  1. One-Touch Down Feature Operation Test: Ensure standard power windows operate properly. Turn ignition on. Press driver's power window down switch for less than 1/2 second. If driver's window does not move all the way down, go to next step. If driver's window moves all the way down, go to step 5).
  2. Power Window Input To Driver's Door Module (DDM): Connect NGS tester to Data Link Connector (DLC). Turn ignition on. Access DDM. Request IGN_DDM PID. If PID indicates ACCESSORY, go to next step. If PID does not indicate ACCESSORY, repair Yellow/Light Green wire between instrument panel fuse panel and DDM. Retest system.
  3. DDM Logic Ground Test: Turn ignition off. Disconnect negative battery cable. Unplug 18-pin connector from DDM located in left front door. Check for continuity of Black wire between connector and ground. If continuity exists, reconnect 18-pin connector and battery. Go to next step. If there is no continuity, repair open in Black wire. Retest system.
