PROBLEM SYMPTOMS TABLEProblem Symptoms Table:
1. COMMUNICATION STOP MODE TABLE
a. Check that there is no open circuit in the CAN main bus line, short between the lines, or short to +B in the "CHECK CAN BUS LINE". Select "BUS CHECK" on the hand-held tester via the CAN VIM.
b. Check the communication stop mode of the ECUs or sensors not displayed among the following: "ENGINE", "ABS/VSC/TRAC", "STEERING SENSOR", "YAW/DECELERAT", "EPS", "BODY/GATEWAY", "HYBRID CONTROL" OR "HV BATTERY".
NOTE:
- Systems using the CAN communication system differ according to optional settings. Check which ECUs or sensors are installed on the vehicle.
- Non-installed ECUs or sensors are not displayed. Be careful not to consider that they are in communication stop mode.
- If 2 or more ECUs or sensors are not displayed on the hand-held tester via the CAN VIM, perform troubleshooting for communication stop mode for each undisplayed ECU or sensor. (Either side of the CAN bus lines may be open.)
2. DTC COMBINATION TABLE
a. Perform troubleshooting according to the combination of DTCs output.
NOTE:
- If U0146 or P3108-594 is output, check the "MULTIPLEX COMMUNICATION SYSTEM" before proceeding to "GATEWAY ECU COMMUNICATION STOP MODE".
- If U0100-211 or U0111-208 is output separately by the hybrid control ECU, refer to "HYBRID CONTROL SYSTEM".
