How do I fix code B2625?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Cost of diagnosing the B2625 code
The cost of diagnosing the B2625 code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
B2625 Description
The Body Control Module (BCM) receives a variable voltage signal from the Instrument Panel (I/P) dimmer switch requesting to illuminate the dimming lamps to a desired intensity. When this occurs, the BCM directly sends a Pulse Width Modulated (PWM) voltage based on the I/P dimmer switch position on the LED dimming supply circuit, instrument panel lamps dimming control circuit, and the instrument panel lamps dimming supply voltage circuit.
Voltage for the LED dimming supply circuit, instrument panel lamps dimming control circuit, and the instrument panel lamps dimming supply voltage circuit is from the TBC 2 A fuse in the I/P fuse block directly through the BCM to these circuits.
