1 vehicles · 1 makes · $800-$3,000 repair
Most Reported On
C1614 is an OBD-II diagnostic trouble code meaning “ABS Control Module Self-Test Failed.” This code means the ABS control module failed its own internal self-test. Each time the system powers up (and periodically), the ABS module checks its internal circuitry, memory, and processing to confirm it can operate safely; this code is set when that self-check fails. It usually indicates an internal hardware or software fault within the module rather than an external sensor problem. ABS and related traction/stability features will be disabled while normal braking continues, and the module often must be repaired or replaced. This code is most commonly reported on 2011-2016 Hyundai Equus, with repair costs ranging from $800 to $3,000.
