C1136 Code: Meaning, Symptoms, Causes & Fix

Overview

Code C1136 indicates a fault in Gear Select position short to ground, typically within ABS/chassis dynamics and brake control.

Symptoms

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

Common causes

Electrical fault in the affected circuit affecting gear select position short to ground
Control module logic or calibration issue
Connector pin damage/corrosion or harness stress near related components

How to diagnose C1136

Confirm C1136 and capture freeze-frame data with a professional scan tool.
Inspect wiring, connectors, and grounds related to gear select position short to ground for obvious defects.
Use freeze-frame and live data to isolate whether the issue is electrical, mechanical, or control logic.
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 C1136

Low: This code is low to moderate severity in most cases, but diagnosis is still recommended to avoid recurring warnings.

Can you drive with C1136?

The vehicle is often drivable with C1136, but plan a repair window to prevent repeat faults.

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 (generic) in the gear select position short to ground circuit/system.
Apply the required relearn/adaptation procedure if specified by service information.
Road-test and verify C1136 remains cleared under the conditions that originally set the code.

Fix options

Clear code and confirm through drive cycle.
Test component operation and replace if faulty.
Clear DTCs and verify with live data and completed drive cycle.

Typical repair cost

$120-$500

Common mistakes when diagnosing C1136

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.

C1136 in common vehicles

C1136 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 C1136?

C1136 is commonly set by generic faults affecting gear select position short to ground.

How much does it cost to fix C1136?

For C1136, repair costs are typically $120-$500 depending on exact root cause, labor rates, and part quality.

Can I clear C1136 without repair?
