1. Wheel Speed Sensors: The wheel speed sensors are responsible for sending signals to the ABS module about the speed of each wheel. If one or more of these sensors is faulty, it can cause the ABS light to come on and the speedometer and odometer to give incorrect readings. Check the wheel speed sensors for damage or debris and make sure they are properly connected.
2. ABS Module: The ABS module is responsible for controlling the ABS system. If the ABS module is faulty, it can cause the ABS light to come on and the speedometer and odometer to give incorrect readings. Check the ABS module for any signs of damage or corrosion and make sure it is properly connected.
3. Faulty Wiring: Faulty wiring can also cause the ABS light to come on and the speedometer and odometer to give incorrect readings. Check the wiring to the ABS module and wheel speed sensors for any damage or corrosion and make sure all the connections are secure.
4. Transmission Speed Sensor: The transmission speed sensor is responsible for sending signals to the speedometer and odometer about the speed of the transmission. If the transmission speed sensor is faulty, it can cause the speedometer and odometer to give incorrect readings. Check the transmission speed sensor for any signs of damage or corrosion and make sure it is properly connected.
If you are not comfortable performing these checks yourself, it is best to take your vehicle to a qualified mechanic who can diagnose the problem and make the necessary repairs.
