Cruise Control Deactivation Switch Circuit Malfunction
There’s a problem with the cruise control system's deactivation switch.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The cruise control system can’t turn off properly because the switch that tells it when to turn off isn’t working right.
What the computer is actually seeing
The vehicle's control module detects abnormal voltage levels or signals from the cruise control deactivation switch, which should normally show a closed or open circuit based on the switch position.
What a healthy reading looks like
Voltage should be near 0V when the switch is pressed (deactivating) and near battery voltage (12V to 14V) when released.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the cruise control deactivation switch for physical damage.
- 2Inspect the wiring and connectors for fraying or corrosion, ensure they are securely connected.
- 3Use a multimeter to measure voltage at the switch: should toggle between 0V and 12V when engaged and disengaged, respectively.
- 4If the readings are correct, test the continuity of the wiring from the switch to the control module. Replace any damaged wiring.
Common causes
- Faulty deactivation switch
- Wiring issue or short circuit
- Corroded connector pins
- Faulty cruise control module
