C1114 — ABS Power Relay Output Short Circuit To Ground

Will C1114 clear itself?

Sometimes C1114 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

What does OBD2 code C1114 mean?

OBD2 code C1114 flags a problem with the ABS / stability control (ABS power relay output short circuit to ground). Short, gentle driving to a shop is usually possible. Common culprits: blown fuse or low voltage to the ABS module, damaged tone (reluctor) ring on the hub, faulty ABS module or pump motor.

What is the most common cause of C1114?

The most common causes are: blown fuse or low voltage to the ABS module, damaged tone (reluctor) ring on the hub, faulty ABS module or pump motor.

How do I diagnose C1114 myself?

Start with a scan: confirm C1114, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the ABS / stability control, and verify the suspect component against live data before buying parts.

How much does it cost to fix C1114?

Repair sensor wiring — $80–$250; ABS module repair or replacement — $400–$1,200; Replace a wheel speed sensor — $120–$350. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

When your scan tool displays C1114, it means the vehicle's brake control computer has detected a problem with the anti-lock braking system. Specifically, the module has identified that the ABS power relay circuit is experiencing a short to ground — current flowing where it should not. This diagnostic trouble code falls under the chassis category, which covers brakes, steering, and suspension components.

The ABS control unit constantly monitors the electrical circuits that power the pump motor, valves, and associated relays. When it senses that the relay output is shorted to ground, it sets C1114 and illuminates the warning light on your dashboard. The module typically requires multiple failure events across successive drive cycles before it will trigger this code, which helps prevent false alarms caused by temporary electrical glitches.

In addition to storing C1114, the control module saves a freeze frame — a snapshot of operating conditions at the exact moment the fault occurred. This includes engine rpm, load data, coolant temperature, and vehicle speed. Reviewing this data first gives you context about whether the problem happened during cold startup, hard braking, or specific driving conditions, which dramatically narrows your diagnostic focus.

Common Symptoms of C1114

• ABS or ESC warning lamp illuminates on the instrument cluster
• Stability control disabled message appears in the driver information display
• Brake pedal feels different — either unusually firm or exhibits pulsation during stops
• Speedometer reads incorrectly or cruise control refuses to engage
• ABS fails to activate during emergency braking, even when you press the pedal hard
• Traction control may be unavailable, particularly on low-traction surfaces

What Causes C1114

The most common source of C1114 is a faulty ABS module or pump motor assembly. Internal contacts inside the hydraulic unit can wear out, causing the relay circuit to short internally. When this happens, the module itself needs either repair or replacement.

Damage to the tone ring (also called a reluctor ring) mounted on the wheel hub is another frequent culprit. This toothed ring works with the wheel speed sensor to measure rotational speed. If it becomes contaminated with road debris, corroded, or physically damaged, it can create erratic signals that confuse the ABS module into setting C1114.

A failed wheel speed sensor can also trigger this code. When the sensor itself fails electrically or produces wildly inaccurate readings, the control unit detects the anomaly and may flag it as part of the relay output circuit problem.

Low system voltage or a blown fuse feeding the ABS module creates conditions where the module cannot operate within its designed parameters. This sometimes registers as a short-to-ground condition even though the actual problem is insufficient power.

Wiring harness damage near the wheel hubs or along the brake lines represents another possible cause. Chafed insulation, corrosion at connectors, or pins that are not fully seated can allow battery voltage or ground to reach circuits where they do not belong.

How to Diagnose C1114

Start by connecting a quality OBD2 scanner and confirming C1114 is stored in the ABS module memory. Record the freeze frame data before clearing anything — this information is your baseline for recreating the failure condition.

Check for any other trouble codes that accompany C1114. Related sensor codes or communication faults often point toward the actual root cause rather than assuming the ABS module itself has failed. Also look up technical service bulletins for your specific make and model; manufacturers sometimes publish known fixes, software updates, or recall information that applies to this particular code.

Perform a thorough visual inspection of the wiring harness and connectors associated with the ABS system. Focus on areas near the wheel hubs where the harness flexes during suspension movement. Look for damaged insulation, green corrosion deposits, or connectors that are not fully latched.

Monitor the four wheel speed sensor PID values on your scanner while driving slowly in a safe location. A faulty sensor typically drops out intermittently or shows speed readings that do not match the other three wheels.

Remove and inspect each wheel speed sensor and its corresponding tone ring. Clean any metallic debris from the ring teeth and check for cracks, missing teeth, or rust that could distort the signal.

After addressing any obvious issues, clear the code and complete a full drive cycle, including the conditions recorded in your freeze frame data. Verify that C1114 does not return.

Repair Options and Costs

Depending on what your diagnosis uncovers, here are typical repair scenarios with parts and labor at independent shop rates:

• Sensor wiring repair or connector replacement: $80–$250
• Wheel speed sensor replacement (per wheel): $120–$350
• ABS module repair or complete replacement: $400–$1,200

Total Cost to Fix C1114

Most repairs for C1114 fall somewhere between $80 and $1,200 total. The wide range reflects how different the underlying causes can be. In many cases, cleaning a corroded connector or replacing a single sensor resolves the issue at the lower end of the spectrum. Module replacement becomes necessary only when internal circuitry fails, which represents a more significant investment.

Can You Drive with C1114?

Your conventional brakes will continue functioning, so the vehicle remains driveable in the short term. However, both ABS and electronic stability control are disabled when this code is active. Stopping distances increase noticeably on wet pavement, gravel, ice, or any surface where wheel slip is likely. Drive cautiously, avoid aggressive braking maneuvers, and prioritize getting the vehicle diagnosed and repaired before relying on it for demanding conditions or long trips.
