Can a bad battery cause electrical codes?

Yes, a weak or failing battery can cause voltage drops that affect various modules and sensors, potentially triggering multiple codes. Always check battery health and charging system first.

How much do electrical repairs cost?

Electrical repairs range from $75 for a simple connector fix to $400+ for wiring harness repairs or module replacements. ECM/PCM replacement can cost $500-$1,500 including programming.

B0260

Auto-Dimming Mirror Circuit Malfunction

Lowelectrical

Overview

The B0260 code indicates that the body control module has detected a auto-dimming mirror circuit malfunction 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

Check Engine Light (MIL) illuminated
Multiple warning lights on dashboard
Battery draining overnight
Vehicle going into limp mode or reduced power

Common Causes

Faulty engine control module (ECM/PCM)
Water damage to electrical connectors
Faulty alternator/generator
Short or open circuit in wiring

Diagnosis Steps
