Abs Control Module Internal Failure
This code indicates a failure within the ABS control module.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The ABS control module isn't working right; it can't properly control the anti-lock braking system because something's failed inside it.
What the computer is actually seeing
The ABS module detects an internal fault that prevents it from operating correctly, like a short circuit or faulty internal component.
What a healthy reading looks like
Normal operational voltages for the ABS module should be between 10-15 volts when powered and less than 0.5 volts for signal grounds while in active mode.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check battery voltage: should be between 12.5-14.5 volts with the engine running. If not, address battery or charging issues first.
- 2Inspect the ABS module wiring and connectors for damage or corrosion; repair or replace as needed.
- 3Using a scan tool, clear the code and retest. If it returns immediately, the ABS module likely needs replacement.
- 4Check for related codes (C1310, C1311) for additional insights; address those as needed.
Common causes
- Short circuits in the wiring harness
- Corrosion or damaged connectors
- Faulty ABS control module
