C1250 Code: Meaning, Symptoms, Causes & Fix

Overview

Code C1250 indicates a fault in ABS Inlet Valve Coil LR Circuit Failure, typically within ABS/chassis dynamics and brake control.

Symptoms

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

Common causes

Disconnected or loose connector affecting abs inlet valve coil lr circuit failure
Broken terminal inside harness
Connector pin damage/corrosion or harness stress near related components

How to diagnose C1250

Confirm C1250 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to abs inlet valve coil lr circuit failure for obvious defects.
Use a continuity test from module pin to component to identify opens/high resistance.
Check for related DTCs to identify the root-cause chain before replacing parts.
After repair, clear codes and confirm readiness monitors complete without recurrence.

Severity of code C1250

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

Can you drive with C1250?

Most vehicles can be driven short-term with C1250, 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)

Repair obvious wiring/connector faults first to prevent repeat parts replacement.
Address the root fault mode (open) in the abs inlet valve coil lr circuit failure circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify C1250 remains cleared under the conditions that originally set the code.

Fix options

Repair open circuit and secure connector lock.
Restore continuity and verify pin tension.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$240-$1200

Common mistakes when diagnosing C1250

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.

C1250 in common vehicles

C1250 appears across makes such as BMW, Mercedes-Benz, Audi, Volvo. Failure patterns differ by platform: wiring routes, software calibration, and component supplier revisions can change root cause.

Frequently asked questions

What causes C1250?

C1250 is commonly set by open faults affecting abs inlet valve coil lr circuit failure.

How much does it cost to fix C1250?

For C1250, repair costs are typically $240-$1200 depending on exact root cause, labor rates, and part quality.

Can I clear C1250 without repair?

You can clear C1250 temporarily, but the code usually returns until the underlying fault is corrected.
