(1) For the simulation test, reproduce the driving conditions that were present when the problem 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 speed, and generator (MG1)/front motor (MG2)/rear motor (MGR) rpm and torque.

(b) Check the connector(s) and terminal(s).
