Diagnostic Test


1. PRE-DIAGNOSTIC CHECKOUT





NOTE: Low fluid level can be the cause of many transmission problems. If the fluid level is low, locate and repair the leak, then check and adjust the fluid level.

NOTE: Always perform diagnostics with a fully charged battery to avoid false symptoms.

With the DRB III(R), read Engine DTCs. Check and repair all engine DTCs prior to performing transmission symptom diagnostics.

With the DRB III(R), read and record all Transmission DTCs.


NOTE: Check connectors - Clean/Repair as necessary. Poor pin to terminal connections can set DTCs.

Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.

Repair as necessary.

Most DTCs set on start-up but some must be set by driving the vehicle such that all diagnostic monitors have run.


NOTE: Check for any Technical Service Bulletins that may apply.

Perform this procedure prior to Symptom diagnosis.

- Refer to the Shift Lever Assembly category and perform the appropriate symptom.

No

- Go To 4



4. CAN C BUS (+) OR (-) CIRCUIT(S) OPEN





Turn the ignition off.

Disconnect the Shift Lever Assembly harness connector.


NOTE: Check connectors - Clean/repair as necessary.

Measure the resistance between the CAN C BUS (+) circuit and the CAN C BUS (-) circuit in the Shift Lever Assembly harness connector.

Is the resistance 60 ohms ±3.0 ohms?

Yes

- Replace the Shift Lever Assembly.
- Perform NAG1 TRANSMISSION VERIFICATION TEST. Transmission Verification Test

No

- Repair the faulty CAN C BUS circuit for an open.
- Perform NAG1 TRANSMISSION VERIFICATION TEST. Transmission Verification Test
