NOTE:
After each service or repair procedure has been completed, reconnect all components. Clear DTCs and repeat QUICK TEST procedures to ensure all electronic engine control systems are working properly and DTCs are no longer present.
Perform this test when directed by QUICK TEST. This test is only intended to diagnose the following components and circuits:
- Injector Driver Module (IDM)
- Wiring Harness Circuits (CID & SIG RTN)
- Powertrain Control Module (PCM)
The CID output from PCM provides information to IDM so that injector current can be supplied to correct injector.
