ok i read on a page dont remeber where. but it caught my eye. it said that some one holds there DSC button for about 5 sec. when they start there car? what does this do. i did it and the traction control light came on.. it wont turn off till u turn your car back off... whats this doing?

 

Please do a search.

Close this thread.

 

It's also in your owners manual. 1 push disables DSC, 7-9 seconds ish disables the traction control intervention. 10-8000 seconds (133 minutes.. ish for those of you that calculated it like i did), you might want to look at your gas gauge... :D

 

Thats your answer. The only thing I can add is that when you do the 7 sec. hold to disable the DSC, it will put an error code into memory in the ecu. It won't throw a CEL. This code will be reset by the dealer next time you go in for service. Or if you have a ODB II scanner, you can clear it your self.

 

not true - see other thread for the squashing of this myth

Same difference to alnielsen's correction. That other thread has some innacuracys, I'm gunna chime in on that other thread.

But in short alnielsen is correct, and the exclusion of page 5-25 can make the conversation mis-leading. It is possible to disable the DSC, then the TCS. Not vica-versa, when you think about it, and the events that occur the other way around it makes sense that it's not allowed.

So yeah, the 7+ second hold trips an error. I wasn't aware it logged in the obd system. I'll have to pull out my scantool.



Below Taken from Page 5-26 in the Owners Manual: although other linked thread has a pretty scan

l If the DSC OFF switch is pressed
and held for a second or more, the
TCS/DSC system may become
inoperative due to the system
detecting switch trouble. If the TCS/
DSC system becomes inoperative,
the TCS/DSC and the DSC OFF
indicator lights illuminate
simultaneously. In this case, turn off
the engine and restart it to restore the
TCS/DSC.

 

No pretty scan for you this time

On page 5-23, "Note: To turn off the TCS, press the DSC OFF switch".

 

A simple press of the switch won't throw a code. It's only when you do the 7 sec hold that a code will be thrown.
