Circuit/System Verification

1. Raise and support the drive wheels.

Caution: Support the lower control arms in the normal horizontal position in order to avoid damage to the drive axles. Do not operate the

vehicle in gear with the wheels hanging down at full travel.

2. Support the lower control arms so that the drive axles are in a horizontal position.

3. Start and idle the engine.

4. Place the transmission in second gear and release the clutch pedal.

5. Monitor VSS parameter on the scan tool. The VSS parameter should increase as the drive wheel speed increases.

6. Operate the vehicle within the conditions for running the DTC. You may also operate the vehicle within the conditions that are captured in

the Freeze Frame/Failure Records List.

Circuit/System Testing

1. Disconnect the ECM harness connector X1.
