Past Trouble

Carry out diagnosis with particular emphasis on connector(s) or wiring harness in the CAN bus lines between the powertrain control module and the combination meter, and the power supply system to the powertrain control module. For diagnosis procedures, refer to "How to cope with past trouble" under HOW TO COPE WITH INTERMITTENT MALFUNCTION .
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 COPE WITH INTERMITTENT MALFUNCTION .) 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 EXPLANATION ABOUT THE SCAN TOOL (M.U.T.-III) CAN BUS DIAGNOSTICS ).
