Past trouble
- Carry out diagnosis with particular emphasis on connector(s) or wiring harness in the CAN bus lines between the combination meter and the TCL/ASC-ECU, and the power supply system to the combination meter. For diagnosis procedures, refer to "How to cope with past trouble" (Refer to
HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
).
NOTE:
For a past trouble, you may not find it by the M.U.T.-III CAN bus diagnostics even if there is any failure in CAN bus lines. In this case, refer to
HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS
. and check the CAN bus lines. You can narrow down the possible cause of the trouble by referring to the DTC, which is set regarding the CAN communication-linked ECUs (Refer to
CAN BUS LINE DIAGNOSTICS FLOW
).
