Probably a bit of a silly question, although I'm new to electrical diag. Troubleshooting an intermittent "Service Stabilitrak" with codes U2100, U2107, and U1096. The diag trees have me following U2107, then U2100, then U1096, it would appear. U2107 starts me with using the Tech2 to check if...

Ah, yep, I bet that’s the case. The official procedure assumes a brand new greenfield module; while one that’s already programmed may work. I can’t imagine the EBCM really needs to be VIN specific.

The service procedure for replacing EBCM calls for programming using SPS, unfortunately. Apparently this calls for both a Tech2 and a TIS terminal.

Based on the info in the procedure from post 27, use Dexron LS and do not add any friction modifier. It already has friction modifier in it. 88862624 Is the current part number. That is for the rear differential. Re:flushing, I may be a little risk averse but I’ve heard too many stories...

Anything current in the registry here?

Transmission fill procedure and then check procedure. Check to be done when trans temp is between 86-122 degrees F, check plug torque spec is 25Nm.

I’ll be doing this job soon myself. Transmission service. It calls for removing the transmission mount nuts: there are four, torque spec is 50Nm.

Diff fluid replacement…. And interestingly enough the service manual does call for 2.12 quarts (2 liters) of Dexron LS gear oil

Adding some context, as Mickey observed there are some part number supercessions, for historical reference and searchability. Manual in car calls for 75w90 12378261 meeting GM spec 9986115; and 4oz limited slip additive 1052358. In attached chart, they show 89021677 and same limited slip...

Got you fam. Gimme a day or two on the procedures, I’ll note that I’d personally avoid flushing the trans for me it’s just a pan drop fluid and filter change. The info about fluids we do have here: Post in thread 'Compression test procedure' Compression test procedure

The later coil connector; with the locator tab. Posting these just so there’s a visual reference.

The 06 coil connector

I recognize this is an extension of the conversation that started on the other thread. Disclaimer - I personally have not serviced an XLR ignition system so part of what I’ll say is only my experience in other coil on plug engines. I have seen the boots be the point of failure, usually if they...

Charge air cooling system is a little bit more involved, it has you using the tech2 to cycle the electric pump.

Cooling system pretty straightforward. The steps cut off from second photo are just “let engine cool, top off coolant if necessary, inspect for leaks.”

Great questions. PS system info attached. I’ll get the cooling system info next, and follow Mickey’s advice for the coils/boots.

So here are the relevant tidbits, for calipers, pads & rotors. Fronts: nothing fancy, regular dual piston calipers. Mounting bracket to hub is 175Nm. Clean the mating surface of the hub where it meets the rotor, while you have it off. Caliper guide pin bolts are 31Nm and the banjo bolt is...

This one I do have in PDF form - owners manual does a good job with this. Page 6-92 for capacities and 7-11 for specifications (including part numbers). The oil spec was superseded by Dexos1 Gen3.

Haha I know that feeling! I’ll look them up. It’s tricky as I can’t get pdf’s, just old school screen shots as you see. Do you have a tech2 you’ll be using for ABS bleed? Edit - and do you have a pressure bleeder of some sort?

And the diag table for c0035, with the values you can check with your multimeter. Step 9 is cut off but it’s “replace EBCM” and step 10 is just “clear codes and test drive.”
