2009 H3 Base 3.7L, can somebody check the underhood fusebox for FUSE 32 RVC VSENSE+ 10A. I just want to know if the fuse is installed, mine is missing. I don't have any weird problems on the 3, or any codes from my Tech 2. Just found out when i'm installing the windshield washer heater. Thanks!

Circuit/System Description
The generator battery control module (GBCM) monitors the battery voltage for precision electrical power management. The GBCM monitors both the RVC PWR B+ circuit and the RVC VSENSE B+ circuit to precisely determine system voltage. If the RVC VSENSE B+ circuit is 1.5 volts less than the RVC PWR B+ circuit for 7 seconds, then DTC B1390 will set.

I have a 2009 3.7L that seems to go wacky when it idles for more than five minutes. The mode indicator lights on the t-case buttons will intermittently go off, and it will feel very boggy when accelerating. The connection to long idle times made me think might be a voltage issue.....I will check #32 for a possible blown fuse.

I installed the 10a fuse and monitor the charging system with the Tech 2, no change with or without that fuse.
