C0015 code meaning
Right Front Outlet Control
What C0015 means
Covers the right front outlet (release) solenoid valve of the ABS hydraulic modulator, the release counterpart to inlet valve C0014. It opens to dump brake fluid from the right front caliper into the low-pressure accumulator so wheel pressure can fall during an ABS or stability cycle, then closes for reapply. The module monitors the coil circuit for opens, shorts and out-of-range resistance and checks valve response. A confirmed fault disables ABS, traction and stability control and sets the ABS warning lamp while base hydraulic braking stays available. No manufacturer documents this code publicly; the inlet/outlet pair per wheel is described in NHTSA's brake safety study and in a pump patent for ABS/ESC units.

Symptoms of C0015
- ABS warning lamp on
- ABS and stability control disabled
- Normal braking retained
Common causes of C0015
- Most likelyOutlet valve coil open or shorted
- PossibleHarness or connector corrosion
- Less likelyInternal hydraulic modulator fault
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0015 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about C0015
What does C0015 mean?
C0015 means "Right Front Outlet Control". Covers the right front outlet (release) solenoid valve of the ABS hydraulic modulator, the release counterpart to inlet valve C0014. It is a generic code, so it means the same on every make.
Is it safe to drive with C0015?
Drive gently and only to a workshop. With C0015 the car can go into limp mode (reduced power) to protect itself.
Will C0015 fail an emissions test?
C0015 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is C0015 to fix?
Difficulty: workshop only. A typical repair takes 1.5 to 4 hours of work. This is a job for a workshop.
Will C0015 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
