B255F 2014 Chevrolet Silverado Code - Interior Door Handle Backlight Circuit

The code B255F indicates a problem with the interior door handle backlight circuit, such as a malfunction or fault in the wiring, bulb, or module controlling the backlight.

The most common symptom is that one or more interior door handle lights do not illuminate properly or at all.

Common causes include a burned-out bulb, damaged wiring, a faulty door module, or a poor electrical connection in the backlight circuit.

Yes, this is not a critical issue and doesn’t affect the drivability of the vehicle, but it may reduce visibility of the door handle area in low-light conditions.

Start by inspecting the door handle backlight for signs of damage or a burned-out bulb. Then check the wiring and connectors for continuity or corrosion. A scan tool can help diagnose the specific circuit fault.

It is less likely, but it’s worth checking the fuse related to the interior lighting to rule out a simple cause before performing more extensive diagnostics.

Repair or replace the faulty bulb, fix damaged wiring or connectors, or replace the door module if it’s determined to be the source of the problem.

The cost varies depending on the exact cause. A replacement bulb may cost less than $20, while repairing wiring or replacing a door module could cost $100–$300 in parts and labor.

You can clear the code with a scan tool, but it will likely return if the underlying issue is not resolved.

For simple fixes like replacing a bulb, you may not need a mechanic. However, for more complex issues like wiring repairs or module replacement, professional assistance is recommended.
