Bistable Relay (BR22)

Good morning guys. I have a 2010 Cascadia, woke up this morning and my batteries would not turn the engine - good attempt, but not enough juice.

Luckily had a friendly driver next to me and he helped me jump start the truck. I had cables and put them on but still unable had to put his cables on to start it (2 sets of cables).

I got an error code: 33 SPN 520415 33. I researched the code and found that Bistable Relay (BR22) implausible output state.

I can't find this relay - can someone direct me to its location? I would hate to pay $50 - 100 to the dealer if it is an easy plug and play relay that I can do myself.

And would this relay cause the batteries to drain or should I have them checked (maybe gone bad),

thanks again for all your help.

 

Thanks Mark, wish I would have seen your diagram before going to FL to get screwed. Asked the "Technical" person at the counter and he sold me R10, not BR22.... Well at least I have a spare, but am going back tomorrow on my way to S. Dakota to get the one I need.

Any words of wisdom on, does / can this relay cause your batteries to drain? I am going to have the batteries tested in about 20 minutes to find out if I have a bad battery/s.

thanks again,
