What Does C1262 Mean?
The ABS module has detected a malfunction in the left front outlet (dump) valve solenoid. This solenoid opens to release hydraulic pressure from the left front brake caliper during ABS cycling. With this valve malfunctioning, the ABS cannot properly reduce brake pressure on the left front wheel, which may cause that wheel to lock during ABS operation.
Common Causes
40%
Failed left front outlet valve solenoid inside the ABS hydraulic modulator
25%
Internal wiring fault between ABS module driver and outlet valve solenoid
20%
Contaminated or degraded brake fluid causing the valve to stick mechanically
10%
ABS module electronic driver circuit failure for the outlet solenoid
5%
Poor ABS module ground connection affecting solenoid drive current
Diagnostic Steps
1
Using bi-directional scan tool control, command the left front outlet valve solenoid and listen for actuation clicks at the ABS modulator unit.
2
Measure outlet solenoid resistance at the ABS module connector — typical is 3-6 ohms. An open circuit or values significantly outside this range indicate a failed solenoid coil.
3
Check ABS module power and ground integrity — battery voltage on power pins, less than 0.5 ohms on ground circuit. Poor grounds can prevent proper solenoid actuation.
4
Inspect brake fluid for contamination, discoloration, or moisture content. Old, contaminated fluid is a leading cause of internal ABS valve sticking.
5
If electrical tests pass, perform a complete ABS brake fluid flush and bleed procedure. If the code returns, the modulator valve is mechanically stuck and the ABS modulator assembly will need replacement.

The most common cause of C1262 (Left Front Outlet Valve Solenoid Malfunction) is: Failed left front outlet valve solenoid inside the ABS hydraulic modulator
Typical repair costs for C1262 range from $200 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The ABS cannot properly release pressure on the left front brake during anti-lock cycling. This could cause the left front wheel to lock during hard braking on slippery surfaces. Normal braking is unaffected. Drive carefully and avoid aggressive braking until repaired.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to C1262 to identify the root cause.
