Overall Dimensions

Output interface of CANCrocoLITE
CANCrocoLITE output interface — CAN 2.0B, according to international standard SAE J1939.

Unit structure and operation principle of CANCrocoLITE

• The principle of CANCrocoLITE operation is based on reading the electromagnetic field that is formed around the wires during the signal passing.
• CANCrocoLITE forms digital output signals that contain data packages identical to the signal of the connected CAN bus. This signal can contain information about the operating modes of the engine, fuel consumption, sensor status, and malfunctioning of the Vehicle.

Connection of CANCrocoLITE

ATTENTION:
Strictly follow safety rules of automobile repair works as well as local safety rules of the customer company when mounting CANCrocoLITE. Before CANCrocoLITE installation it is recommended to study carefully the electrical circuit diagram and the Operating Manual of the vehicle on which CANCrocoLITE is mounted.

Exterior inspection before connection

• It is required to conduct CANCrocoLITE exterior inspection for the presence of possible defects of body or connectors arising during transportation, storage or careless use.
• Contact the supplier if any defects are detected.

Recommendations for the search of CAN bus wires

• To connect CANCrocoLITE to the on-board CAN bus, you should find and identify CAN-H (CAN HIGH) and CAN-L (CAN LOW) wires.
• Physically, the CAN bus most often represents a twisted (stranded) pair of wires (30 windings per running meter) with splitters to connect electronic control units (further on – ECU) that have terminating resistors of 120 Ohms nominal impedance located at the ends of the bus. The resistors may be mounted separately or may be integrated into the ECU. As a rule, there is no SHLD wire.

Example:
DEUTSCH company manufactures CAN buses made of special three-conductor cable (CAN-H, CAN-L, and signal GND) with 7 to 12 mm external coating diameter, special splitters, and terminating elements – terminating resistors designed to match wave impedance during the transmission of messages in the bus and to suppress interference (see figure 9).

• There may be from one to six and more CAN buses on the vehicle of EURO-3 Environmental Standard. They may be defined as M-CAN, T-CAN, I-CAN, H-CAN, A-CAN, EBS-CAN etc.
• The following three CAN buses are of interest for fuel consumption monitoring: T-CAN, M-CAN, and I-CAN (seldom).

T-CAN and M-CAN may have the following features:

• Availability of OBD II connector for diagnostics (see figure 10);
• the color and cross-section of stranded pairs of wires;
• connection of stranded pairs of wires to contacts at OBD II and ECU connectors.

Example:
If there is an OBD II diagnostics connector on the vehicle and a pair of stranded wires of orange colour one of which has a black band, and the other has a brown one, and this pair of stranded wires matches the OBD II diagnostics connector, so this may be the CAN bus you are looking for. In this case, the orange wire with the black band is CAN-H, while the wire with the brown band is CAN-L.

Contacts of the ABS/ASR ECU system corresponding to the CAN bus are identified according to Figure 11.

WARNING:
Features of CAN bus may be different for different vehicle manufacturers. Besides, those features may be different for the same manufacturer depending on the design features of the vehicle and its configuration (the engine, fuel supply system, the link between the engine EDC and the throttle pedal, availability or absence of the electronic dashboard, digital tachograph, etc).

Initial diagnostics and assessment of CAN bus serviceability may be carried out using a multimeter by means of the following traditional methods:

• continuity test of CAN-L and CAN-H wires;
• short circuit and impedance check (full impedance depending on the terminating resistors and input impedance of ECUs connected to the bus) between CAN-L and CAN-H wires;
• measurement of voltages in CAN-L and CAN-H wires in the recessive mode (the ignition is off, the battery disconnect switch is on) and in the dominant mode (the ignition is on and the engine has been started).

The impedance check should be carried out with the whole onboard circuit off (the battery disconnect switch is off). The control impedance value must be no more than 60 Ohms.

The serviceability check of the CAN bus is carried out with the ignition and engine on, by pressing and releasing the throttle pedal between the wires of the stranded pair of wires. The control voltage value must be from 1.2 to 3.0 V.

CAN-H and CAN-L can be identified according to the following voltage values:

• recession mode — about 2.5 V (on both CAN-L and CAN-H);
• dominant mode — less than 2.5 V (on CAN-L) and more than 2.5 V (on CAN-H).

Examples of oscilloscope pictures of signals from CAN-high and CAN-low are presented in Figure 12.
