Passenger Door Lock Switch Input Short

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn ignition on. Using scan tool, clear DTCs. Cycle the ignition from off to on to off. Monitor DTCs on scan tool. Remove the key and operate door locks from passenger's door lock switch. If PASSENGER DOOR LOCK SWITCH INPUT SHORT resets, go to next step. If PASSENGER DOOR LOCK SWITCH INPUT SHORT does not reset, system is operating properly at this time. Check for intermittent poor connections or faulty circuits.
  2. Using scan tool, select SENSORS. Monitor PASS DOOR SW MUX voltage. If voltage is 4.6 volts or less, go to next step. If voltage is greater than 4.6 volts, replace door lock switch.
  3. Locate and disconnect Body Control Module (BCM) connector C3. See COMPONENT LOCATIONS . See Figure. Using DVOM, measure resistance between ground and BCM connector C3 terminal No. 22 (Violet/Light Green wire). If resistance is 1000 ohms or less, repair short to ground in Violet/Light Green wire between door lock switch and BCM. If resistance is greater than 1000 ohms, replace BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.
