exercising ebcm on 99 C5
I know this has been covered at length but I'm trying to cycle my 1999 coupes ebcm today and can't remember which wire to apply a 12 volt power source to. Every couple of years when I take the car out of storage I need to get the control module working again. Once I cycle it the dreaded codes do not return for at least the season. I know I could go and get a tech 2 to do this but would rather just do it in my garage myself. I've been searching all afternoon and cannot locate the specific directions to do this. I drove the car last night for the first time this year and holy crap on heavy acceleration the stabilitrac failed and I almost lost control. lol. Was not expecting that. Of course now abs/traction/stabil are all inop.
Thanks

I didn’t want to short anything out so I used another method. It worked great for my 2000 Coupe. Raise the rear wheels off the ground. Place jack stands under the control arms so the axle shafts won’t be at a bad angle. Start the engine and put it in second or drive and only let it idle in gear turning the rear wheels. Do this go 5 to 10 seconds then let it cool after a coil please of time. Do it a second time if necessary. This makes the ebcm pump work as front wheels are stationary. I blew the 30 amp under the hood as my pump was really stuck. Clear code (probably in history now)

Thanks. That worked great and is easier to do.

I would like to know which wires are needed to splice into here. I'm having issues with the ah/tc/abs and it gives the error as soon as the engine is started. Once the error happens on the dic, the abs pump is off, and even lifting the rear wheels will not set off the abs pump.
