C1614 on Hyundai vehicles indicates abs control module self-test failed. Au7o has documented this code across 1 Hyundai model — most commonly on Equus. 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. Typical repair costs on Hyundai range from $800 to $3,000, depending on the specific model and root cause.

Common Causes of C1614

  • •Internal fault within the ABS control module
  • •Corrupted module software/calibration
  • •Low or unstable supply voltage to the module
  • •Poor power or ground connections at the module
  • •Moisture/corrosion intrusion into the module
  • •Damaged module connector pins
  • •Faulty 12V battery or charging system

  • Rear Air Suspension Strut Leak and Compressor Failure2011-2016

    The Hyundai Equus flagship sedan uses rear air suspension for luxury ride quality. The air struts develop leaks at the rubber air bladder, particularly at the crimp ring seals, typically after 5-7 years regardless of mileage. The air compressor runs excessively to compensate for leaking struts, leading to compressor overheating and premature failure. The vehicle sags at the rear when parked overnight as air slowly escapes.
