Passenger Door Lock Switch Input Stuck

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn ignition on. Using scan tool, clear DTCs. Cycle ignition on to off to on. Monitor DTCs on scan tool. Remove the key and operate door locks from passenger's door lock switch. If PASSENGER DOOR LOCK SWITCH INPUT STUCK resets, go to next step. If PASSENGER DOOR LOCK SWITCH INPUT STUCK 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 LOCK SW voltage. If voltage is 1.3-3.25 volt, go to next step. If voltage is not 1.3-3.25 volts, replace BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.
  3. Disconnect passenger's door lock switch connector. See Figure. To access connector, door lock switch will need to be removed. See DOOR LOCK SWITCH under REMOVAL & INSTALLATION in POWER DOOR LOCKS & LIFTGATE RELEASE article. Using a test light connected to battery voltage, probe power door lock switch connector terminal No. 3 (Black/Light Green wire). If test light illuminates, go to next step. If test light does not illuminate, repair open in Black/Light Green wire between door lock switch and ground located on right "B" pillar.
  4. Using DVOM, measure voltage between ground and door lock switch connector terminal No. 2 (Violet/Light Green wire). If voltage is 4.6 volts or less, repair open in Violet/Light Green wire between door lock switch and BCM connector C3 terminal No. 22. See Figure. If voltage is greater than 4.6 volts, replace door lock switch.
