What to know about the Cruise Control Brake Release Switch:
When you do begin to decelerate your car, the cruise control will need to be disengaged or deactivated. Your vehicle is furnished with redundant switches to ensure it is feasible to turn off your cruise control even if one switch fails to operate. There is a clutch release switch on vehicles furnished with a manual transmission that cancels the cruise control set speed when the clutch pedal is depressed. There is also an on/off or cancel button on the steering wheel or column that will deactivate the cruise set speed. A vacuum brake bleed control is equipped on older vehicles which will also cut out the cruise control. All vehicles will be furnished with a cruise control brake release switch. When the brake pedal is pressed, a switch on or behind the pedal is hit that opens a circuit. The cruise control servo or module senses a loss of continuity and cancels the cruise control set speed. If the brake release switch is not working and does not ‘open’, the cruise control will not cancel through the brake switch. If the switch will not ‘close’ the circuit, the cruise control will not set in the first place.
Facts to Note:
If the cruise control brake release switch fails, it is still feasible to set the cruise control off by pressing the steering wheel cancel or off button.
A damaged brake light can “backfeed” power, which may cause the same error as a faulty brake release switch. Endeavour to have your brake lights checked first if your cruise control will not work.
How to Fix:
The cruise control brake release switch is confirmed that it needs to be changed. Trim panels above the brake pedals are taken out to reach the switch.
The defective cruise control brake release switch is disconnected from vacuum line and taken out.
The new cruise control brake release switch is fixed, secured and wired back to the vacuum line.
Trim panels are reinstalled. The cruise control brake release switch is checked for operation
The vehicle is road tested to ensure proper operation of the cruise control and the cruise control brake release switch.
It is rampant for a burned out brake light bulb to cause the cruise control to not set, so if the cruise control is inoperative, have the brake lights inspected first. The brake release switch does not need any maintenance and will last the vehicle’s lifetime in many instances; however, it can fail just like any other electrical device. Have the cruise control inspected and repaired by one of your expert technicians if stops functioning.
