Code Description
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. FDCS controls fuel injection timing and controls fuel quantity with Injection Pressure Regulator (IPR). This signal is sent with the Cylinder Identification (CID) signal to the Injector Driver Module (IDM) which provides power and distributes the proper signal to appropriate injector. This test is intended to diagnose:
- Injector Driver Module
- Wiring Harness Circuit (FDCS)
- Powertrain Control Module (PCM)
