For a complete wiring diagram Refer to the Wiring Information

- When Monitored:
During Power Liftgate closing cycle.

- Set Condition:
If the Power Liftgate Module detects that the Power Liftgate Drive Unit has generated excessive pulses during a full power cycle, this code will set.





1. DTC PRESENT
1. With the scan tool, record and erase DTCs.
2. Turn the ignition off, wait 10 seconds, then turn the ignition on.
3. Operate the Power Liftgate several times from stop to stop if possible.
4. With the scan tool, read ACTIVE DTCs.

Does the scan tool display B196C-POWER LIFTGATE CLOSE DIRECTION EXCESSIVE POSITION SENSOR COUNTS?

Yes

- Go To 2

No

- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for an intermittent condition. Operate the liftgate several times and check for any binding conditions.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. BINDING LIFTGATE
1. Examine the liftgate for proper alignment, worn or binding hinges, weak liftgate prop assembly, loose/hard weatherstrip, for wear or anything that would cause an obstruction to proper operation.
2. If necessary manually operate the power liftgate on a known good vehicle and notice the effort needed to open and close for comparison.

Were there any mechanical problems found?

Yes

- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. POWER LIFTGATE MODULE - POSITION SENSE OPEN
1. Operate the liftgate from the full closed position and put an obstacle in it's path to make it reverse.

Did the liftgate reverse back to the closed position?

Yes

- Go To 4

No

- Replace the Power Liftgate Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

4. (Q901) LOGIC GROUND OPEN




1. Measure the resistance between the (Z800) Ground and the (Q901) Logic Ground circuit in the Power Liftgate Drive Unit harness connector.

Is the resistance below 9.5 ohms?

Yes

- Go To 5

No

- NOTE: The (Q901) Logic Ground circuit is grounded through the Power Liftgate Module and the (Z800) Ground circuit.
- Repair the (Q901) Logic Ground circuit for an open.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

5. POWER LIFTGATE DRIVE UNIT
1. Reconnect all harness connectors.
2. Operate the Power Liftgate in both directions if possible.

Does the motor start to lift the liftgate but moves very slow and labors extensively?

Yes

- Replace the Power Liftgate Drive Unit assembly.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Power Liftgate Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
