Guess I just assumed that code was the dead bulbs in my cluster and the HVAC controls. I’ve pulled the combs out of both SP205 and 207 and found the modules or at least the harness going to them showing ground. I removed the digital radio receiver last night. That was the old XM module, this was...

I currently use Car Scanner ELM OBD2 for my IPhone. Up until today I had not been using it correctly. I finally found out how to really scan the truck and now it is showing codes that I was only previously getting from the terminal. Thank you guys for the help I'm going to continue to follow...

Just watched your video. Glad I did because I was thinking I’m still looking for a fault that doesn’t exist. But the ground showing up in the bus I know is an issue. Wish I had a way to watch my data bus like that. I would try to put together a built in scanner for the truck using my raspberry...

Negative. I drive it daily. It actually runs great. Good power and shifts as it should. It just tells me to service stability and brake system every day. And then the red brake light will come and go as I’m driving. Abs light stay on steady. Also it’s the awd version. So it won’t go into 4-lo...

This is the connector inside the bottom on the front doors?

I believe this to be true now after some research. I was doing some reading about the data line in the truck. This is supposed to be 5-7 volts at PIN 2 on DLC. I’m getting between .29-.79 volts. This is unaffected by DDM as nothing changes when it’s unplugged. Should I one by one unplug the...

I have an apple phone. Have yet to find a terminal app that will pair with my Bluetooth device. I will update as soon as I figure that out. This evening I should have time to try some more probing with the multimeter. Need to find out which module is grounding out my data bus.

I cannot currently. Using an app on my phone with terminal without an option to log what’s input output of terminal. If I could find the correct program on my laptop I could do it that way.

I’m not finding any info on Google about how to test it. But I can say all functions work without issue.

I’m thinking the same. But would like to test it first. I thought that’s where I was getting ground in the data bus. But turns out I potentially have multiple other modules shorting to ground

Just bought this 2004 Tahoe AWD LT. Has all options excluding auto leveling suspension (premium smooth ride instead). Not a lot of these things work anymore. The truck needed all brake lines when I got it. Installed Dorman brake line kit for stabilitrack vehicles. New calipers all around...

I don't want to hijack or revive an old thread. But I'm having an issue with reading codes with this exact setup I can not get the terminal to spit out anything. It just says "CAN ERROR" @TJBaker57 can you pm me as you seem to be very knowledgeable in this subject.
