Blown fuse #21 BTSI 03 C5
Fuse 21 BTSI keeps blowing on my 03 C5. When it blows the message "Check tire pressure monitoring system" appears. Unsure of what direction to take with this. When I originally checked the fuse it had been replaced with a 15 amp instead of the 10 amp. Anyone have some insight into this problem?

Is it Auto trans?
List of possibilities causing the short:
1.) Inside Rear View Mirror
2.) Park/ Neutral Switch ( If Auto)
3.) Reverse Light Switch ( If Man)
4.) Wiring short within the brown wire coming from the fuse box (Pin B7)
5.) Fuse Block Itself
Disconnect one by one until you see the short has gone away.

Thanks for the help. I replaced the reverse light switch and all is good.
