If LEFT CYLINDER LOCK SWITCH INPUT SHORT resets, go to next step. If LEFT CYLINDER LOCK SWITCH INPUT SHORT does not reset, system is operating properly at this time. Check for intermittent poor connections or faulty circuits.

- 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. 14 (Violet/Light Blue wire). If resistance is 1000 ohms or less, repair short to ground in Violet/Light Blue wire between cylinder lock switch and BCM. If resistance is greater than 1000 ohms, replace BCM.
