Vehicle Speed Sensor "A" No Signal (P050031)
DESCRIPTION
Vehicles, which are equipped with ABS (Anti-lock Brake System), detect the vehicle
speed using the skid control ECU (brake actuator assembly) and speed sensors. Each
speed sensor monitors the wheel rotation speed and sends a signal to the skid control
ECU. The skid control ECU con ...
Control Module Communication Bus OFF (U0073,U0100,U0114,U0123,U0124,U0126)
DESCRIPTION
The skid control ECU (master cylinder solenoid) receives the signals from the
ECM, steering angle sensor (spiral cable with sensor sub-assembly), 4 wheel drive
control ECU*, and yaw rate and acceleration sensor (airbag sensor assembly) via
the CAN communication system.
