Chime Inoperative - Engine Temperature Critical

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 any module connector.
  1. Turn ignition on. Using scan tool, actuate chime. If chime sounds, go to next step. If chime does not sound, replace Central Timer Module (CTM). CTM is located behind right kick panel.
  2. Using scan tool, read PCM DTCs. If no engine coolant temperature related codes exist, go to next step. If engine coolant temperature related codes exist, see appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
  3. Due to difficult access of coolant temperature sensor, Oil Pressure Switch (OPS) will be used to verify CCD bus message from PCM. Disconnect OPS connector. See OPS LOCATION  table. Connect a jumper wire between OPS connector terminals. Start engine and allow to idle for 20 seconds. Increase engine speed to 1600 RPM. If chime sounds, system is currently functioning properly. If chime does not sound, go to next step.

  4. Remove instrument cluster. See appropriate INSTRUMENT PANELS article. Disconnect Instrument cluster 10-pin Gray connector "B". Connect a jumper wire between ground and instrument cluster 10-pin Gray connector terminal No. 7 (Light Green/Orange wire). Turn ignition on. If chime sounds, replace instrument cluster. If chime does not sound, repair open Light Green/Orange wire.
