This summary uses the existing diagnostic information shown in full below.
The car's computer is having trouble getting a signal from the sensor that tells how fast the front left wheel is moving.
This code indicates that the voltage from the left front wheel speed sensor is lower than expected, which could affect the car's anti-lock braking system (ABS).
The C0653 code is triggered when the ABS module detects a low voltage signal from the left front wheel speed sensor B circuit. This sensor is crucial for monitoring wheel speed and ensuring proper ABS function.
• ABS warning light on
• Inoperative ABS system
• Unusual braking behavior
• Faulty wheel speed sensor
• Damaged wiring or connectors
• Faulty ABS control module
ABS: Anti-lock Braking System
OBD-II: On-Board Diagnostics, second generation
• Use an OBD-II scanner to confirm the code.
• Inspect the left front wheel speed sensor and its wiring.
• Test the sensor's voltage output with a multimeter.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring or connectors.
• Replace the ABS control module if necessary.

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regularly inspect wheel speed sensors.
• Ensure wiring is intact and free from damage.
• Keep ABS components clean and dry.
Sensor Issue
• Avoid hard braking until the issue is fixed.
• Drive cautiously, especially in wet conditions.
Check with the vehicle manufacturer for specific warranty coverage related to ABS components.
This code has been commonly reported in vehicles with high mileage or those exposed to harsh conditions.
Moderate – While the vehicle can still be driven, the ABS system may not function properly, which can affect braking performance.
Driving with a malfunctioning ABS can increase the risk of accidents, especially in slippery conditions.
• Vehicle must be in motion.
• ABS system must be active.
The left front wheel speed sensor is located near the wheel hub of the front left wheel.
Q: Can I drive with a C0653 code?
A: Yes, but the ABS system may not work, so be cautious, especially in wet or slippery conditions.
Q: How do I reset the ABS light after fixing the issue?
A: Use an OBD-II scanner to clear the code, or disconnect the battery for a few minutes.
Pro · Four-system diagnostics
A handheld scanner aimed at engine, transmission, ABS, and airbag diagnostic work.
Chassis and ABS faults usually need a scanner that can read brake-system data directly.
