Test 10A - Identifying Faulty Gauge 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.

If all gauges are inoperative, go to TEST 12D. If one or more gauge is okay, actuate faulty gauge in Electro/Mechanical Instrument Cluster (MIC) using DRB-II. This should actuate gauge from LO to HI, and then return it to its original position. If more than one gauge actuated, go to TEST 10B. If tested gauge did not actuate, go to TEST 10C.

If tested gauge did actuate, stop faulty gauge actuation test. Identify faulty gauge and go to appropriate test. See FAULTY GAUGE TEST table.

⁽¹⁾	If tachometer is not functioning correctly, go to step 3).

Start engine and using DRB-II, read engine RPM. If RPM is less than 400 RPM, see appropriate G - TESTS W/ CODES article in the ENGINE PERFORMANCE Section. If RPM is more than 400 RPM, and tachometer head has not been replaced previously, replace tachometer head. If tachometer head is not damaged and has been replaced before, replace MIC printed circuit.
