- Using scan tool, erase DTCs. Attempt to start engine; crank engine for at least 10 seconds if necessary.
- Allow engine to idle for at least 20 seconds. Using scan tool, read DTCs. If scan tool displays INJECTOR CONTROL CIRCUIT, go to step TEST TC-13B. If scan tool does not display INJECTOR CONTROL CIRCUIT, condition required to set DTC is not present at this time. Go to next step.
- INJECTOR CONTROL CIRCUIT DTC takes .64-10 seconds to set if Powertrain Control Module (PCM) does not detect an inductive kick .18 ms after injector turns off with no other injectors on. Possible causes are: open or shorted injector ground circuit, open injector power supply circuit, open injector, or failed driver in 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 wiring harness from injector to PCM. If engine misfires or stalls, repair wiring harness as necessary. Perform TEST VER-2. If engine does not misfire or stall, see INACTIVE DTC CONDITION . Perform TEST VER-2.
