I’ve replaced 3 of these on my rig so far and have determined a couple things.
1st one I replaced the rig had 12 miles on it. First ride out went into limp mode. I had to create a jumper to get it started again.
2nd one replaced was after I installed the parking brake. This was months after and thought maybe it was a bad unit.
3rd was the one that made me realize the parking brake was creating to much pressure for long periods of time. (Hauling on trailer). This would cause the brake fluid to eventually leak through the rubber seals inside and touch the brake sensor.
I’m going to be adding a kill switch to this setup so I can continue using the parking brake, and no longer worry about the brake sensor every time I’m in the back country.
FYI- a fuse can be used as a jumper in the field to get the rig started and keep you from being stranded. Having some wire or anything as a jumper will save the day- I’ve learned the hard way lol.
