CHECK FOR INTERMITTENT PROBLEMS

1. CHECK FOR INTERMITTENT PROBLEMS
(a) Perform a simulation test. How To Proceed With Troubleshooting
(1) For the simulation test, reproduce the driving conditions that were present when the trouble occurred. These conditions should be based on the customer's comments and freeze frame data that is recorded with DTCs, such as the opening angle of the accelerator pedal, SOC (state of charge), engine coolant temperature, engine rpm, and MG1/MG2 rpm and torque.
(b) Check the connector(s) and terminal(s). Electronic Circuit Inspection Procedure
(c) Wiggle the harness and connector(s). Electronic Circuit Inspection Procedure
(d) Heat or cool suspected parts. How To Proceed With Troubleshooting
NOTICE:
Do not directly heat or cool the MG ECU with the inverter cover removed.
