Interior Light Function Inoperative

  1. Check Interior Light Circuit

    Turn ignition off. Place interior light switch in DOOR position. Using DVOM, measure voltage (backprobe) between ground and terminal No. 21 (White wire) at 12-pin Smart Entrance Control Unit (SECU) harness connector. Measure voltage (backprobe) between ground and terminal No. 22 (Brown/White wire) at 12-pin SECU harness connector. See WIRING DIAGRAMS  . If battery voltage is present at both terminals, leave DVOM connected and go to next step. If battery voltage is not present at both terminals, repair wiring harness between interior light and SECU.
  2. While observing DVOM, press unlock button on remote transmitter. DVOM should indicate zero volts at both terminals. DVOM should indicate battery voltage at both terminals with unlock button released. If voltage is as specified, recheck system. If voltage is not as specified, replace SECU.
