CAN Communication System

DIAGNOSTIC TROUBLE CODE CHART

1. DTC TABLE BY ECU

HINT:
- In the CAN communication system, CAN communication system DTCs can be displayed by the ECU using the hand-held tester.
- If CAN communication system DTCs are output, trouble cannot be determined only by the DTCs. Perform troubleshooting according to "HOW TO PROCEED WITH TROUBLE SHOOTING". (If, however, U0235 or U1102 is output alone, check the dynamic laser cruise control system.)

U0001-U1102:

a. ECM

HINT:
- DTC communication uses the CAN communication system.
- Cruise control ECU data is also output.

U0073-U0126:

b. SKID CONTROL ECU

HINT: DTC communication uses the SIL line.

c. NETWORK GATEWAY ECU

HINT: The gateway ECU is connected to the CAN communication system but CAN communication system DTCs are not output.
