I successfully repaired my EBCM today by soldering my relay!

I removed 5 of the 6 T20 screw from under the vette. it's more easy from under for sure! but how? I digged a little vette pit for changing my oil and do some other vette repair including this EBCM stuff!!

So if you have space where you can dig do that it will be more easy! I digged a hole of about 2 feet by 8feets by 1.5 foot...

Thank you!

I will take some photo of the pit tomorrow

2003 C5Z

The only code I'm getting regarding the ABS/TCS/AH issue is C1242. The issue is intermittent and if I drive the car around for awhile it starts working again till I park the car and let it sit overnight. I sanded all the ground bolts in the engine bay as well as the ground rings on the ground wires so there should be no grounding issues. What are some other 'free' repairs that I could do before having to pull the EBCM and inspect the unit itself? Since it's intermittent I am hoping it's fixable because I have no money to be spending on anymore repairs right now. Any info that anyone could give me will really help me out. The issue is getting worse and worse and I'm afraid it will stop working altogether soon.

C1242 c h BPMV Pump Motor Ground Circuit Open

The issue deals with the small connector under the main EBTCM connector and the circuits that run the main BPMV Motor.

The very first thing that I would do would be to make sure that connector and the wiring is in good condition.

Next would be the internal EBTCM circuit/relay. DELPHI did a crappy job soldering the connections on the main board inside that module. Maybe all it needs is a solder joint repair. The relay that runs the motor could also be going bad. Its replaceable if you can solder and are handy.

Start with the easy stuff first.

Here is the schematic that deals with the EBTCM and that motor.

The ground that deals with the motor is G-103.
