B1947

B1947-POWER LIFTGATE PINCH SENSOR 2 CIRCUIT LOW





For a complete wiring diagram refer to Diagrams/Electrical

- When Monitored:

Whenever the Power Liftgate Module is awake.

- Set Condition:

The power liftgate module has detected the right pinch sensor circuit voltage is under 0.5 volts for over 20 seconds.





Diagnostic Test

NOTE: The vehicle should be at room temperature when this test is performed.

1.DTC PRESENT

With the scan tool, record DTC's and any liftgate inhibitors.

Erase DTC's

Turn the ignition off, wait 10 seconds, then turn the ignition on.

Operate the liftgate several times.

With the scan tool, read DTCs.

Does the scan tool display B1947-POWER LIFTGATE PINCH SENSOR 2 CIRCUIT LOW?

Yes

- Go To 3

No

- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for an intermittent condition.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2.RIGHT PINCH SENSOR SHORTED





Turn the ignition off.

Disconnect the Right Pinch Sensor connector

Erase DTC's

Turn the ignition off, wait 10 seconds, then turn the ignition on.

With the scan tool, read DTCs.

Does the scan tool display B1947-POWER LIFTGATE PINCH SENSOR 2 CIRCUIT LOW?

Yes

- Go To 3

No

- Replace the right pinch sensor.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

3.(Q78) RIGHT PINCH SENSOR SIGNAL CIRCUIT SHORT TO THE (Q901) LOGIC GROUND CIRCUIT





Turn the ignition off.

Disconnect the Power Liftgate Module C2 harness connector.

Measure the resistance between the (Q901) Logic Ground circuit and the (Q78) Right Pinch Sensor Signal circuit in the Power Liftgate Module C2 harness connector.

Is the resistance below 10000.0 ohms?

Yes

- Go To 4

No

- Replace the right pinch sensor.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

4.(Q78) RIGHT PINCH SENSOR SIGNAL CIRCUIT SHORT TO GROUND





Measure the resistance between ground and the (Q78) Right Pinch Sensor Signal circuit.

Is the resistance below 10000.0 ohms?

No

- Replace the Power Liftgate Module.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

Yes

- Repair the (Q78) Right Pinch Sensor Signal wire for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
