Is your car acting strange? A bad Chassis Control Module (CCM) can cause a lot of problems. Here's how to tell if yours might be failing:
- Warning lights: You might see ABS, traction control, or stability control lights on your dashboard.
- Erratic handling: The car might feel unstable, especially when turning or braking.
- Stiff steering: Steering might become harder than usual.
- Braking issues: Your brakes might feel grabby, weak, or the ABS might activate unnecessarily.
- Error codes: A mechanic can read trouble codes related to the chassis control system.
How to test it:
- Get the trouble codes read by a mechanic. This will point you in the right direction.
- Check the wiring and connections to the CCM. Look for loose wires or corrosion.
- A mechanic can use a scan tool to monitor the CCM's data and see if it's sending the correct signals.
- Sometimes, a faulty wheel speed sensor can mimic CCM problems. Rule those out first.
Common causes of failure:
- Water damage: If the CCM gets wet, it can short out.
- Electrical surges: Power spikes can damage the module.
- Vibration: Constant vibration can weaken the internal components.
- Age: Like any electronic part, the CCM can simply wear out over time.
