Cruise Control – HFV6 Page 8C–14 2.4 Cruise Control Inoperative / Circuit Description When the ON-OFF button is pressed, 12 V is applied to the Powertrain Interface Module (PIM) connector B – 97 pin 14. Pressing the cruise control switch assembly to SET–COAST button activates the cruise control at a desired speed above Pressing and holding the cruise control switch to SET–COAST provides a 12 V signal to the PIM at connector B – 97 Pressing the brake pedal opens the cruise Initial Brake Apply Signal circuit thus removing the supply voltage from the Manual Vehicles Only Pressing the clutch pedal opens the cruise cancel circuit thus removing the supply voltage from the ECM at connector C For detailed information refer to 3.4 Clutch Pedal Switch (Manual Only) in this Section. Test Description The following numbers refer to the step numbers in the diagnostic table: 4–7 Checks the cruise control switch and associated circuits are functioning correctly. 8–9 Checks the brake pedal switch assembly and associated circuit are functioning correctly. 10 Checks the clutch pedal switch assembly and associated circuits are functioning correctly. 11–21 Covers the testing and replacement of system components. 22–28 Checks for intermittent faults in associated circuits and connectors. Diagnostic Table Notes 1 For all wiring harness fault diagnoses and repairs, refer to 2.3 Wiring Diagrams in this Section. 2 Tech 2 can display a stored history of which system parameter or input caused the cruise control to disengage.
