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 cope with past trouble" (Refer to "How to Use Troubleshooting/inspection Service Points - 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 Use Troubleshooting/inspection Service Points - 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
EXPLANATION ABOUT THE SCAN TOOL (M.U.T.-III) CAN BUS DIAGNOSTICS
).
