Loopback Test Failure

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.

Using scan tool, record and erase DTCs. Turn ignition off. Wait 10 seconds. Turn ignition on. Operate power liftgate several times from full open to full closed position if possible. Recheck for DTCs. If LOOPBACK TEST FAILURE resets, replace Power Liftgate Module (PLGM). See POWER LIFTGATE MODULE  under REMOVAL & INSTALLATION. If LOOPBACK TEST FAILURE does not reset, system is operating properly at this time. Check for intermittent poor connections or faulty circuits.
