C0060 - Left Front ABS Solenoid #1 Circuit Malfunction

🔹 DTC Code: C0060 – Left Front ABS Solenoid #1 Circuit Malfunction

🔸 Meaning

C0060 indicates a problem in the left front ABS solenoid valve circuit.
This solenoid is part of the ABS hydraulic unit and is controlled by the EBCM (Electronic Brake Control Module).

---

🔸 Description

The inlet and outlet valve solenoids receive battery voltage when the ignition is ON.
The EBCM controls these solenoids by switching the circuit ON and OFF when required during braking.

👉 Simple understanding:

• Brake applied → EBCM activates solenoid
• Solenoid controls brake pressure at the wheel

---

🔸 Possible Causes

• Damaged or open wiring in the circuit
• Short circuit to ground or battery
• Faulty ABS solenoid valve
• Defective EBCM (rare case)
• Corroded connectors

---

🔸 Symptoms

• ABS warning light ON
• Loss of ABS function
• Wheel may lock during hard braking
• Brake performance may feel abnormal

---

🔸 Diagnosis Tips

• Check wiring continuity
• Inspect connectors for corrosion or looseness
• Measure voltage supply to solenoid
• Scan ABS live data using OBD tool

---

🔸 Repair Solutions

• Repair or replace damaged wiring
• Clean or fix connectors
• Replace faulty ABS solenoid / hydraulic unit
• Reprogram or replace EBCM if required

🔸 Meaning

U0073 means the CAN Bus communication network is down or not working properly.
Modules like ABS, ECM, BCM cannot communicate with each other.

---

🔸 Description

Modern vehicles use a CAN Bus network to share data between different control modules.
If this network fails, multiple systems may stop working or show errors.

---

🔸 Possible Causes

• CAN High / CAN Low wire damage
• Short circuit or open circuit
• Loose or corroded connectors
• Faulty control module blocking communication
• Low battery voltage

---

🔸 Symptoms

• Multiple warning lights ON (ABS, Engine, etc.)
• Communication error in scanner
• Vehicle may not start (in some cases)
• Loss of multiple electronic functions

---

🔸 Diagnosis Tips

• Check CAN wiring (twisted pair wires)
• Measure resistance (approx. 60 ohms in healthy network)
• Disconnect modules one by one to find faulty unit
• Use professional diagnostic scanner

---

🔸 Repair Solutions

• Repair CAN wiring
• Fix connector issues
• Replace faulty module causing network failure
• Ensure proper battery voltage

---

🔹 Conclusion

Both C0060 and U0073 are important fault codes related to vehicle safety and communication systems.

• C0060 affects ABS braking performance
• U0073 affects overall vehicle communication

👉 Proper diagnosis is very important before replacing any parts.

U0073 Meaning 

C0060 Description The bay and outlet valve solenoid circuits are provided with battery power when the start is in the ON position. The electronic brake control module (EBCM) controls the valve capacities by establishing the circuit when important.
