Cruise Control Signal Diagnosis:






CIRCUIT DESCRIPTION
The cruise on/off, set/coast and resume/accel signals are inputs to the fuel control portion of the Powertrain Control Module (PCM). These inputs allow the PCM to control and hold a requested speed.
If cruise is inoperative, and no DTCs are stored, check for faulty cruise switch, wiring harness for opens or faulty connections.
