0009-PRNDL CONTROL CIRCUIT LOW





For a complete wiring diagram, Refer to the Wiring Information Electrical Diagrams.

- When Monitored:
Continuously with the ignition key on.

- Set Condition:
This DTC will set if the ESM detects a shorted circuit from the BCM for 10 seconds.





Always perform the NAG1 Pre-Diagnostic Troubleshooting procedure before proceeding. Transmission Pre-Diagnostic Troubleshooting Procedures.

1. DTC STATUS

NOTE: Repair all other DTCs before continuing with this test.

1. Turn the ignition on.
2. Using the scan tool, read DTCs.

Is the DTC active?

Yes

- Go To 2

No

- Go To 5

2. CHECK (U815) TERM.58D CIRCUIT SHORT TO VOLTAGE




1. Turn the ignition off to the lock position.
2. Disconnect the Shift Lever Assembly harness connector.
3. Disconnect the BCM C1 harness connector.
4. Turn the ignition on.
5. Measure the voltage between ground and the (U815) TERM. 58D circuit in the Shift Lever Assembly harness connector.

Is there any voltage present?

Yes

- Go To 3

No

- Repair the (827) Relay Fused Output circuit for an open or high resistance.
- Perform the NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test.

3. CHECK (U815) TERM.58D CIRCUIT SHORT TO GROUND




1. Turn the ignition off to the lock position.
2. Measure the resistance between ground and the (U815) TERM. 58D circuit in the Shift Lever Assembly harness connector.

Is the resistance greater than 5.0 Ohms?

Yes

- Go To 4

No

- Repair the (U815) TERM. 58D circuit for an open or high resistance.
- Perform the NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test.

4. SHIFT LEVER ASSEMBLY (ESM)
1. Reconnect all disconnected harness connectors.
2. With the scan tool, erase ESM DTCs.
3. Start the engine and raise the engine speed to 2000 RPM for at least 10 seconds.
4. With the scan tool, read ESM DTCs.

Did the DTC 0009-PRNDL CONTROL CIRCUIT PERFORMANCE return?

Yes

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

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time. Using the wiring diagrams as a guide, check all related splices and connectors for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

5. INTERMITTENT CONDITION

NOTE: Check for any of the follow conditions:
- Poor wire to terminal connection
- Corroded terminals
- Backed out or loose terminals
- Broken wire internal to the insulation
- Dirty (partial) module ground

Were any of the above condition present?

Yes

- Repair as necessary.
- Perform the NAG1 TRANSMISSION VERIFICATION TEST. NAG1 Transmission Verification Test.

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time.
