02 suburban DLC wiring schematic
I have a 2002 suburban and the dash is freaking out and i can't connect a scanner to the computer through the OBD 2 port. I'm getting all these touble codes: P1626, U1026, U1041, U1064, U1300. My ABS light is on, My Air Bag light is on, My temp gage and gas gage don't work. And my message center is scrolling between a battery symbol, "security", and Low Fuel message. I spent a lot of time looking for shorts and worn wires, but not knowing where to look makes it difficult. I read in another forum that somebody had the same problem and they used the splice pack under the dash and the DLC wiring schematic to determine where the short is and what wire to trace for problems. I have a Haynes manual but it does not have the DLC schematic in it. Does anybody have a copy of this diagram they could post for me. Specifically my vehicle is a 2002 Suburban LS with a 5.3L flex fuel engine.

my dash was doing funky things, gauges dropping out truck shutting off etc. I would suggest checking your grounds, I ended up running a new one behind the dash and it solved all that ailed it. still get the abs and brake warning lights, but thats because of the wheel speed sensors...

sorry about that, I didn't realize i missed that until i saw the heading on the pdf you posted. I have one more thing i am hoping that i can get my hands on. I found a schematic that shows how all the different components are connected, but it is for an older model. I'm hoping i could find the same schematic but for my year suburban. I have attached the schematic i have found for a reference. If you have one like this for mine can you please post it for me. Thanks
