System Diagnosis - Cruise Control

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 Diagnostic Trouble Code (DTC)(s) are stored, check for faulty cruise switch, wiring harness for opens or faulty connections. The cruise control switch on the clutch pedal stuck in the open position will cause a no cruise control complaint.
