Stability system disabled light on no power


The stability system is software programmed into the ABS - antilock brake control module also the PCM - engine computer . service engine light DTC'S - diagnostic trouble codes stored . Your best bet , take it to a qualified repair shop or the dealer . You don't have the diagnostic equipment or knowledge to tackle this type of problem .

Gmc yukon denali reduced engine power stability system disabled


I had the same problem in my Yukon Denali And after 4 throttle body's, replacing gas pedal, rewiring the grounds replacing sensors, took it to not one but two GMC dealerships who were useless they can't fix their own trucks they're not the brightest !!!! After thousands of dollars I found a mechanic very familiar with this issue you want the solution it will cost ya 500$ for me to tell ya!! Just kidding I know how frustrating this problem is okay here is the fix the problem is these electric throttle bodies are GARBAGE!!!!!!! Don't matter what u do or what u replace it will come back on unless u convert your electric throttle body to the old cable throttle the actual fix was 900$ but I spent thousands and thousands trying to fix it!!! Please save your money and tell ur mechanic u want to convert to the old cable throttle!!! Gmc is well aware of the problem but won't fix it for u cuz they're useless

My service stability message is coming on on my 03 Denali XL. Any idea what the problem could be?


there could be any sort of problem, you will need to have it scanned for codes, these codes will tell you where the problem is, (a sensor or pump etc.), then you can diagnose the problem from there, will need a scan tool to get codes,

STABILITY SERVICE MESSAGE


This is the same as a check engine light or an ABS light. All three systems have their own computer and the ability to store error codes. Once in a while all you have to do is hit a bump and a code is stored. I'v been driving my 2004 Denali with this situation for over two years. If you don't feel ANY changes in the steering, braking, or the general conditions of driving than you've got nothing to worry about. If you DO feel a change in any of the above, then have the vehicle serviced asap. Thanks, Dana

Stability control engaged and my traction contol comes on at intersections for 4-6 seconds , the power drops, causes a panic in the intersection. Dealership says their are no codes in the denali to support...


vibration would have loosened the solder joint on one of the main two leads into the ABS pump on the ABS module.checkout and replace the defective solder, the stability control will work again.
