Component Tests: Clock

Disconnect clock 8-pin connector. Using a voltmeter, measure voltage between ground and clock 8-pin connector terminal No. 4 (Blue/Yellow wire). See WIRING DIAGRAMS . Battery voltage should exist. Measure voltage between ground and clock 8-pin connector terminal No. 5 (Gray wire). Battery voltage should exist. Measure voltage between ground and clock 8-pin connector terminal No. 1 (White/Black wire). Battery voltage should not exist. If voltages are as specified, replace clock and retest system operation. If voltages are not as specified, repair or replace wire harness and retest system operation.
