Test TC-61A: Injector No. 4 Control Circuit
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.
- Turn ignition off. Disconnect injector No. 4 connector. Using an ohmmeter, check resistance across injector No. 4 terminals. If resistance is 10-16 ohms, go to next step. If resistance is not 10-16 ohms, replace injector No. 4. Perform TEST VER-2A .
- Turn ignition on. Using scan tool, actuate ASD relay. Using a voltmeter, check voltage on injector No. 4 connector ASD relay output circuit. See INJECTOR NO. 4 CONNECTOR WIRE IDENTIFICATION table. 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. Disconnect Powertrain Control Module (PCM) connector. Using an ohmmeter, check resistance of injector No. 4 driver circuit at PCM connector terminal No. 16. See PCM CONNECTOR WIRE IDENTIFICATION table. If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground on injector No. 4 driver circuit. Perform TEST VER-2A .
- Using an ohmmeter, check resistance of injector No. 4 driver circuit between injector No. 4 connector and PCM connector terminal No. 16. See INJECTOR NO. 4 CONNECTOR WIRE IDENTIFICATION table and PCM CONNECTOR WIRE IDENTIFICATION table. If resistance is less than 5 ohms, replace PCM. Perform TEST VER-2A . If resistance is 5 ohms or more, repair open injector No. 4 driver circuit. Perform TEST VER-2A .
