OK what is the BPMV Pump motor, and why would it stall? I got a c1243 message today, and my abs, traction control lights came on. I cleared the code and restarted the car.. Everything else seemed OK

 

Jared - The BPMV is the Brake Pressure Modulator Valve and is the heart of the anti-lock brake system. The pump motor functions to maintain the appropriate hydraulic pressure in the system for braking, traction control and stability control functions. C1243 is set when the system self tests and insufficient pressure is detected when the pump is turned on momentarily. I am not sure why you would get a transient code. You might want to check the brake fluid and consider bleeding the system. Hopefully it is not the pump as it is not separately serviceable. You probably don't want to hear that the BPMV GM list price is $1750. :eek: Good luck.
