CONNECTIONS TO BE MADE

Into the vehicle

With the key in the off position:

Connect the Black wire of the AXSWC-TL to the ground.
Connect the (2) Red wires of the AXSWC-TL to accessory power.
For all vehicles EXCEPT the Lexus SC430, connect ONLY the 12-pin connector to the mating connector in the vehicle. The 6-pin connector on the AXSWC-TL harness WILL NOT be used in the application.
For the 2002-2005 Lexus SC430, connect ONLY the 6-pin connector to the mating connector in the vehicle. The 12-pin connector on the AXSWC-TL harness WILL NOT be used in the application.
Note: Disregard the 12-pin connector in the vehicle.
For the 2006-2009 Lexus SC430, connect BOTH the 6-pin and 12-pin connectors to the mating connectors in the vehicle.

To the radio

For the radios below, connect the included female 3.5mm connector with the Brown and Brown/White wires into the male 3.5mm connector of the AXSWC-TL harness.
- For Eclipse radios: Connect the Eclipse steering wheel control wires (normally Brown and Brown/Black) to the Brown and Brown/White wires of the AXSWC-TL. Brown of the AXSWC-TL goes to the Brown/Black of the Eclipse and Brown/White of the AXSWC-TL goes to the Brown of the Eclipse.
- For Metra OE: Connect the SWC Key 1 wire (Gray) to the Brown wire of the AXSWC-TL. Isolate and tape the Brown/White wire, it will not be used.
- For Kenwood or select JVCs with a Blue/Yellow steering wheel control wire: Connect the Kenwood/JVC steering wheel control wire to the Brown wire of the AXSWC-TL. Isolate and tape the Brown/White wire, it will not be used.
  Note: Some of the newer Kenwood radios will auto-detect as a JVC. If this is the case, use a 12k ohm resistor inline between the Blue/Yellow and Brown wire of the female 3.5mm jack during programming only (remove the resistor once programmed).
For Parrot Asteroid Smart or Tablet: Connect the AXSWC-TL male 3.5mm jack into the AXSWCH-PAR (sold separately) female 3.5mm jack and plug the 4-pin end into the corresponding SWC plug on the radio.
Note: AXSWCH-PAR is required (sold separately) and the radio MUST BE updated to rev 2.1.4 or higher.
For XITE radios: Connect the steering wheel control SWC-2 wire from the radio to the Brown wire of the AXSWC-TL.
For all other radios: Connect the 3.5mm jack of the AXSWC-TL into the jack on the aftermarket radio designated for an external steering wheel control interface. Please refer to the aftermarket radios manual if in doubt as to where the 3.5mm jack goes.

PROGRAMMING

The AXSWC-TL will auto-program itself through Auto Detect Mode.

Turn the ignition on and wait until the L.E.D. in the AXSWC-TL lights up solid (about twenty seconds).
Note: Do not press any buttons on the steering wheel or radio during this time.
Once solid, cycle the key off, then back on.
Note: The AXSWC-TL will give you two sets of L.E.D. feedback reports. The first set of flashing green L.E.D. lights is for knowing the vehicle type and the second set of red flashing
L. E.D. lights are for knowing the radio type. Knowing the vehicle type is irrelevant as this interface is pre-programmed for vehicles in the application list only. However, knowing the radio type is important for troubleshooting if the AXSWC-TL does not work. Please see the below Radio Legend for L.E.D. feedback information for radio type.

Note: If the AXSWC flashes 7 times and you do not have an Alpine radio connected to it that means that the AXSWC did not see any radio connected. Verify the 3.5mm connector is connected to the steering wheel control input into the radio.
Note: The AXSWCH-PAR is required (sold separately). The radio must be updated to rev. 2.1.4 or higher from www.parrot.com and AXSWC must be updated to the latest firmware from www.axxessinterfaces.com.

TROUBLESHOOTING

Confirm that the 3.5mm connector is connected to your radio securely and in the correct location.
If using the female 3.5mm connector in Eclipse, Kenwood, select JVC, or Metra OE radios, and verify that the radio’s steering wheel control wire is connected to the correct wire to the AXSWC-TL.
Note: Not every radio will have all the possible SWC commands on the steering wheel. Please refer to the radio owner’s manual or contact the radio vendor for specific commands that the radio will recognize.o

EXTRA FEATURES

The Axxess Updater App must be used to program the following:

Changing radio type
If the L.E.D. flashes do not match the radio you have connected, you must manually program the AXSWC-TL to tell it what radio it is connected to.

Remapping the steering wheel control buttons
If you have AXSWC-TL programmed and you want to change the button assignment for the steering wheel controls.

Note: Volume Up and Volume Down cannot be remapped.

RESETTING THE AXSWC-TL

Turn the ignition on, and wait three seconds.
Press the reset button for three seconds, then let go.
Once flashing fast, wait until the L.E.D. in the AXSWC-TL lights up solid (about twenty seconds). Note: • Do not press any buttons on the steering wheel or radio during this time.
- If the AXSWC-TL does not flash fast the Reset button was not depressed properly.
Once solid, the AXSWC-TL is reset and should be working with default settings. i
