I trying to get the 04 xlr back on the road. So i purchase the susp.module and TCM module took it to cadillac and told me the pump is bad so they cant finish the convertible part....they want 1900$ for the pump +labor n i have to buy it from them if not they wont install it. 
So since they told me they only installed the suspension module ,i belive it will fix the ABS and the T/C light but i DIDNT, and the car still drives very rough on d ground like no shocks (i have 20"wheels on it ) after 30mph it feels the engine forcing itself to go higher ,however the "do not exeed 80mph still on dash"
so i talk to the mechanic and he mention the EBCM it could be bad ..he's not sure.. and that takes away the abs and the t/c
What is the EBCM its it a part i can replace myself ..???
Is it driving rough becauseof that???
Can i purchase the convertible pump and change it myself???
This website is my last hope since dealer dont seem to help that much, by just making me buy parts from them only
Thank u
