- Set Condition:
When the Power Liftgate Module senses the direction of the drive motor is in opposition to the direction it is trying to drive the liftgate, this code will set.





1. DTC PRESENT
1. With the scan tool, record the DTCs.
2. Erase the DTCs.
3. Turn the ignition off, wait 10 seconds, then turn the ignition on.
4. If possible, operate the liftgate several times.
5. With the scan tool, read the Active DTCs.

Does the scan tool display; B1952-00-POWER LIFTGATE DRIVE MOTOR - INCORRECT DIRECTION?

Yes

- Go To 2

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 poor pin fit.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. (Q88) LIFTGATE OPEN DRIVER CIRCUIT AND THE (Q89) LIFTGATE CLOSE DRIVER CIRCUITS ARE CROSSED




1. Turn the ignition off.
2. Disconnect the Power Liftgate Module C1 harness connector.
3. Disconnect the Power Liftgate Drive Unit harness connector.
4. Inspect the Power Liftgate Drive Unit and Power Liftgate Module connectors, terminals and harness for damaged or pushed out terminals, or pinched/broken wires. Repair any obvious problems.
