Installation and Post-Install Notes
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the driver’s side dashboard near the steering column. While the unit is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on after installation. This requires a professional-grade scan tool. Additionally, a Brake Pedal Position Relearn might be necessary. Always consult a factory service manual for your specific vehicle if you are unsure.
Frequently Asked Questions
Does this BCM need to be programmed by a dealer?
No. This Body Control Module comes pre-programmed to your vehicle’s VIN. Simply provide your VIN at checkout, and it will arrive ready for a plug-and-play installation, saving you a trip to the dealership.
What is the most common sign of a bad BCM in a Yukon?
One of the most common signs is a combination of unrelated electrical issues happening at once, such as power locks failing while the radio acts erratically. This indicates a problem with the central controller rather than individual components.
Is this a difficult part to replace myself?
For most DIY mechanics, the replacement is simple. The BCM is usually located under the dash and is held in by a few bolts or clips. The entire process often takes less than 30 minutes. However, post-installation procedures like an airbag system sync may require a professional scan tool.
What happens if I don’t replace a failing BCM?
Ignoring a failing BCM can lead to worsening electrical problems, including potential no-start situations if the security system is affected. It can also cause safety systems like airbags and brake lights to malfunction, making it a critical repair.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old module back to us, which simplifies the replacement process for you.
