Default BCM issues

Hello, I'm a first time jag owner and I have an issue, when trying to jump my car my little brother reversed the polarity on the battery and it messed with the BCM so now it won't send a signal to the relay to start the engine, do I need to buy just one BCM or replace both of them?

Devin,

OOPS

You dont tell us too much as to what year etc the beast is.

None of the "Series" cars in here had a BCM.

The XJ6 Naming was used for 40+ years and makes it a tad confusing.

When brother is dealt with, and the beast is sorted, please do an Intro in the New Members Area.

Tell us the year, and we will help you, beers be at Brothers cost.
