Left Cylinder Lock Switch Input Stuck

NOTE: When this DTC is set, Vehicle Theft Security System (VTSS) indicator will stay on during VTSS arming process.
NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. Turn ignition on. Using scan tool, clear DTCs. Cycle the ignition switch from on to off to on. Monitor DTCs on scan tool. Remove the key. Operate driver's door cylinder lock switch. If LEFT CYLINDER LOCK SWITCH INPUT STUCK resets, go to next step. If LEFT CYLINDER 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 LEFT CYL LOCK SW voltage. If voltage is 1.30-3.25 volts, go to next step. If voltage is not 1.30-3.25 volts, replace BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.
  3. Disconnect left cylinder lock switch connector. See Figure. To access connector, door panel will need to be removed. For removal and installation procedures, see POWER SLIDING DOOR MODULE  under REMOVAL & INSTALLATION. Using a test light connected to battery voltage, probe cylinder lock switch connector terminal No. 1 (Black/Light Blue wire). If test light illuminates, go to next step. If test light does not illuminate, repair open in Black/Light Blue wire between cylinder lock switch and ground.
  4. Using DVOM, measure voltage between ground and cylinder lock switch connector terminal No. 2 (Violet/Light Blue wire). If voltage is 4.6 volts or less, repair open in Violet/Light Blue wire between cylinder lock switch and BCM connector C3 terminal No. 14. See Figure. If voltage is greater than 4.6 volts, replace cylinder lock switch.
