Well ,that's because there is a problem with the system an there are What are call DTC'S -diagnostic trouble codes stored in the modules , computers ! You need to take to a repair facility that has a professional grade scan tool that can read codes in the body control module !
SERVICE VEHICLE SOON
The IPC illuminates the SERVICE VEHICLE SOON in the following conditions:
?€¢
The BCM detects certain malfunctions in the lighting system. The IPC receives a class 2 message requesting illumination from the BCM.


?€¢
The IPC detects a loss of class 2 communication with the BCM.


This year vehicle as with all newer vehicles have several control modules that control the engine , air bags , antilock brakes , anti-theft system ,Heating an air conditioning ,the instrument cluster an some others ! These modules are all connected on a class 2 serial data communication network so the modules can share information ! Your best bet is to take it to GM dealership or a ASE certified repair shop before you guess an just replace parts , that will cost you more in the long run !

Control off traction the trac off button lights up that wont let me turn it on what might be the problem


The light comes on and goes off when you start the engine as a test. If the light comes back on, there is a problem and you need to get the body computer scanned for trouble codes. The traction control uses the engine and ABS braking system to work.

VSC off VSC trac on as well as check engine light on but the car is working fine I've driven with both the lights on? Is there something wrong, what should I do? Should I stop driving and how can


VSC is vehicle stability/skid control. Find the button that turns it off and on. Push the button to turn it on and the light should go off. Most cases systems like these will have a light stay on any time they are turned off. If the vehicle is a 96' or newer call around to your local auto parts stores and you should find one that will scan your vehicle for free and tell you why the check engine light is on. If the two problems are related the scan should tell you what part of the VSC is malfunctioning.

Check engine light and vsc trac off lights stay on. Cannot turn svc off by pressing button on Dash


Hi, have you scanned the vehicle to see why your check engine light is on? IF no, you need to. Toyota/Lexus computer system illumniates both engine light and VSC lights whenver a fault occurs in either unit. VSC or stability control is like trac-control or ABS braking system. Get car scanned and make sure all computers are scanned for additional codes, repair them first reset lights and test drive. ON a side note, fixing check engine light will usually take VSC light away also, however sometimes the VSC system will glitch out and a Steering Angle relearn is necessary, it takes about 3mins to perform and a good quality scan tool with 2004 current software. Good Luck.

Why when i start my car some time it dosnt start up straight away all the lights on panel is on but the engine wont start up


Lights on the dashboard will show up when the ignition is turned on (when your key is half-way turned). They dont need the engine to be running for them to work.

If your engine wont start, it can be numerous things. It is best to let a mechanic to look at it.

My service engine light and trac off light are on


It sounds like you need to replace your computor. You could try resetting the computer first. The car maybe in lockout mode. Try turning your car over….leave the ignition on. Wait exactly 10 min. Then try turning over again….again leave the key on. Wait exactly 10 min and do it a third time….this time the car should start…maybe run a lil rough while it relearns the processes of your vehicle again. It is important to wait the exact 10 min each time. You will probably need a battery charger or a set of jumper cables because if your car goes low during this process it will not work. Good luck and I hope this works.
