don't hold the TCS button while starting a G37

[joe603]

Well it's not that big of a deal...but if you hold the TCS button to disable it, the car freaks out and has a few warning lights illuminated on the dash. The weird one was the parking brake light!?

Anyway, just something I noticed on my 09 G37 Sedan.

I had to turn the car off then start again to clear. Nothing damaged or anything...just weird!

[370Z/28]

You pushed it's buttons the wrong way.

I have some people that do that to me.

[timmy0257]

just curious, but was this an accident?

[audtatious]

So, holding the VDC button in causes "something" to happen? Wonder what that something is?

[joe603]

I was just in a hurry leaving somewhere and held it down quicker than I normally do. Didn't do it on purpose...

i dont mean to question you so much, but why would you have held it down while starting it to begin with?

eh, didn't even think about it. Just thought I'd share my findings.

[zozoka1212]

I am sure that disables it more than normally do. All cars have different stages. This could be one. Maybe I should try it and drive it that way. Oh yeah.

[timmy0257]

so u never actually drove it like that... i wonder what would happen.....

[zozoka1212]

I drive it with off all the time but not this way. I will test it out. Today is not a good day to play around. It is foggy. Couldn't see the front of the car the way home from work.

[timmy0257]

i only turn it off when i want to play. and after my episode i had when trying to do the video bypass, i think i will leave my car alone for a little while. haha.

[audtatious]

The only time mine is on is when I'm traveling on the highway or there is bad weather.....

[timmy0257]

is there a way to default it to be off?

[joe603]

yup:

scroll down to the Traction Control Memory Module.

[zozoka1212]

K I tried it and for me it works like normally do. No funky lights. Nothing. Maybe because it is an X and the ECU is different.

Joe has the Midas Touch

[Fezzik]

Its an x. Could it be an easter egg to turn off awd and be rear wheel. heh

[audtatious]

Until someone gets it to happen then who knows.

Joe, give it a whirl and report back

Hell, it's still under warranty if there is a problem

[zozoka1212]

It is easier than you think. The awd module is beside the ECU. You can take one of the wire of install a switch and you have yourself a RWD car when you need it. Mind you when you turn the swicth off you'll have an Xmas light on your dash. But when you turn it back on all is good.

[audtatious]

Has anyone figured out how to bypass the system so you can do brake stands (or actually heat up slicks at the strip for that matter) in an auto?

[joe603]

I just tried it again and it didn't do it...weird. I was parked on a pretty good incline when it did it.

[Mudgen]

^Check your brake fluid.

[joe603]

Better be good...car has less than 10k miles!

[Mudgen]

OK. Just mentioned because I saw a post elsewhere about crazy warning light behavior from bf being an ounce low.

[zozoka1212]

BF low comes usually with brake,VDC and slip lights. Also usually do it first when you accelerate hard or stop hard. This was I think due to the incline you were parking.

I bet the car thought the switch was not plugged in.

Within the first few seconds of starting the car it will run a myriad of self tests on switches, sensors, and circuits. If one of the sensors returns a an irrational (to the computer) reading it may freak out the system. If one system freaks out the others on the network are soon to follow.
The reason the BRAKE light came on was that is the warning light for the entirety of the antilock brake system. There was a fault stored for a VDC switch position error.

The normal driver would not the VDC off switch to be held while starting the car.

What does the 09 do differently with the VDC off?
The throttle cut logic usually kicks in quite quickly (thanks Toyota for making them do that....)

[timmy0257]

funny how joe says "dont" do this. then everyone tries it

[zozoka1212]

LOL tell your kids not to do anything and you can bet all your money on it they will try it.

install an old school line lock switch?
Then you don't need the brake pedal to burn out?

On the Ram if you pulled the ABS fuse it pretty much killed the traction control, that was how I heated my 325/45/18 M&H Racemasters before a run.
