Chime Test 6A - Chime Inoperative With Extreme Coolant Temperature
NOTE:
Perform CHIME TEST 1A
before proceeding with this test. For connector terminal identification, refer to CONNECTOR IDENTIFICATION
. For wiring diagrams, refer to WIRING DIAGRAMS
. Perform, after each repair, VERIFICATION TEST VER-1A - VERIFICATION PROCEDURE
.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting any module connector.
- 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.
- Using scan tool, read DTCs. If no engine coolant temperature related codes exist, go to next step. If engine coolant temperature related codes exist, see TESTS W/CODES article in the ENGINE PERFORMANCE Section.
- 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 in TEST 5A. Go to next step.
- 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.
- Remove instrument cluster. See INSTRUMENT PANEL - ANALOG article for Dakota or see INSTRUMENT PANEL - ANALOG article for Durango. Disconnect Instrument cluster 10-pin Gray connector "B". Connect a jumper wire between ground and Light Green/Orange wire of instrument cluster 10-pin Gray connector terminal No. 7.
- Turn ignition on. If chime sounds, replace instrument cluster. If chime does not sound, repair open Light Green/Orange wire.
