C1107 — ABS Function Enabled Input Circuit Failure #

Note: The code description may vary depending on the manufacturer. Always refer to OEM documentation for precise wording.

• ABS Function Enabled Input Circuit Failure (Generic/OEMs)
• ABS Enable Input Circuit Malfunction (Nissan)
• ABS Function Circuit Error (Chrysler, Dodge, Jeep)

Summary of code C1107 #

The diagnostic trouble code C1107 indicates a problem detected in the ABS function enabled input circuit. The Anti-lock Braking System (ABS) prevents wheel lock-up during hard braking for better control. This code is triggered when the ABS control module detects an abnormal signal, open, or short in the wiring related to the ABS enable input. The issue may originate in the wiring, connectors, or associated components, and often affects the ABS system’s ability to operate as designed. Prompt attention is recommended, as braking performance can be compromised.

Common symptoms for code C1107 #

Drivers may notice several warning signs when the C1107 code is present. The most frequent symptom is the illumination of the ABS warning light on the dashboard. In many cases, the ABS system may be disabled, causing the vehicle to revert to standard (non-ABS) braking. Some drivers report a noticeable change in braking feel or performance, especially during emergency stops. Rarely, traction or stability control systems may also be impacted, as these often rely on ABS functionality.

• ABS warning light illuminated
• ABS system disabled or inoperative
• Loss of traction/stability control functions (in some vehicles)
• Longer stopping distances under hard braking
• No noticeable symptoms under normal driving in some cases

Most probable causes for code C1107 #

There are several potential causes for a C1107 code. They typically range from simple wiring issues to failed components within the ABS system. The most common are electrical faults, but mechanical issues can sometimes play a role. Below, causes are listed in order of likelihood:

1. Damaged or corroded wiring/connectors in the ABS enable input circuit
2. Faulty ABS enable switch or input device (if equipped)
3. Faulty ABS control module
4. Blown fuse related to ABS input circuits
5. Water intrusion in ABS harness/connectors
6. Poor ground connection to the ABS module

Step-by-step diagnostic procedure for DTC C1107 #

A methodical approach is key to accurately diagnosing C1107. Begin with a visual inspection and progress toward more technical tests as needed. Always follow safety procedures when working on brake systems.

• 1. Scan for additional codes: Use an OBD-II/EOBD scanner to check for other related trouble codes.
• 2. Inspect ABS warning light: Confirm if the ABS lamp is on and note any other dashboard indicators.
• 3. Visually inspect wiring and connectors: Look for damaged, frayed, or corroded wires and connectors on the ABS input circuit.
• 4. Check fuses: Test all ABS-related fuses with a multimeter.
• 5. Test ABS enable input switch: If equipped, verify correct function and signal using a multimeter or scan tool.
• 6. Perform continuity and resistance tests: Check the ABS input circuit between the switch (if present) and the ABS module for open or short circuits.
• 7. Inspect ABS module ground: Ensure the module has a solid ground connection.
• 8. Test ABS control module: If all else passes, suspect a failed ABS control module—further testing may require advanced diagnostic tools or OEM procedures.

Possible repairs for code C1107 #

Repair options for C1107 depend on the specific root cause. Most repairs involve restoring proper electrical connectivity or replacing a faulty component. After each repair, clear the code and road test the vehicle to ensure the ABS system is restored.

• Repair or replace damaged wiring/connectors in the ABS input circuit
• Clean corroded connectors and apply dielectric grease
• Replace a faulty ABS enable input switch (if present)
• Replace blown ABS-related fuses
• Address water intrusion—dry out affected areas and reseal as needed
• Restore or repair poor ground connections to the ABS module
• Replace the ABS control module if confirmed faulty (last resort)

Is it safe to drive with code C1107? #

Driving is generally possible but not recommended with code C1107 present. The ABS system may be disabled, meaning you will not have anti-lock functionality during emergency braking or slippery conditions. Standard braking will remain, but stopping distances could increase and vehicle control may be compromised. For your safety and others’, have your vehicle inspected and repaired as soon as possible.

Vehicles most commonly affected by code C1107 #

While C1107 is a generic ABS code, it appears more frequently in certain makes and models. Vehicles from the following manufacturers are commonly reported with this code, though it can occur in others:

• Nissan (Altima, Sentra, Maxima, Pathfinder)
• Chrysler, Dodge, Jeep (300, Charger, Grand Cherokee, Ram trucks)
• Hyundai and Kia (various models)
• Mitsubishi
• Renault

Common mistakes & best practices for code C1107 #

Mistakes in diagnosing C1107 often stem from skipping basic checks or replacing expensive components prematurely. Following best practices can save time, money, and prevent unnecessary repairs.

• Overlooking simple wiring faults or corroded connectors
• Not checking all related fuses before replacing parts
• Assuming the ABS module is faulty without proper testing
• Ignoring OEM-specific diagnostic procedures
• Failing to clear codes and road test after repairs

Quick FAQ for code C1107 #

Have more questions? Here are fast answers to common concerns about C1107:

Q: Can I clear the C1107 code and keep driving?
A: You can clear the code with a scan tool, but if the underlying issue isn’t fixed, the code (and ABS light) will return—address the root cause for safe operation.

Q: Will my ABS work with C1107 present?
A: Usually not. The ABS system is typically disabled when this code is active, reverting your vehicle to standard braking only.

Q: Does C1107 mean I need a new ABS module?
A: Not always. Most cases are due to wiring or connection issues—check these before replacing expensive parts.
