Is it safe to drive with this code?

You can typically drive the vehicle as normal braking function often remains intact, though ABS and traction control will be disabled. Exercise additional caution in wet or slippery conditions where ABS would normally assist, and avoid heavy braking situations where possible. See our site disclaimer for further guidance.

This may affect your MOT result if the ABS warning light is illuminated at the time of the test, as a permanently lit ABS lamp can constitute a Major defect under current guidelines. What matters is the state of warning lamps during inspection—see our disclaimer for details.

Roughly how much does it cost to fix?

Costs vary widely depending on the root cause. If it's a wiring or connector issue, you may face low to mid three-figure sums for diagnosis and repair. Should the ABS hydraulic control unit require replacement, expect mid three-figure to four-figure costs, especially at main dealers where coding and calibration are included. Independent specialists offering remanufactured or repaired ABS units can often reduce costs significantly.

Can the ABS module be repaired instead of replaced?

In many cases, yes—specialist workshops in the UK offer ABS module repair services that rebuild internal solenoid valves and circuit boards, often at a fraction of the cost of a new unit. Repairs commonly range from low to mid three-figure sums and typically include testing and warranty, though turnaround may involve postal service.

C0152

Chassis

Right Rear ABS Solenoid Valve Relay Circuit Stuck Open

The ABS control module has detected that the relay circuit controlling the right rear anti-lock brake solenoid valve may be stuck in the open position, which can prevent proper modulation of brake pressure to that wheel.

ⓘ Information only. This page provides general educational information about fault code C0152. We do not assess the urgency or safety implications of any specific fault. That requires in-person diagnosis by a qualified mechanic. Full terms.

Recommended next steps

Whether a fault is urgent, drivable, or routine depends entirely on the cause on a specific vehicle, and that can only be determined by a qualified mechanic with diagnostic equipment. If a warning light is illuminated, the most reliable next step is professional diagnosis.

What does C0152 mean?

C0152 is a Chassis (ABS, traction control, steering) fault code. It indicates: Right Rear ABS Solenoid Valve Relay Circuit Stuck Open.

This is a standardised OBD-II code. The technical definition is the same regardless of the make or model of vehicle, although specific causes and symptoms can vary between vehicles.

About ABS / ESP codes

Codes in this category relate to the anti-lock braking system (ABS) and electronic stability control (ESP/ESC). These systems share wheel speed sensors, hydraulic modulators, and a common control module. Faults here usually disable ABS pulse braking and stability control assistance, but standard hydraulic brakes continue working normally.
