TEST 15A - Key In Ignition

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagram, see WIRING DIAGRAMS at the end of this article. Perform VERIFICATION PROCEDURE VER-1 after each repair.
CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Ensure ignition switch is in ON position. Using DRB-II, select KEY IN IGNITION SWITCH status. If DRB-II displays KEY IN IGN: CLOSED, go to step 5). If DRB-II does not display KEY IN IGN: CLOSED, go to next step.
  2. Turn ignition switch to OFF position. Disconnect key in light switch connector. Check, clean and repair connections as needed. Connect jumper wire between key in light switch connector terminal No. 3 (Light Blue wire) and terminal No. 4 (Black/Orange wire). Ensure driver's door is open. If DRB-II displays KEY IN IGN: CLOSED, replace key in light switch. If DRB-II does not display KEY IN IGN: CLOSED, go to next step.
  3. Disconnect jumper wire. Connect jumper wire between key in light switch connector terminal No 3 (Light Blue wire) and ground. If DRB-II displays KEY IN IGN: CLOSED, repair Black/Orange wire between key in light switch connector and ground for short to ground. If DRB-II does not display KEY IN IGN: CLOSED, go to next step.
  4. Disconnect jumper wire. Gain access to body control module, located behind right kick panel. With connectors connected, connect jumper wire between body control module Black connector terminal No. 2 (Light Blue wire) and ground. If DRB-II displays KEY IN IGN: CLOSED, repair open in Light Blue wire between body control module Black connector and key in light switch connector.
  5. If DRB-II displays KEY IN IGN: CLOSED in step 1), ensure left door is open. Remove key from ignition switch. If DRB-II displays CIRCUIT OPEN, go to TEST 30A. If DRB-II does not display CIRCUIT OPEN, go to next step.
  6. Disconnect key in light switch connector. Check, clean and repair connections as needed. If DRB-II does not display KEY IN IGN: CLOSED, replace key in light switch. If DRB-II displays KEY IN IGN: CLOSED, go to next step.
  7. Disconnect body control module. Check, clean and repair connections as needed. Put DRB-II in ohmmeter mode. Measure resistance at body control module Black connector terminal No. 2 (Light Blue wire). If resistance is less than 5 ohms, repair Light Blue wire between body control module Black connector and key in light switch connector for short to ground. If resistance is more than 5 ohms, replace body control module.
