If IOD WAKE UP OPEN - PLG resets, go to next step. If IOD WAKE UP OPEN - PLG does not reset, system is operating properly at this time. Check for intermittent poor connections or faulty circuits.
  2. Turn ignition off. Locate and disconnect Body Control Module (BCM) connector C2. See COMPONENT LOCATIONS . See Figure. Using DVOM, measure voltage between ground and BCM connector C2 terminal No. 17 (Violet/Yellow wire). If voltage is 10 volts or less, go to next step. If voltage is greater than 10 volts, replace BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.
  3. Disconnect Power Liftgate Module (PLGM) connector C1. See Figure. To access connector, left rear trim will need to be removed. See POWER LIFTGATE MODULE  under REMOVAL & INSTALLATION. Using DVOM, measure resistance of Violet/Yellow wire between BCM connector C2 terminal No. 17 and PLGM connector C2 terminals No. 19. If resistance is 5 ohms or less, go to next step. If resistance is greater than 5 ohms, repair open in Violet/Yellow wire.
