fast and easy. “Key OFF Only” operation is available with instruction sets to change operating modes.

IMPORTANT—READ BEFORE INSTALLATION

It is the installer’s responsibility to route and secure all wiring harnesses where they cannot be damaged by sharp objects, mechanical moving parts and high heat sources. Failure to do so could result in damage to the system or vehicle and create possible safety concerns for the operator and passengers.
Avoid placing the module where it could encounter strong magnetic fields from high current cabling connected to motors, solenoids, etc. Avoid radio frequency energy from antennas or inverters next to the module. Avoid high voltage spikes in vehicle wiring by always using diode clamped relays when installing up fitter circuits.

Installation Instructions

Disconnect vehicle battery before proceeding with installation.

WARNING
Disconnect the battery to prevent setting a check engine light.

CAUTION

All electronic products are susceptible to damage from Electrostatic Discharge or ESD. Ground yourself before handling or working with the module and harnessing by first touching chassis ground, such as the barrel of the cigarette lighter.

G-ILISC517-AD Module

Locate the module in an area away from any high heat sources (engine heat, heater ducts, etc.) preferably behind the glove compartment. Do not actually mount the module until all wire harnesses are routed and secure. The last step of the installation is to mount the module.

Gateway Plug and Play Harness (4-pin connector)

Locate the vehicles Gateway Module. It will be mounted behind the glove compartment.
Press the tabs inward on the sides of the glove compartment and fully lower it.
Remove the 3 nuts securing the Gateway module to the vehicle.
Remove the 26-pin connector from the side of the Gateway module and plug into the mating connector on the G-ILISC517 harness.
Plug the male 26-pin connector from the G-ILISC517 harness into the Gateway module.
Reinstall the Gateway module and the glove compartment.
Plug the free end of the Data Link harness into the mating 4-pin connector on the G-ILISC517-AD module.

LED Display Panel Mounting – Black 4-pin connector

Locate a suitable position on the dashboard, within view of the driver to mount the LED Display Panel. Ensure there is open space behind the dash where the panel is mounted. The harness is 40” in length, which is the maximum distance the display can be from the module.

Drill a 5/8” hole in the dash where the center of the display will be located.
Attach the Black 4-pin connector of the LED display panel harness to the module.
Run the other end of the harness under the dash and out through the 5/8” hole.
Attach the end to the LED Display Panel.
Ensure the panel is level and secure using supplied screws.

Ford Transit Ignition Switch (Shift Lock)

Remove the lower dash trim panel.
Remove the lower steering column trim cover.
Locate the ignition switch connector (C250) and disconnect it from the ignition switch.
Install the G-ILISC517 harness between the Ignition Switch and the OEM connector.

Connecting a Lift Door Input (Cutaway Vehicle or Key Off Mode)

Installing discrete lift door input is only necessary to operate the module in “Key Off Only” mode, “Key On and Off” mode or if the vehicle does not have OEM door switches. If you are working on a vehicle that has no door switch installed (cutaway chassis), a door switch (on the (lift) door) must be installed. The module’s pin 8 (gray wire) of the 8-pin connector (see the appropriate CAD drawing) must be connected to the door switch. NOTE: this input must provide a ground level value when the door is open (Low-True). The next section assumes the vehicle has preinstalled OEM door switches and explains how to make the discrete connection for the side door.

After installation, refer to “Discrete Door Input Mode” of instructions for lift door selection procedure.

The module’s default setting reads door status over vehicle communication network and operates in “Key On Only” mode. If operating in “Key On Only” mode with OEM doors, a discrete input is not needed.

OEM Side Door Discrete Connection

If “Key OFF” operation is desired, a discrete Lift Door input must be made to the module. This is accomplished by connecting into the existing vehicle switch harness above and behind the driver’s seat.

The slide door wire (yellow) is in this harness. Unscrew the Gray cap on the included Posi-Tap connector and install it on the appropriate wire, then screw the rest of the connector onto the cap snugging it down but not overly tight.

Unscrew the other end of the Posi-Tap connector, strip 1/4” insulation off the Gray wire coming from pin 8 of the module, and insert it through the loose piece so the wire end is even with the piece edge. Hold the wire so it doesn’t push back out of the Posi-tap, and screw it back into the main Posi-Tap body. Holding the main Posi-Tap body, gently pull on the just-installed wire to make sure it is solidly connected. Secure the connection using tape.
NOTE: there is an additional sequence that must be run at installation which identifies the lift door to the module.

Control Inputs/Outputs – 8-pin connector

The G-ILISC517-AD provides a ground side input and one 12V, 8 amp output.
Refer to the G-ILISC517-AD CAD drawing as reference when reading these instructions.
Lengthen the following wires appropriately, using solder and heat shrink tubing or tape.
The blunt-cut harness provides for control connections to the vehicle as follows:

Pin 1 – Blue Wire – Shift Lock Request (+12V)

Pin 3 – Orange – This Lift Enable/Vehicle Secure output provides 12V@8 Amps when it is safe to operate the lift. Connect this output to the lift’s “enable” signal.

BRAUN
RICON
**Mobility Networks/VMI

**

Drawings are looking into the backside of the connectors where the wires exit the connector.

Note: connecting the Lift Enable/Vehicle Secure Orange wire to the wrong lift pin can damage the interlock.

If in doubt, try connecting a fused (8A) source 12V signal to the pin in question to ensure it enables the lift and does not draw too much current, such as when connecting to a ground pin. If the lift draws more then 8 amps on it’s enable signal, a control relay will need to be installed.

Pin 4 – Green Wire – Auxiliary door input (Ground signal when a door is open)

A Green wire is included with the panel. Insert one end of the Green wire into Pin #4 of the G-ILISC517 8 pin connector. Attach the other end of the Green wire to the door switch wire/s that provides a ground when the chosen door is open.

For non-OEM door condition
Disables CAN Aux door detection when used
Must have diode protection in the case of multiple Aux doors connected

Pin 6 and 7 – Shift lock Output.

Pin 8 – Gray Wire – This input must “tap in” to the existing Lift Door switch wire or connect directly to an installed door switch. This can be used to detect door open/close.

Connect the 8 pin connector to the module

Lift Door Identification

*OEM rear door only available with “Key On” operation. If “Key Off Operation” is desired on the rear door, a door switch must be installed. Refer to page 3 for discrete install instructions.

The module’s default settings have the lift door as the rear door and door status on the vehicle communication network. If the vehicle has the OEM side and rear doors with built in switches, the module needs to know which of the two possible doors (side or rear) is defined to be the lift door. The following procedure must be performed in order to accomplish this:

Vehicles with OEM Side Door

Assure side and rear doors are completely closed.
Vehicle is in PARK with key in the RUN position and engine OFF.
Park brake is applied.
Put the module in diagnostic mode by pressing the Red “Test” button on the module – the module LEDs will scroll, then LED1 will “blink out” the firmware version, and finally LEDs 1 – 3 (at minimum) will come ON steady.
Wait for LED1 to complete “blink out” the firmware version and all LEDs become steady.
Pump the Service Brake pedal 4 times within 5 seconds until you see module LEDs 1 – 4 blinking together.
Open the lift door; The module LEDs will stop blinking and remain OFF.
Verify the lift door is “known” by opening and closing it while watching the “Lift Door Open” LED on the display panel. If there is no indication or if the sense seems opposite to what it should be, the previous sequence must be repeated.

Discrete Door Input Mode

Assure Side and Rear Doors are completely closed.
Vehicle is in PARK with Key in the RUN position, either the driver or passenger door must be open, the engine is OFF, and the Gray wire on the 8-pin connector is not grounded and/or the lift door is closed.
Put the module in diagnostic mode by pressing the Red “Test” button on the module – the module LEDs will scroll, then LED1 will “blink out” the firmware version, and LEDs 1 – 3 (at the least) will come on steady.
Depress and continue to hold the Service Brake while doing steps 5 through 6.
Press the Red “Test” button a second time on the module – the Status LED, LED1, and LED2 will blink On and Off slowly.
Jump a ground to the Gray wire on the 8-pin connector or have a second person open the Lift Door that the Gray wire is attached to.
LEDs 1 – 4 will blink rapidly, if successful.

NOTE: For discrete door, ensure the discrete wire has been installed before performing pat and rub above (refer to above)

KEY OFF ONLY mode

The module’s default setting is “Key On Only” operation. Vehicle secure only turn on when all conditions are met. NOTE: in “Key On Only” mode, the module will go to sleep in 15 seconds after the vehicle is turned off with the key in off position. To change operation mode to “Key Off Only” mode, the following procedure must be performed:

Assure Park Brake is NOT applied with Key in RUN position and engine OFF.
Put the module in diagnostic mode by pressing the Red button on the module.
Wait for module’s LED1 to finish “blink out” firmware version and all LEDs become steady.
Hold the Red button down on the module again while holding down the Service Brake.
Continue holding Service Brake until LED3 and LED4 turn on steady and let go of Service Brake while LED3 and LED4 is still ON.

NOTE: Releasing the Service Brake while LED3 and LED4 is still ON sets the module to “Key Off Only” mode. Whereas releasing the Service Brake while LED3 and LED4 is OFF sets the module to “Key On” mode. “Key Off Only” mode will only work if discrete Lift Door input connection is installed.

Post Installation / Check List

G-ILISC517-AD (Manual Lift Door)

The following checks must be made after installation of the system to ensure correct and safe operation of the lift. If any of the checks do not pass, do not deliver the vehicle. Recheck all connections as per the installation instructions.

Begin the checklist with the vehicle in the following state:

Lift stowed
Lift Door closed
Park Brake set (PB)
Transmission in Park (P)
Ignition off (Key off). Wait until the module goes into “Sleep” mode (all panel LEDs OFF) which takes approximately 5 minutes.

KEY ON CHECK: NOTE—you can skip this section if module set up for Key OFF Only

Turn ignition key on (to “Run”), verify the module wakes up and all 5 LEDs turn ON for approximately 2 seconds. The lower icon LEDs are backlit and should remain ON whenever the module is awake.
Verify that the Park, Park Brake, and the Shift Lock LED remain ON.
Attempt to deploy the lift. The lift must not deploy with the Lift Door closed. Next, open the lift door.
With Lift Door open, Park Brake set and transmission in Park, all 5 LEDs will be ON. Attempt to deploy the lift. Verify the lift deploys. Stow the lift.
With Lift Door open and transmission in Park, release Park Brake. Verify that the Park Brake (PB) and Vehicle Secure LEDs turn OFF, and attempt to deploy the lift. Verify the lift does not deploy.
With Lift Door closed and Park Brake set, verify transmission will not shift out of Park.
With Lift Door open and Park Brake released, verify transmission will not shift out of Park.
With Lift Door closed, Park Brake released and Service Brake applied, verify you can shift out of Park.

KEY OFF CHECK:

Start with the same conditions as for KEY ON check above except do not wait for the module to go to sleep. The key remains OFF throughout this test.
Repeat Steps 2 – 5 (above) to complete this test.
Close the Lift Door and verify module goes to sleep after 5 min.
Open the Lift Door and verify module wakes up with display LEDs proving out; Then Park, Shift Lock, and Lift Door Open LEDs remain ON.

Using Module LEDs

The module has 5 on-board LEDs which are used to convey information about the operation of the module. In the normal mode all LEDs are OFF, but they come ON in different situations:

Operation Errors

Under certain conditions the module LEDs are used to indicate errors which prevent continued operation. In this case, the Status LED will blink and depending on which other LEDs are lit, the error is identified as follows:

LED1 ON – Set-up error on output device.
LED2 ON – Could not set up the CAN communication
LED3 ON – Output error
LED 2 &3 ON – Loss of CAN traffic

VIN Errors – If there is an error while getting the vehicle VIN during initial installation, LEDs 1-4 will scroll 2 times then another LED will turn on to ID the error as follows:

LED1 ON – Wrong Manufacture (Not Ford)
LED2 ON – Wrong chassis (Not a Transit)
LED3 ON – Wrong engine
LED4 ON – Wrong model year
STATUS ON – Bogus VIN (e.g. all characters the same)
No LEDs ON – No VIN response

Status – One can put the module into a diagnostic mode where each LED represents a system status. The module is fully functional in this mode. To enter diagnostic mode, press the Red button on the module. LEDs will scroll a couple times, LED1 will “blink out” the current firmware version, and then the LEDs will reveal system status as follows:

LED 1 ON when Shift Lock enabled.
LED 2 ON when transmission is in park.
LED 3 ON when Park Brake is set.
LED 4 ON when Lift Door is open.
STATUS LED ON indicates “Vehicle Secure” or “Lift enabled” meaning there is 12V on Pin 3 (Orange wire) which connects to the lift.
Cycling the key will exit Diagnostic Mode and all LEDs will be off.

G-ILISC517-AD (Manual Lift Door)

The G-ILISC517-AD is a microprocessor driven system for controlling wheelchair lift operation. The system will operate with the vehicle ignition ON or OFF, (if optional Park Brake and Lift Door input supplied) or if so set up, the lift will only be energized if the Key is OFF. Lift operation is enabled when specific vehicle safety conditions are met and will lock the transmission in Park when the wheelchair lift is in use. The G-ILISC517-AD prevents the vehicle from being shifted out of park if the lift door is open. As an added feature, the vehicle cannot be shifted out of park anytime the parking brake is applied. This eliminates excessive Parking Brake wear due to driving with the parking brake applied.

Key On function:

When the vehicle is in “Park” the (P) LED will be ON.
When the Park Brake is applied, the (PB) LED will be ON.
When the Lift Door is open, the Door Ajar LED will be ON.
With the vehicle in Park and either the Park Brake applied or Lift Door open or external Shift Lock input enabled, the Shift Lock LED will be ON, and the transmission cannot be shifted out of Park.
With the vehicle in Park, Park Brake applied and Lift Door open, the Vehicle Secure LED will be ON, and the lift will be operational. All LEDs will be illuminated on either display panel.

Key Off function: (if discrete Park Brake and Lift Door input supplied)

Vehicle must be in Park before turning key off.
With the vehicle in Park, the (P) LED and Shift Lock LED will be ON.
With the Park Brake applied and the Lift Door open, all LEDs will be ON, and the lift will be operational.

Sleep Mode: When the lift door is closed and ignition power (Key) is turned OFF, the vehicle CAN communication traffic will stop after a delay. Around five minutes after this, the system will enter a low current “sleep” mode of operation with all LEDs OFF. To wake from “sleep” mode, turn the ignition on (key on) or open the lift door.
All display LEDs will turn ON for approximately 2 seconds as a “prove out”. The backlit LEDs remain ON as long as the module is awake.

If the G-ILISC517-AD fails any step in the Post Installation Test, review the installation instructions and check all connections. If necessary, call Inter Motive Technical Support at 530-823-1048.
