2001 Chevrolet Monte Carlo V6-3.4L VIN ESECTION Description and Operation
IGNITION COILS AND IGNITION CONTROL (IC) MODULE
Three dual tower ignition coils are mounted to the IC module, and are serviced individually. The IC module performs the following functions:
^ Receives and processes the signals from the 7x CKP sensor
^ Determines the correct coil triggering sequence, this coil sequencing occurs at start-up, and is remembered by the IC module. After the engine is running, the module will continue to trigger the coils in the correct sequence.
^ Determines the correct direction of the crankshaft rotation, and cuts spark and fuel delivery to prevent backfiring if this condition occurs
^ Produces and sends low resolution engine speed signals to the PCM
