C1107 Code: Meaning, Symptoms, Causes & Fix

Overview

Symptoms

• reduced stability control performance
• chassis warning indicator
• ABS/traction light on

Common causes

• Broken terminal inside harness affecting abs function enabled input circuit failure
• Disconnected or loose connector
• Connector pin damage/corrosion or harness stress near related components

How to diagnose C1107

1. Confirm C1107 and capture freeze-frame data with a professional scan tool.
2. Inspect wiring, connectors, and grounds related to abs function enabled input circuit failure for obvious defects.
3. Use a continuity test from module pin to component to identify opens/high resistance.
4. Check for related DTCs to identify the root-cause chain before replacing parts.
5. After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code C1107

Moderate: This code is moderate severity: the vehicle may still operate, but fault progression can increase repair cost over time.

Can you drive with C1107?

Most vehicles can be driven short-term with C1107, but postpone heavy load/highway driving until repaired.

If the warning lamp is flashing or drivability/safety is affected, avoid driving and diagnose immediately.

How to fix it (step-by-step)

1. Repair obvious wiring/connector faults first to prevent repeat parts replacement.
2. Address the root fault mode (open) in the abs function enabled input circuit failure circuit/system.
3. Apply the required relearn/adaptation procedure if specified by service information.
4. Road-test and verify C1107 remains cleared under the conditions that originally set the code.

Fix options

• Repair open circuit and secure connector lock.
• Clear corrosion and protect terminals.
• Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$240-$1200

Common mistakes when diagnosing C1107

• Replacing parts without verifying voltage, ground, and signal integrity first.
• Ignoring related stored/pending codes that indicate upstream faults.
• Skipping post-repair verification drive cycle and readiness checks.

C1107 in common vehicles

C1107 appears across makes such as Nissan, Hyundai, Kia, Volkswagen. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes C1107?

C1107 is commonly set by open faults affecting abs function enabled input circuit failure.

How much does it cost to fix C1107?

For C1107, repair costs are typically $240-$1200 depending on exact root cause, labor rates, and part quality.

Can I clear C1107 without repair?

You can clear C1107 temporarily, but the code usually returns until the underlying fault is corrected.
