Turn the ignition off to the lock position.
Disconnect the Input Speed Sensor harness connector.
Disconnect the TCM harness connector.
Remove the Transmission Control Relay from the PDC.
Note: Check connectors - Clean/repair as necessary.
Connect a jumper wire between the Fused B+ circuit and the Transmission Control
Relay Output circuit in the Transmission Control Relay connector.
Ignition on, engine not running.
Measure the voltage of the Input Speed Sensor Signal circuit in the TCM harness
connector.
