2
Ignition on, engine not running.
With the DRBIII
t, erase DTCs.
With the DRBIII
t, perform the Solenoid Test.
With the DRBIII
t, read DTCs.
Did the DTC, TCC SOLENOID CIRCUIT, reset?
All
Yes
→ Go To 3
No
→ Go To 7
3
Turn the ignition off to the lock position.
Disconnect the Transmission Control Module C2 harness connector.
Disconnect the Transmission Solenoid Assembly harness connector
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the TCC Solenoid Control circuit from the TCM C2 harness
connector to the Transmission Solenoid Assembly harness connector.
Is the resistance above 5.0 ohms?
All
Yes
→ Repair the TCC Solenoid Control circuit for an open.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
No
→ Go To 4
4
Turn the ignition off to the lock position.
Disconnect the Transmission Control Module C2 harness connector.
Disconnect the Transmission Solenoid Assembly harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between ground and the TCC Solenoid Control circuit.
Is the resistance below 5.0 ohms?
All
Yes
→ Repair the TCC Solenoid Control circuit for a short to ground.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
No
→ Go To 5
5
Turn the ignition off to the lock position.
Disconnect the Transmission Control Module C2 harness connector.
Disconnect the Transmission Solenoid Assembly harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance of the TCC Solenoid Control circuit to all other circuits in the
Transmission Solenoid Assembly harness connector.
Is the resistance below 5.0 ohms between any other circuit?
All
Yes
→ Repair the TCC Solenoid Control circuit for a short to other
circuits.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
No
→ Go To 6
6
Turn the ignition off to the lock position.
Disconnect the Transmission Control Module C2 harness connector.
Note: Check connectors - Clean/repair as necessary.
Measure the resistance between the TCC Solenoid Control circuit and the Solenoid
Supply Voltage circuit in the Transmission Control Module C2 harness connector.
Is the resistance between 2.0 and 4.0 ohms?
All
Yes
→ Replace the Transmission Control Module.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
No
→ Replace the TCC Solenoid per the Service Information.
Perform NAG1 TRANSMISSION VERIFICATION TEST - VER 1.
