Checking Diagnostic Circuit For Short To Ground

  1. Turn ignition off. Open trunk, and lower module package tray behind left side of back seat. Disconnect ARC module 60-pin connector. Ensure Gray/Red wire (circuit No. 844) is securely attached to pin No. 30 at ARC module 60-pin connector.
  2. Using DVOM, check resistance from pin No. 30 to pin No. 60. If resistance is greater than 1000 ohms, proceed to TEST D4. If resistance is less than 10 ohms, repair short to ground in circuit No. 844. Also check for short to ground in White/Purple wire (circuit No. 209).
