Can a dead battery cause body electrical codes?

Yes, low battery voltage is a very common cause of body electrical codes. When voltage drops, body control modules can store false codes. Always check battery health first before replacing components.

How much does a body control module replacement cost?

BCM replacement typically costs $300-$800 including programming. However, many body electrical codes are caused by simple wiring or fuse issues that cost much less to repair.

B0144

Power Mirror Fold Motor Circuit - Right

Lowelectrical

Overview

The B0144 code indicates that the body control module has detected a power mirror fold motor circuit - right condition. This relates to the vehicle's body electrical systems, which control comfort, convenience, and safety features. When this code is stored, the affected system or component may not operate correctly, potentially impacting safety or comfort features.

Symptoms

SRS indicator light stays on or flashes
