Problem Symptoms Table

COMMUNICATION STOP MODE TABLE

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" (see CHECK CAN BUS LINE ). Select "BUS CHECK" on the hand-held tester via the CAN VIM (see DIAGNOSIS SYSTEM ).
Check the communication stop mode of the ECUs or sensors not displayed among the following: "ENGINE", "ECT", "CRUISE CONTROL", "ABS/VSC/TRAC", "YAW/DECELERAT", "STEERING SENSOR", "BODY/GATEWAY", "BACK GUIDE MONITOR", "PSB" or "AIR SUSPENSION".
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.)
