Turn the ignition off to the lock position.
Disconnect the TCM harness connector.
Disconnect the Output Speed Sensor harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between ground and the Output Speed Sensor Signal circuit.
Is the resistance Below 5.0 ohms?
All
Yes
→ Repair the Output Speed Sensor Signal circuit for a short to
ground.

Turn ignition off to the lock position.
Disconnect the TCM harness connector.
Disconnect the Transmission Simulator.
Remove the Transmission Control Relay from the PDC.
Note: Check connectors - Clean/repair as necessary.
Connect a jumper wire between the Fused B(+) and Transmission Control Relay
Output circuits in the Transmission Control Relay connector (In PDC).
Ignition on, engine not running.
Measure the voltage of the Output Speed Sensor Signal circuit in the TCM connector.
Is the voltage above 3.0 volts?
All
Yes
→ Repair Output Speed Sensor Signal circuit short to voltage.
