• C0602
• C0603
This code means that the car's computer is having trouble communicating with one of the wheels. It's like when a walkie-talkie isn't working properly and you can't hear the other person.
C0601 indicates a malfunction in the wheel speed sensor's communication circuit.
The C0601 code is triggered when the vehicle's onboard computer detects a fault in the communication circuit of one of the wheel speed sensors. This sensor is crucial for the anti-lock braking system (ABS) and traction control system (TCS) to function properly.
• Inspect the wheel speed sensor and its wiring for damage.
• Check the connectors for corrosion or loose connections.
• Use a diagnostic scanner to verify the fault and pinpoint the affected sensor.
• Replace the faulty wheel speed sensor.
• Repair or replace damaged wiring or connectors.
• Replace the ABS control module if necessary.
• OBD-II scanner
• Multimeter
• Socket set

• Regularly inspect wheel speed sensors and wiring.
• Avoid driving through deep water that can damage sensors.
• Ensure proper maintenance of the ABS system.
Sensor Issue
• Have the vehicle inspected by a professional if the ABS light is on.
• Avoid hard braking until the issue is resolved.
• Do not ignore the warning lights as they are crucial for vehicle safety.
Check with the vehicle manufacturer for specific warranty coverage on ABS components.
C0601 is a common code in vehicles with ABS systems, often related to sensor or wiring issues.
Moderate – It affects vehicle safety systems, so it should be addressed promptly.
Driving with a malfunctioning ABS can increase the risk of accidents. Ensure repairs are made by a qualified technician.
• Vehicle must be driven to simulate wheel speed.
• Diagnostic scanner connected to the OBD-II port.
The wheel speed sensor is located near the wheel hub assembly on each wheel.
Q: Can I drive with code C0601?
A: It's not recommended as it affects the ABS and traction control, which are important for safety.
Q: How can I reset the ABS light?
A: Fix the underlying issue first, then clear the code with an OBD-II scanner.
