Anyone have the Charging schematics for a 2006 Cadillac Escalade 6.0L ?

It seems the F & L terminal on the alternator DO NOT go to the PCM. C2-15 and C2-75 are NOT populated on the PCM connectors. Instead, the L & F pins go to a connector about 6 inches from the PCM connectors. Whats this go to????

Here's picture of connector...

To the BCM i believe, probably to show charging system status and voltage, to the gauges.

Looks like the plug goes to the generator battery control module. I have the diagram but I can't seem to figure out how to make it small enough to post on here. Anyway if there are 8 wires in that plug, looks like they should be something like this, A-red/w-battery, B-gry-battery field duty cycle control, C-red/w-battery, D-brn-charge indicator control, F-blk/w-ground, H-blk/w-ground, J-ppl-generator regulator control, K-org/blk-class 2 serial data.

One more thing, c2 15 (ppl) goes to the generator regulator control (J) of GBCM and c2 75 goes to generator field duty cycle control (B) of GBCM and also to alternator (2). I KNOW this would be easier if you could see the diagram for yourself!!! If someone could tell me how to make it small enough to post on here I'd try it again!

Thanks much for the information...I found a buddy today that has a 05 truck and looked at it..

I wonder if I hook the brown wire back into the PCM if it will turn on the alternator?

I don't know about that, not sure what all is in the GBCM. Is the alternator not charging at all? The 2c 75 gray wire isn't turning it on? Not sure how it exactly works, just wondering.

Ok, that looks like the schematic you need, where did you get it and what's it for? The one I have has a purple wire from GBCM (J on plug) to PCM (C2 15), and the gray wire (B on plug, GBCM) to C2 75 on PCM and also to alternator. Sounds like the schematic is for what you have since you stated that there were no wires in C2 15 & 75. I checked Chevrolet diagram and it looks the same with the exception of the GBCM has 9 wires not 8, (dk blu G on GBCM plug-for supplemental brake assist pump motor). Anyway I hope you get it figured out!

I entered VIN of the 06 escalade into gm service information (friend who works at a dealership looked it up for me). The connector I have has the blue wire in G, goes to C100 pin E. Service information did not show this wire at all....I don't think I'll need it.

I guess the GBCM is only on the 1500 models, go to 2500 trucks and the alternator goes to the PCM

Cool, glad you got it figured out!

Blue wire is Engine on signal. Did you delete your module, or did you use it? I just ordered one on ebay with a negative cable.

did not use the module, alternator worked fine letting the PCM control it, as was done in past years.

Where (which pins on pcm) did you run the gray and brown(alt) wires?

Did anyone use the module? I can't figure out where the og/blk serial data cls2 wire is supposed to go? I assume I can get rid of the blue 'engine on' signal wire. Anyone?
