First of all, welcome to RennTech  :welcome:

 

Pretty self explanatory, P1276 is an electrical fault involving the pump and control network for the PSM and ABS systems. Take a good look at the wiring around the PSM hydraulic unit, I think there is a TSB on moisture entering the harness connector at the PSM.

Thanks for the response. I will check :eek: on the connections. Could the module have gone bad ? any other ideas if there is no trace of moisture at the connector?

It could also be an electrical fault in the pump itself.

As said above, could be your battery. Mine was old and a couple weeks after purchasing my CTT, the dashboard would lite up like a Christmas tree. Replaced the battery and boom, it all went off.

Only problem is that while a failing battery or dying alternator will trigger the dash MIL's, the car noramlly would not code when that occurs, which the OP's vehicle has done.

Hello I have a 2010 cayenne and I have the same issue but I think I know what will be the main problem, a couple weeks I notice water on the carpet at the passenger side I thought that it was the condensation mustuire coming from the ac under the passenger side dash but after a exhausting search I found out that the problem comes from the ducts full of mudge exactly located it on top of the tire and under the abs pump I cleared it from leafs and all kind a dust literally 2 litters of water cane out problem fix! Finally but I’m suspecting because of that the electrical connections may become wet causing the 1276 code anyway I hope this help and probably this week I will dissemble the whale thing in other to check it if y fix it I’ll get back with more details good luck guys
