another question on ABS/TracCtrl issues
hey guys - need some advice
I've got 2 separate dealerships giving me some conflicting info on the usual ABS/Traction Control lights - the car threw the C1243 code (stalled ABS pump motor) - one place says I need an ABS pump motor (the BPMV) and this will solve the problem - another GM dealership is saying I need the EBCM since that is the unit that actually controls the abs pump, and that will solve my issues. The grounds all check ok, etc. I can get the stuff cheaper than the dealerships are quoting me, but it's all special order stuff and isn't returnable in the odd chance I don't need it - in anyone's opinion, where would you start?

- agreed -- one is saying that - following the flow chart (on GM service doc. #565848) - that the resistance indicates the ebcm should be replaced and the other is saying he's seen these tests give inaccurate results before - yeesh
anyone with this problem ever have to replace BOTH the BPMV and the EBMC??

i just had my 02 fixed today.i scanned with my predator programmer and got a p1571 code (traction control pwm link problem) .the dealership scanned for dtc .got a c1214, solenoid valve relay coil or contact circuit open.tried to clear it and resets right away.they checked for service bulletins and were referred to document #670663 for diagnostics and schematics.suspected shorted ebcm as per diagnostics.they replaced the ebcm. abs,traction control and tc switch work properly again.no codes and no tc or abs lightup on dash.$1960 for ebcm 
and $185. for labour.this is canadian dollars ,so it could cost approx. 20% less in U.S. its a good thing i had the extended warranty.the module part # 12216561
