C0060 and C0065: Left Front ABS Solenoid #1 and #2 Circuit Malfunction

DTC error codes are diagnostic trouble codes that indicate a problem with the vehicle’s system or components. They are usually displayed on the dashboard or scanned by a code reader. In this article, we will focus on two specific DTC error codes: C0060 and C0065. These codes are related to the anti-lock brake system (ABS) solenoid circuits of the left front wheel.

What is an ABS Solenoid Circuit?

An ABS solenoid circuit is a part of the ABS system that controls the brake fluid pressure to each wheel. The ABS system prevents the wheels from locking up during hard braking, which can cause skidding and loss of control. The ABS solenoid circuit consists of an inlet valve solenoid and an outlet valve solenoid, which are electrically controlled by the electronic brake control module (EBCM). The EBCM monitors the wheel speed sensors and adjusts the brake fluid pressure accordingly.

What Do These Codes Mean?

C0060 - Left Front ABS Solenoid #1 Circuit Malfunction

It is a DTC error code that means there is a malfunction in the left front ABS solenoid #1 circuit. This circuit is responsible for the inlet valve solenoid of the left front wheel. The inlet valve solenoid allows or blocks the brake fluid from entering the wheel cylinder. If there is a problem with this circuit, the EBCM may not be able to regulate the brake fluid pressure properly.

C0065 - Left Front ABS Solenoid #2 Circuit Malfunction

This is a DTC error code that means there is a malfunction in the left front ABS solenoid #2 circuit. This circuit is responsible for the outlet valve solenoid of the left front wheel. The outlet valve solenoid allows or blocks the brake fluid from leaving the wheel cylinder. If there is a problem with this circuit, the EBCM may not be able to release the brake fluid pressure properly.

What are the Possible Causes of C0060 and C0065?

There are several possible causes of these DTC error codes, such as:

• Faulty left front ABS solenoid
• Damaged or corroded wiring harness or connectors
• Shorted or open circuit
• Poor electrical connection
• Faulty EBCM

What are the Symptoms of C0060 and C0065?

Some of the symptoms that may indicate these DTC error codes are:

• ABS warning light on
• Check engine light on
• Reduced braking performance
• Increased stopping distance
• Unusual noise or vibration from the brakes

How to Fix C0060 and C0065?

To fix these DTC error codes, you need to perform some diagnostic steps, such as:

• Scan the vehicle with a code reader and record the freeze frame data
• Clear the codes and test drive the vehicle to see if they reappear
• Visually inspect the left front ABS solenoid, wiring harness, and connectors for any damage or corrosion
• Check for continuity and resistance in the left front ABS solenoid circuit using a multimeter
• Check for voltage and ground in the left front ABS solenoid circuit using a test light
• Replace or repair any faulty components as needed
• Re-scan the vehicle and verify if the codes are cleared

Conclusion

C0060 and C0065 are DTC error codes that indicate a problem with the left front ABS solenoid circuits. These circuits control the brake fluid pressure to the left front wheel and prevent it from locking up during hard braking. If these codes are present, you may experience reduced braking performance, increased stopping distance, or abnormal noise or vibration from the brakes. To fix these codes, you need to diagnose and repair any faulty components in the left front ABS solenoid circuit. By doing so, you can ensure your vehicle’s safety and performance on the road.
