ABS / Brakes Codes

Left Front Wheel Speed Sensor Circuit

Fault in the left front wheel speed sensor circuit. This affects ABS and traction control.

Right Front Wheel Speed Sensor Circuit

Fault in the right front wheel speed sensor circuit. ABS, traction control, and stability control depend on wheel speed sensor data.

Right Front Wheel Speed Sensor Range/Performance

The right front wheel speed sensor signal is erratic or outside expected range.

Left Rear Wheel Speed Sensor Circuit

The ABS/EBCM has detected an abnormal or missing signal from the left rear wheel speed sensor (WSS), which is used to calculate wheel speed for ABS and traction/stability control.

Right Front Wheel Speed Sensor Circuit

Fault in right front wheel speed sensor circuit.

ABS Solenoid 1 A Circuit

The ABS/EBCM has detected an electrical fault in the ABS hydraulic modulator's solenoid 1A circuit, which controls hydraulic pressure to one of the wheel brake circuits during ABS activation.

Left Rear Wheel Speed Sensor Circuit

Left rear wheel speed sensor circuit fault.

Right Rear Wheel Speed Sensor Circuit

Right rear wheel speed sensor circuit fault.

Stoplamp Switch Circuit Malfunction

The brake/stoplamp switch circuit used by the ABS and cruise control systems has an electrical fault.

Steering Wheel Angle Sensor Circuit

The vehicle's stability control module has detected a fault in the steering wheel angle sensor circuit, which reports how far and how fast the steering wheel is turned to the ESC and ABS systems.

Left Front Wheel Speed Sensor Circuit Range/Performance

The left front wheel speed sensor signal is outside the expected range compared to other wheels.

Left Rear Wheel Speed Sensor Circuit Range/Performance

The left rear wheel speed sensor signal is outside the expected range compared to other wheels.

Right Rear Wheel Speed Sensor Circuit Range/Performance

The right rear wheel speed sensor signal is outside the expected range compared to other wheels.

Yaw Rate Sensor Circuit Malfunction

The yaw rate sensor, which measures the vehicle's rotation around its vertical axis for stability control, has a circuit fault.

Left Front ABS Solenoid #1 Circuit Malfunction

The ABS hydraulic control unit solenoid for the left front wheel has an electrical fault.

Brake Pressure Sensor Circuit Malfunction

The brake pressure sensor used by the ABS/stability control system has a circuit fault.

Right Front ABS Solenoid #1 Circuit Malfunction

The ABS hydraulic control unit solenoid for the right front wheel has an electrical fault.

Pump Motor Circuit Open

The ABS hydraulic pump motor circuit has an open circuit fault.

Valve Relay Circuit Malfunction

The ABS valve relay, which controls power to the hydraulic solenoid valves, has a circuit fault.
