Circuit/System Verification

1. Operate the vehicle in second gear long enough to ensure at least a 3掳C (5掳F) rise in TCM temperature.

2. Operate the vehicle in drive range. Allow the transmission to shift through all forward gear ranges. Verify with a scan tool the following test

status parameters display OK:

* Pressure Control Solenoid Valve 5 Performance Test Status

* Pressure Control Solenoid Valve 5 Control Circuit High Voltage Test Status

* Pressure Control Solenoid Valve 5 Control Circuit Low Voltage Test Status

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.
