- Using DRB, erase trouble codes. Attempt to start engine. If engine will not start, crank engine for at least 10 seconds.
- Using DRB, read trouble codes. If engine started, allow engine to idle for at least 20 seconds. If DRB does not display INJECTOR CONTROL CIRCUIT, go to next step. If DRB displays INJECTOR CONTROL CIRCUIT, go to step 6).
- At this time, condition required to set trouble code is not present. INJECTOR CONTROL CIRCUIT trouble code sets if Powertrain Control Module (PCM) does not detect an inductive kick .18 ms after injector turn off with no other injectors on. Possible causes are: open or shorted injector control circuit, open injector power supply circuit, open injector, or failed driver in Powertrain Control Module (PCM). Go to next step.
- Inspect all related wiring and connectors and repair as necessary. Perform TEST VER-2 . If no problems are found with wiring and connectors, go to next step.
- Start engine. Wiggle injector-to-PCM wiring harness. If engine misfires or stalls, repair wiring harness as necessary. Perform TEST VER-2. If engine does not misfire or stall, see INACTIVE TROUBLE CODE CONDITION . Perform TEST VER-2.
- See INJECTOR TROUBLE CODE table.
