Test TC-69B - Injector No. 5 Control Circuit
NOTE:
For connector terminal ID, see CONNECTOR IDENTIFICATION Directory. For wiring diagram, see WIRING DIAGRAMS
article.
- It may be necessary to remove intake plenum for access to injector connectors. Reconnect injector harness 4-pin connector. Disconnect injector No. 5 connector. Turn ignition on. Using scan tool, actuate ASD relay.
- Using scan tool in voltmeter mode, check voltage on injector No. 5 connector ASD relay output circuit Dark Green/Orange wire. If voltage cycles high and low, go to next step. If voltage does not cycle high and low, repair open ASD relay output circuit. Perform TEST VER-2A.
- Turn ignition off. Using an external ohmmeter, check resistance of injector No. 5 driver circuit Gray wire between injector No. 5 connector and PCM connector terminal No. 15. If resistance is less than 5 ohms, replace injector No. 5. Perform TEST VER-2A. If resistance is 5 ohms or more, repair open injector No. 5 driver circuit. Perform TEST VER-2A.
