C0010 code meaning
Left Front Inlet Control
What C0010 means
Covers the left front inlet (apply) solenoid valve of the ABS hydraulic modulator. During ABS, traction or stability control the module closes this valve to isolate the left front brake circuit from the master cylinder and hold wheel pressure, then opens it to let pressure back in. The module checks the coil for opens, shorts and out-of-range resistance and monitors valve response. GM documents code C0010 (sub-type .5A) setting in the electronic brake control module of 2018-2019 Equinox, Terrain, Envision and Canyon, where it could store falsely and was under engineering review. A fault disables ABS and related functions; the red brake or amber ABS lamp illuminates and conventional braking remains.

Symptoms of C0010
- ABS warning lamp on
- ABS and stability control disabled
- Normal braking retained
Common causes of C0010
- Most likelyInlet valve coil open or shorted
- PossibleBrake control module fault or false setting
- Less likelyHarness or connector corrosion
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note C0010 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 C0010
What does C0010 mean?
C0010 means "Left Front Inlet Control". Covers the left front inlet (apply) solenoid valve of the ABS hydraulic modulator. It is a generic code, so it means the same on every make.
Is it safe to drive with C0010?
Drive gently and only to a workshop. With C0010 the car can go into limp mode (reduced power) to protect itself.
Will C0010 fail an emissions test?
C0010 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 C0010 to fix?
Difficulty: workshop only. A typical repair takes 1.5 to 4 hours of work. This is a job for a workshop.
Will C0010 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
