Hey Guys I need your help.
I have a Error PO315. The donor was a 2007 2.4 Manual transmission.
It needs to relearn I guess. But there is a problem. In order to relearn the parking brake has to be set. Well there is no parking brake and nither I or Lonnie did the wiring harness So I have no idea of how to bypass this....any idea? Anything I can do to jumper it in the Fuse box or on the BCM?
Help guys!

Thanks Jeff #312

I would be very surprised if it needs the parking brake set to do it. It might be part of a procedure, but I can’t see the ECU to learn the crank position.
That said, I can’t see your signature on my phone. I can try and see where the parking brake ties to in the 2010 service manual.

On an '06 LSJ the parking brake warning switch is #14 on the C1 BCM connector. It just gets grounded out to complete. But you don't have your donor info in your signature so I'm not sure this is useful information. Click the link in my signature to update yours to make sure you get the best help.
