Code Description
WARNING:
Injector Driver Module (IDM) supplies 115-volts DC into each fuel injector connected to engine wiring harness. Severe electrical shock hazard exists. DO NOT pierce wires.
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.
NOTE:
Each valve cover gasket has 2 fuel injector connectors that are part of the gasket. Each connector is responsible for 2 fuel injectors. If connector is faulty, replace valve cover gasket.
Perform this test when directed by QUICK TEST. Injector Driver Module (IDM) is capable of detecting individual injector open and shorts to either ground or power while engine is running. IDM is also capable of detecting right or left bank high side circuit opens or shorts to ground.
