- A reference lateral acceleration from the data of the yaw rate sensor, wheel speed sensors, and steering angle sensor is used to test the lateral accelerometer signal. If during stable driving conditions, the lateral accelerometer signal becomes larger than 0.26 g, the electronic brake control module (EBCM) controller will disregard the signal so that a false EBCM intervention is prevented. A malfunction is detected if this condition continues for more than 2 seconds.
- Under normal driving conditions, the long time filtered driving direction is straight ahead. The long time filtered lateral accelerometer value is called the offset. If the offset value is higher than 0.23 g, a malfunction is detected. Malfunction time depends on driving distance, vehicle speed and the amount of malfunctioning later accelerometer signal.
- The lateral accelerometer signal is limited to an electrical stop of 1.8 g. If the lateral accelerometer signal is greater than 1.5 g for more than 500 milliseconds, a malfunction is detected.
- At a standstill, the range of the lateral accelerometer signal is less than 0.7 g. If the lateral accelerometer signal is greater than 0.7 g at standstill, a malfunction is detected.
- Lateral accelerometer signal cannot change rapidly under normal driving conditions. If the lateral accelerometer signal is changing faster than 55 g per second, a malfunction is detected.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
