Hi everyone,

I have a 2003 4.4 x5 and have got a lot of great information for many of you that have posted mods. Recently, I added a sub amp to my harmon Kardon amp using the helpful information in the following post http://www.xoutpost.com/articles/x5/s...ctory-amp.html I also previously added a reverse camera using another post on this forum http://www.xoutpost.com/x5-e53-forum/...reverse+camera. After adding the sub amp I noticed that my air bad sensor light lit up. Having to get it serviced I also asked if they could reset te air bag warning light as I assumed I triggered it by disconnecting the battery leads to add the direct main electrical feeds for the sub amp. However, the technician said they could not clear the error as it was a permanent error due to "battery positive isolation resistance too high". Apart from disconnecting everything and seeing if the warning light will reset and going through a round of trial and error to see which connecting is causing the problem, is there anyone who has experianced this or know what the problem may be? Is there a problem with taking direct feeds from the battery to power the sub amp/ camera ( problem was not there when the camera was first installed but not sure if in combination with the sub amp if this has contributed to the problem)?

Hope somone can help, thanks.

John
