2014 STS Parking brake and left control switch not working - advice?

[RUKNOT]

Hi guys, I have a 2014 Can-Am Spyder ST -S that I've got a problem with. The left housing switch doesn't work some of the time, and the parking brake stopped working completely. I've tested the switch and is shows the correct resistance, the wiring to the switch gives 12v. The Parking brake motor works fine, took it off and connected it directly to the battery to test. The 2 wires to the PBM Don't give 12 v power. I feel like the 2 of these problems are correlated but cant figure out the wiring diagram on my own.
Maybe someone has some advice?
Thanks in advance! :banghead: :banghead: :banghead:

When the left hand multi function on my 2018 RT statred acting up I had to have the whole thing replaced. Now waiting for the parking brake motor replacement to arrive.

STS Parking Brake Issue

From the wiring diagram in appears the Parking Brake Module, located at coordinates K&2, could be the issues.
Its directly between the switch and motor that you state are working components.
Check the continuity of the PBM wires to the Motor + to 11 and - to 4 and the Switch 10 to 2 and 11 to 3 and 12 to 1.
If all good then I would replace the Parking Brake module.

:dontknow: The 14 got p-brake switch on L controls? 13 was down on dash with heated grip & fogs. Lil easier to access & all either way check battery connections too:thumbup:

No, the P switch is in the center console. They just both died at the same time

The problem is that I cant find the PBM, on the RT Model it is located with the windshield motor. On the ST model it is a separate module which I cant find. My suspicion since it died with the left control, is that it could be an ECM problem

Stripped the bike, the left control switch randomly decided to start working again, the p brake is still dead
