Test SA, Display Does Not Respond To Buttons - No Beep Sound When Buttons Pushed Or Driver Alert Given

  1. Verifying Condition Of Each Cluster Control Button: Buttons function in RUN mode only. Warning chime module will not beep if another sound is being produced. If display does not respond to buttons, proceed to step 3). If display responds to buttons but no tone is heard, proceed to step 2).
  2. Checking Warning Chime Module: Check for SAFETY BELT UNFASTENED and KEY IN IGNITION SWITCH warning chimes. If both chimes sound, proceed to step 13). If neither chime sounds, service warning chime module. Warning chime module is located behind instrument panel, near right side of steering column. Warning chime module is lower module, and contains a 10-pin connector. Connector is a flat-type connector with all pin connectors in a straight row.
  3. Checking Switch Wiring Connections: Remove finish panel to expose instrument cluster. Ensure all wiring connections are securely fastened on instrument cluster. Secure wiring connections if loose. If connections are okay, proceed to step 4).
  4. Checking Message Center Switch Module With No Button Depressed: Disconnect wiring connector from message center switch module. Measure resistance between pin No. 1 (Light Blue/Yellow wire) and pin No. 8 (Pink/Orange or Black/Light Blue wire) of message center switch module with no buttons depressed. Resistance with no buttons depressed should be 17,300-17,600 ohms.
  5. If resistance is 17,300-17,600 ohms, proceed to step 6). If resistance is not within specifications, replace message center switch module.
  6. Checking Message Center Switch Module With Buttons Depressed: Disconnect wiring connector from message center switch module. Measure resistance between pin No. 1 (Light Blue/Yellow wire) and pin No. 8 (Pink/Orange or Black/Light Blue wire) of message center switch module with only one button depressed at a time.
  7. Resistance should be within specifications. See the MESSAGE CENTER SWITCH MODULE RESISTANCE SPECS  table. If resistance is within specifications, proceed to step 8). If resistance is not within specifications, replace message center switch module.
    MESSAGE CENTER SWITCH MODULE RESISTANCE SPECS

    Button Depressed Ohms
    E/M 5100-5200
    RESET 1000-1100
    SELECT Right 330-350
    SELECT Left 2250-2350
  8. Checking Instrument Cluster Wiring Connections: Disconnect negative battery cable. Remove instrument cluster. See INSTRUMENT CLUSTER R & I  . Ensure connector C2-2 is properly aligned and secured on instrument cluster. See Figure .
  9. If connection is okay, proceed to step 10). If connection is defective, repair as necessary.
  10. Verifying Wiring Harness Continuity: Disconnect the negative battery cable. Remove the instrument cluster. Refer to INSTRUMENT CLUSTER R & I  . Remove message center switch module. See MESSAGE CENTER SWITCH MODULE  .
  11. Check continuity between pin No. 1 (Light Blue/Yellow wire) of message center switch module and instrument cluster connector C2-2, pin No. 30 (Light Blue/Yellow wire). Check continuity between pin No. 8 (Pink/Orange or Black/Light Blue wire) of message center switch module and instrument cluster connector C2-1, pin No. 4 (Pink/Orange or Black/Light Blue wire).
  12. If continuity exists, replace instrument cluster. Install door pillar sticker to indicate instrument cluster has been replaced. If continuity does not exist, repair wiring circuit.
  13. Checking Tone Circuit: Disconnect negative battery cable. Remove instrument cluster. See INSTRUMENT CLUSTER R & I  . Turn ignition on, and wait for SAFETY BELT UNFASTENED warning chime to end.
  14. Connect jumper wire between instrument cluster connector C2-1, pin No. 11 (Tan/Yellow wire) and ground, and listen for chime. If chime sounds, replace instrument cluster. Install door pillar sticker to indicate instrument cluster has been replaced. If chime does not sound, check for defective warning chime module or defective wiring circuit between instrument cluster and warning chime module.
  15. Warning chime module is located behind instrument panel, near right side of steering column. Warning chime module is lower module, and contains a 10-pin connector. Connector is a flat-type connector with all pin connectors in a straight row.
