Speedometer Malfunction |
DESCRIPTION
The combination meter assembly receives vehicle speed signals from the skid control ECU (brake actuator assembly) via CAN communication. The speed sensor detects the wheel speed and sends the appropriate signals to the skid control ECU (brake actuator assembly). The skid control ECU (brake actuator assembly) supplies power to the vehicle speed sensor. The skid control ECU (brake actuator assembly) detects vehicle speed signals based on pulses of the voltage.
HINT:
Factors that affect the indicated vehicle speed include the tire size, tire inflation, and tire wear. The speed indicated on the speedometer has an allowable margin of error.
