Just about every vehicle built over the last 30 years incorporated some form of Body Control Module (BCM) or in the case of our Chrysler minivan it's called a TIPM.
These computers handle all of the vehicles non power train electrical systems, and when something goes wrong with one it can mean big diagnostic time and expensive parts.
There are situations where a bad circuit within one of these computers can be worked around using a simple external relay.
Here's how we got the headlights on this Mopar to function normally and how you can apply this concept to nearly any electrical system on any vehicle.
