Past trouble

WARNING: This page is about a different car, the 2014 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.

Carry out diagnosis with particular emphasis on connector(s) or wiring harness in the CAN bus lines between the ETACS-ECU and the heater controller assembly (A/C-ECU), and the power supply system to the ETACS-ECU. For diagnostic procedures, refer to "HOW TO TREAT PAST TROUBLE " (Refer to HOW TO TREAT PAST TROUBLE ).

NOTE: For a past trouble, you can 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 diagnostic trouble code, which is stored regarding the CAN communication-linked ECUs (Refer to CAN BUS LINE DIAGNOSTIC FLOW ).
