CHECK FOR INTERMITTENT PROBLEMS

a. Perform a simulation test
1. In the simulation test, reproduce the driving condition at the trouble occurrence according to the customer's comments and freeze frame data recorded with DTCs, such as an opening angle of the accelerator pedal, SOC, engine coolant temperature, engine rpm, and Motor/Generator/Rear Motor rpm and torque.

b. Check the connector(s) and terminal(s)
c. Wiggle the harness and connector(s)
d. Heat or cool suspected parts

NOTE: Do not directly heat or cool the MG ECU with the inverter cover removed.
