C0015 Right Front Outlet Control

Check engine lightUsually off
EmissionsNot relevant
Drive cycleNot required
Limp modePossible

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.

Likely causes

Outlet valve coil open or shorted
Harness or connector corrosion
Internal hydraulic modulator fault

Symptoms

  • ABS warning lamp on
