Past Trouble

If DTC 011 or 012 is stored as a past trouble, carry out diagnosis with particular emphasis on wiring and connector(s) in the CAN bus line between the ETACS-ECU and the powertrain control module, and the power supply system to the powertrain control module. For diagnosis procedures, (Refer to HOW TO USE TROUBLESHOOTING/INSPECTION SERVICE POINTS ).
NOTE: You cannot find a past trouble, by the MUT-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 and 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 (MUT-III) CAN BUS DIAGNOSTICS ).
