What Does C0075 Mean?
This code indicates the ABS control module has detected an electrical fault in the right front wheel's second hydraulic solenoid valve circuit. The solenoid controls brake fluid pressure modulation during anti-lock braking events. The control module detected an open circuit, short circuit, or excessive resistance in the solenoid winding or its control circuit, preventing proper ABS operation on the right front wheel.
Safety Warning
The vehicle is unsafe to drive in emergency braking situations as the right front wheel will not have anti-lock braking capability, potentially causing loss of steering control and extended stopping distances. The ABS warning light will be illuminated and normal braking function may be degraded. Repair immediately.
Common Causes
45%
Faulty ABS hydraulic control unit (HCU) with internal solenoid valve failure
30%
Damaged wiring harness or corroded connector between ABS module and hydraulic unit
15%
Faulty ABS control module with failed solenoid driver circuit
10%
Water intrusion or corrosion inside the ABS hydraulic unit causing solenoid coil damage
Diagnostic Steps
1
Perform visual inspection of the ABS hydraulic control unit and all wiring harnesses for physical damage, corrosion, moisture intrusion, or chafed wires, paying special attention to connectors at the HCU
2
Using a digital multimeter, measure the resistance of the right front solenoid #2 circuit at the ABS hydraulic unit connector (typical specification: 2-6 ohms depending on manufacturer; consult service data for exact values)
3
Check for continuity and resistance in the wiring harness between the ABS control module and the hydraulic unit solenoid connector, ensuring no opens, shorts to ground, or shorts to power exist
4
Monitor solenoid activation commands using advanced scan tool bi-directional controls to verify the ABS module can command the solenoid and observe current draw (typical: 1-3 amps during activation)
5
If wiring and resistance tests pass specification, replace the ABS hydraulic control unit as the solenoid valve is likely internally failed; if resistance is out of specification at the module connector, replace the ABS control module
6
After repairs, clear codes, perform a test drive with multiple ABS activation events on safe surfaces, and verify the code does not return and ABS functions properly

The most common cause of C0075 (Right Front ABS Solenoid #2 Circuit Malfunction) is: Faulty ABS hydraulic control unit (HCU) with internal solenoid valve failure
Typical repair costs for C0075 range from $400 to $1,800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
