Test 10B - Repairing Sense Circuits On Electro/Mechanical Instrument Cluster
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION. For wiring diagrams, see WIRING DIAGRAMS
article in the ENGINE PERFORMANCE Section. Perform TEST VER - 1A after each repair.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Stop faulty gauge actuation test. Turn ignition switch to OFF position. Disconnect Mechanical Instrument Cluster (MIC) connector. Check connector, and clean or repair connector as necessary.
- Using an external ohmmeter, check resistance of low MIC sense circuit between MIC connector terminal No. 3 (Orange/Dark Blue wire) and Natural body controller connector terminal No. 10 (Orange/Dark Blue wire).
- If resistance is more than 5 ohms, repair open Orange/Dark Blue wire. If resistance is less than 5 ohms, check resistance of high MIC sense circuit between MIC connector terminal No. 5 (Light Blue wire) and Natural body controller connector terminal No. 12 (Light Blue wire).
- If resistance is more than 5 ohms, repair open Light Blue wire. If resistance is less than 5 ohms, replace body controller.
