TEST
7 Turn ignition off to the lock position.
Disconnect the TCM harness connector.
Disconnect the Transmission Solenoid/Pressure Switch connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the L/R Pressure Switch Sense circuit from the TCM
connector to the transmission solenoid/pressure switch connector.
Is the resistance above 5.0 ohms?
Yes → Repair the open L/R Pressure Switch Sense circuit.
→ Go To 8
No
8 Turn ignition off to the lock position.
Disconnect the TCM harness connector.
Remove the Transmission Control Relay from the PDC.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the Transmission Control Relay Output circuits between
the relay and the TCM connector. Measure at all three TCM terminals.
Is the resistance above 5.0 ohms on any circuit?
Yes → Repair the open Transmission Control Relay Output circuit
→ Go To 9
No
9 Turn ignition off to the lock position.
Disconnect the TCM harness connector.
Disconnect the Transmission Solenoid/Pressure Switch connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between the L/R Pressure Switch Sense circuit and ground.
Is the resistance below 5.0 ohms?
Yes → Repair L/R Pressure Switch circuit short to ground.
→ Go To 10
No
10 Turn ignition off to the lock position.
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(+) and Transmission Control Relay
Output circuits in the Transmission Control Relay connector (In PDC).
Ignition on, engine not running.
Measure the voltage of the L/R Pressure Switch Sense circuit in the TCM connector.
Is the voltage above 3.0 volts?
Yes → Repair L/R Pressure Switch Sense circuit short to voltage.
→ Go To 11
No
