BODY CONTROL COMPUTER - INTRODUCTION article. Perform VERIFICATION TEST VER-1A
after each repair.
- Disconnect amplifier 10-pin connector C2. Amplifier is located under right side of instrument panel in cowl area. Turn radio on. Using an external voltmeter, measure voltage between ground and amplifier 10-pin connector C2 terminal No. 9 (Dark Blue/White wire). If voltage is 4.5-5.5 volts, go to next step. If voltage is not 4.5-5.5 volts, repair ground in Dark Blue/White wire.
- Measure voltage between ground and amplifier 10-pin connector C2 terminal No. 3 (Dark Blue/Orange wire). If voltage is 4.5-5.5 volts, go to next step. If voltage is not 4.5-5.5 volts, repair ground in Dark Blue/Orange wire.
- Measure voltage between ground and amplifier 10-pin connector C2 terminal No. 6 (Violet wire). If voltage is 4.5-5.5 volts, go to next step. If voltage is not 4.5-5.5 volts, repair ground in Violet wire.
- Measure voltage between ground and amplifier 10-pin connector C2 terminal No. 2 (Dark Blue/Red wire). If voltage is 4.5-5.5 volts, replace radio. If voltage is not 4.5-5.5 volts, repair ground in Dark Blue/Red wire.
