    2007 Yukon Denali - Brake - Traction Control warning lamps

    This was simply low brake fluid. That's all. I checked all the brakes and the were all very worn. So that's where all the fluid went. I wish there was a message that says - low brake fluid - but there isn't. This is the warning you get when the fluid is low. I just replaced the pads and rotors...

    2007 Yukon Denali - Brake - Traction Control warning lamps

    Yeah, so many sensors, I see there is a speed sensor in the transmission. There are also L+R transfer case output shaft speed sensors. The 07 Denali has so many electronic systems. I have not had to dig into any of that stuff. So far, so good.

    2007 Yukon Denali - Brake - Traction Control warning lamps

    Thanks for all the comments. I'll keep an eye on things. If this was just low brake fluid it's a bit odd they don't have a "low brake fluid" message. That would have been far more helpful than a brake warning lamp and message saying "service brake system" and a TCS off warning lamp. The...

    2007 Yukon Denali - Brake - Traction Control warning lamps

    Well this is embarrassing. I checked the codes today. There was a code for low brake fluid level. I checked the level again and sure enough it was a tiny bit low. Not sure what I was looking at last time. I added some brake fluid and checked the wiring and connector for that sensor. Sure enough...

    2007 Yukon Denali - Brake - Traction Control warning lamps

    Yeah, I fully expected a faulty wheel speed sensor. That would have been a straight forward fix. But it appears they are good. I did check the history but the only code in history was for low brake fluid. Fluid level is ok. I ignored that record. I will check everything again today but I think...

    2007 Yukon Denali - Brake - Traction Control warning lamps

    Ok will do. I did scan the chassis module - no codes with the truck not running as you probably suspected. I'll try again tomorrow and make sure the warning lamps are on this time.

    2007 Yukon Denali - Brake - Traction Control warning lamps

    Thanks, I did a scan using the GM Tech2 scan tool. Sadly no check engine lamp, no diagnostic trouble codes. No blown fuses. No ABS lamp. No symptoms when driving. Brakes feel fine. Just the Traction Control Off warning lamp and the brake warning lamp and it chimes likes 20 times and that...

    2007 Yukon Denali - Brake - Traction Control warning lamps

    Hi, I have a 2007 Yukon Denali. I have the dreaded Traction Control Off warning lamp and the brake warning lamp. For some reason, no ABS warning lamp. Just Traction Control and Brake. These lamps come on right away after starting the truck. Sometimes before the truck even moves. Any help would...

    Brake Light Switch Broke – Stuck in Park - not cool at all

    I don’t like the design of the park interlock switch on my 2007 Yukon Denali. This weekend I parked my truck in the driveway. I had planned to leave in like 5 minutes. Instead, I come out, start the truck and it’s stuck in park. So ... the thing sat in the driveway blocking everything for a...

    2007 Yukon Denali – Driver’s side rear door – full of water

    OK I noticed that my driver’s side rear door was full of water today – like at least a quart. It rained last night and all morning. This truck is new to me (it has a few issues). This has obviously been doing this for a while. There is a hole in the inside door area about 5 inches up from...

    07 Yukon Denali - Backup Camera Install – Aftermarket Head Unit – AUTO-VOX Cam1

    You may notice I have the bracket pulled up pretty high. It's because I live in NJ. If your backup cam hangs over the plate and obscures the words New Jersey - you will be pulled over within about 20 seconds. The cops hate it when the plate is obstructed. They are usually nice about it, but...

    07 Yukon Denali - Backup Camera Install – Aftermarket Head Unit – AUTO-VOX Cam1

    Oh it's painful for sure. Those YouTube videos are a real life saver. At least you can see where all the clips are and the order you follow to get the plastic panels removed.

    07 Yukon Denali - Backup Camera Install – Aftermarket Head Unit – AUTO-VOX Cam1

    I just thought I would post a note on installing a backup cam on my 07 Yukon Denali. I have not seem a single video that shows how to do this. But there are three YouTube videos that have just enough information to make the job straight forward. The links are below. My truck came with an...

    2007 – Yukon Denali AWD – Drivetrain Clunk (slip yolk?)

    Thanks, I'll check it out. It will take me a while. I'm getting my Envoy ready to sell. Just polished the whole thing (it's black - and now it's very shiny). That was a ton of work (too much really) but people buy cars that are pretty. Once I get that thing off to it's new owner I'll have...

    2007 – Yukon Denali AWD – Rear Seat Entertainment + Aftermarket Radio – no fader

    Oops - wrong section. Thanks so much fore the replies. I was a bit confused but that explanation makes perfect sense. It has the Bose system. I just checked and the rear speakers (the ones in the rear doors) are indeed playing with the fader set to the middle. So it's a digital fade and you...

    2007 – Yukon Denali AWD – Drivetrain Clunk (slip yolk?)

    Thanks for the replies. I'll check it out. I can certainly live with the clunk if that's just what the driveline does. I do indeed have a Tech2. It does come in handy. I have a 99 Suburban and a 2006 Envoy Denali. They are both getting sold and the Yukon is the replacement.

    2007 – Yukon Denali AWD – Rear Seat Entertainment + Aftermarket Radio – no fader

    I have a few questions about my new/used truck. So … I just bought a used 2007 Yukon Denali AWD. It has an aftermarket radio – Pioneer AVIC-X940BT – Navigation Radio. The radio works. The prior owner had it installed at a shop. I’m hoping they did the job properly. I have not looked at how...

    2007 – Yukon Denali AWD – Drivetrain Clunk (slip yolk?)

    I just bought a used 2007 Yukon Denali AWD. It has 140K miles. The truck was pretty well maintained. It’s had a lot of service done over the years. Most of the suspension was serviced – all new shocks/struts, air bags, compressor. The left motor mount was done at 120K. In general, the...
