2012 Pro R P65 -PbS - Pb5 on Digital Display

[Bigcds68]

Dealer replaced engine and now the display has CEL and P Brake lights on and Pbs or Pb5 or P65 displayed. I purchased a used unit and it has the same issue. I don't want to buy another if there is another underlying problem. I read post from 2013 and 2014 on HCS 1 person replaced the display and it resolved the problem and 1 that it did not. I'm hoping someone has more information. The dealer says Polaris has never seen this before?

I would start by checking and cleaning all the wiring ground points to the frame. Weak grounds can make electronics do wonky shit.
The fact they never seen this before kinda leads in that direction.

I just got in the garage tonight. I’ll start checking all connections and verifying grounds. Thanks for taking time to reply. ill update my findings here.

Just realized there was a motor swap done that caused this. Would unplug every connector that they could've touched and look for pins being pushed back or damaged. Also look for crushed/pinched wires along the harnesses.

Well I've been through every connector and confirmed every ground. Tested every switch. No issues. It must be the display.

Found this over at SnoWest, doesn't sound good but does explain why both gauges are doing the same thing.

Does anyone know display code PbS or Pb5?

2012 RMK 800 with code on digital display. PbS or Pb5. Also check engine light and brake light are on. Sled is running fine. The Polaris dealer and I are assuming maybe a bad or broken brake sensor. Nothing in the manuals about this code. Does anyone have any definite answers?
