What does it mean if the 'service engine soon' light intermittently comes on accompanied by rough shifting on a 1994 GMC Suburban K1500?
Sometimes when the "Service Engine Soon" light comes on, depending on the problem the computer will go into "Limp Mode" which are factory settings for different sensors. This also changes your shift settings. Limp Mode will allow the vehicle to continue on its way but will run bad enough to make you get it fixed. The trouble codes should be stored. When retrieved may lead you to the main problem. When problem is fixed clear all trouble codes. ______________________________________________________ Update 7/7/08: I'd also suggest getting your transmission looked at. Sometimes when the "Service Engine Soon" light comes on and you feel a difference in how the transmission is shifting it can mean that the computer is detecting slippage in the tranny. It will then crank up oil pressure in response to this. In doing so, the engine can sometimes shift "hard" (thats how my wife described it) which can cause problems in your transmission such as breaking the shell around the gears. If you do get it checked & cleared make sure you right down the codes in case you go you have to get work done later. An experienced mechanic will know if what he is fixing is the problem or the symptom based on error codes. If you don't you could end up fixing the same thing twice.
2001 L200 security light comes on intermittently when driving When the car is stopped and restarted the security light turns off It is not flashing What is causing this to happen?
Answer Try going to the dealership's service department. Most will have what you need on their computers and can print a copy for you. They did it for me in Houston, for the AC system. You have to ask nicely, as always, there are some people who try to take advantage of the service. This will anger the service guys and then they will not do it for anybody anymore.
The American's with Disabilities Act does not apply to service dogs in training. Some states have laws which permit trainers to take service-dogs-in-training to the same places fully trained service dogs can go. However, most states require service-dogs-in-training to be accompanied by a trainer from a recognized program for training service dogs and that they carry credentials which they show on request.
A GMC Suburban requires routine scheduled oil changes and inspections every 7,500 miles or 12,000 kilometers. Every 45,000 miles additional service is required such as changing the automatic transmission fluid, and transfer case fluid. At 150,000 miles a flush of the engine cooling system is recommended along with a thorough belt inspection.
I had this on my 2005 S40 diesel. I contacted Volvo and they told me there is a small tank next to the fuel tank which contains 'eolys' which is a liquid that is intermittently injected into the system with the fuel and it cleans the 'DPF' (diesel particulate filter). This warning comes on when the 'eolys
