Test 57B - Instrument Cluster Sense Circuits

NOTE: Perform TEST 57A  before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION  . For wiring schematics, see WIRING DIAGRAMS  in this article. Perform TEST VER-1 - VERIFICATION PROCEDURE  after each repair.
CAUTION: Always turn ignition off prior to disconnecting any module connector.
  1. Using scan tool, read cluster ID. If scan tool displays CLUSTER ID: CHRY/EAGL, go to step 3). If scan tool does not display CLUSTER ID: CHRY/EAGL, turn ignition off. Disconnect instrument cluster connectors. Using scan tool, read cluster ID. If scan tool displays CLUSTER ID: CHRY/EAGL, replace instrument cluster. If scan tool does not display CLUSTER ID: CHRY/EAGL, go to next step.
  2. Disconnect Body Control Module (BCM) connectors. BCM is located behind right kick panel. Using scan tool in ohmmeter mode, measure resistance at terminal No. 12 (Orange/Dark Blue wire) on BCM Gray connector. If resistance is less than 5 ohms, repair short to ground in Orange/Dark Blue wire. If resistance is 5 ohms or greater, replace BCM.
    NOTE: Metric speedometer head displays KM/H letters larger than MPH letters.
  3. If speedometer is not a metric unit, go to step 6). If speedometer is a metric unit, use scan tool to read instrument cluster mode status. If scan tool displays MIC MODE: KM/H, repair or replace instrument cluster as necessary. See INSTRUMENT PANEL article in the ACCESSORIES & ELECTRICAL section. If scan tool does not display MIC MODE: KM/H, go to next step.
  4. Ensure ignition switch is in OFF position. Disconnect instrument cluster connectors. If scan tool displays MIC MODE: KM/H, repair or replace instrument cluster as necessary. See INSTRUMENT PANEL article in the ACCESSORIES & ELECTRICAL section. If scan tool does not display MIC MODE: KM/H, go to next step.
  5. Disconnect BCM connectors. Using scan tool in ohmmeter mode, measure resistance at terminal No. 7 (Light Blue wire) on BCM Gray connector. If resistance is less than 5 ohms, repair short to ground in Light Blue wire. If resistance is 5 ohms or greater, replace BCM.
  6. Using scan tool, read MIC mode status. If scan tool displays MIC MODE: MPH, repair or replace instrument cluster as necessary. See INSTRUMENT PANEL article in the ACCESSORIES & ELECTRICAL section. If scan tool does not display MIC MODE: MPH, go to next step.
  7. Ensure ignition switch is in OFF position. Disconnect instrument cluster connectors and BCM connectors. Turn ignition on. Using scan tool in voltmeter mode, measure voltage at terminal No. 7 (Light Blue wire) on BCM Gray connector. If voltage is more than 10 volts, repair short to battery voltage in Light Blue wire and replace instrument cluster. See INSTRUMENT PANEL article in the ACCESSORIES & ELECTRICAL section. If voltage is 10 volts or less, go to next step.
  8. Reconnect BCM connectors. Connect jumper wire between ground terminal No. 9 (Light Blue wire) and instrument cluster Black connector. If scan tool displays MIC MODE: MPH, repair or replace instrument cluster. See INSTRUMENT PANEL article in the ACCESSORIES & ELECTRICAL section. If scan tool does not display MIC MODE: MPH, go to next step.
  9. Disconnect jumper wire. Gain access to BCM. Connect jumper wire between ground and terminal No. 7 (Light Blue wire) on BCM Gray connector. If scan tool displays MIC MODE: MPH, repair open Light Blue wire. If scan tool does not display MIC MODE: MPH, replace BCM.
