Circuit/System Verification
- Ignition ON.
- Verify the scan tool Liftgate Secondary Obstacle Detection parameter is between 3-3.5 V.
- If not between 3-3.5 V
Refer to Circuit/System Testing.
- Go to next step: If between 3-3.5 V
- If not between 3-3.5 V
- Verify the scan tool Liftgate Secondary Obstacle Detection parameter is between 3-3.5 V and changes to 2.25-2.75 V as the B71R Liftgate Object Sensor - Right is pressed.
- If not between 2.25-2.75 V or does not change
Test or replace the B71R Liftgate Object Sensor - Right.
- Go to next step: If between 2.25-2.75 V and changes
- If not between 2.25-2.75 V or does not change
- Verify the scan tool Liftgate Secondary Obstacle Detection parameter is between 3-3.5 V and changes to 2.25-2.75 V as the B71L Liftgate Object Sensor - Left is pressed.
- If not between 2.25-2.75 V or does not change
Test or replace the B71L Liftgate Object Sensor - Left.
- Go to next step: If between 2.25-2.75 V and changes
- If not between 2.25-2.75 V or does not change
- All OK.
