Door Lock Switch Failure

NOTE: For connector terminal identification and wiring diagrams, see BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST VER-1A  after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Clear trouble codes as needed. See BODY CONTROL COMPUTER - INTRODUCTION article. Using scan tool, read Vehicle Theft Security System (VTSS) inputs/outputs door lock switch status. If scan tool displays RELEASED, system is currently functioning properly. If scan tool does not display RELEASED, go to next step.
  2. Disconnect left door lock switch connector. If scan tool displays RELEASED, replace left door lock switch. If scan tool does not display RELEASED, go to next step.
  3. Disconnect right door lock switch connector. If scan tool displays RELEASED, replace right door lock switch. If scan tool does not display RELEASED, go to next step.
  4. Locate Central Timer Module (CTM). CTM is located behind right kick panel. Disconnect CTM 18-pin connector "B". Using an external voltmeter, measure voltage between ground and CTM 18-pin connector "B" terminal No. 4 (Light Green wire on Dakota or Orange/Violet wire on Durango). If voltage is more than 1.5 volts, repair short to voltage in Light Green wire on Dakota or Orange/Violet wire on Durango between CTM and door lock switch. If voltage is 1.5 volts or less, replace CTM.
