Diagnostic Test
1. DTC PRESENTWith the scan tool, record DTCs and any liftgate inhibitors.
Erase DTCs.
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 B1965–POWER LIFTGATE SENSOR SUPPLY CIRCUIT LOW?
Yes
- Go To 2
No
- Using the wiring diagram/schematic as a guide, inspect the wiring and connectors for an intermittent condition.
- Perform BODY VERIFICATION TEST - VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE).
2. POWER LIFTGATE DRIVE UNIT
Disconnect the Power Liftgate Drive Unit harness connector.
