Past trouble

Carry out diagnosis with particular emphasis on connector(s) or wiring harness in the CAN bus lines between the TPMS-ECU and the combination meter, and the power supply system to the TPMS-ECU. For diagnosis procedures, refer to HOW TO TREAT PAST TROUBLE .

NOTE: For a past trouble, you may not find it by the M.U.T.-III CAN bus diagnostics even if there is a failure in CAN bus lines. In this case, refer to HOW TO COPE WITH INTERMITTENT MALFUNCTIONS 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 CONTROLLER AREA NETWORK (CAN) .
