VSC, Check Engine, Trac Off ?????????

I had a similar problem when installing my intake. I just reset the ECU and I was good to go, no problems since. Im pretty sure your supposed to unplug your battery before doing a CAI install.

My 3 stooges have been on for a while....even after reseting they come back on within a day...I am due for emissions testing...whoopie..... I did some research and found that if you rest the obd by removing the battery or pulling the fuse it will be an immediate fail as the computer will read not ready on some sensors as they haven't gotten the results back they require......my lights all came on back when I did the perrin CAI and exhaust on the car like in 05 ish.....looking like new o2 sensors are in call as the last time I was at the shop and had a test done it threw the code for a o2 sensor but we didnt knowwhich one at the time.....didnt bother looking it up as was no need to fix right away LOL......so just a lil heads up that reseting the computer doesnt always rest the system....I'll keep everything posted as to what was the exact issue....

Yes, its possible, but i'd recommend that you have injectors checked before going into replacing them. They should last a very long time.

hey i have a 2008 xb 5.0 and did not do anything to it and the past few weeks my VSC Trac ABS and brake lights have lit up. While they are on my abs and trac dont work. which is not good cuz of the snow. also my friend who as a 08 xb is having the same issues would love to hear if anybody else has this

get a OBDII reader and check what code is being thrown. that wil direct you to the main problem.

has anyone here with the light situation punched there dashboard repeatedly in a drunken all out rage b/c there new wife couldnt drive stick and u couldnt walk b/c of all the liquer in. well it happened for me and the next day after waking up with a hangover and flipping out the the new wife about leaving my e-brake on halfway there i had the same lights come on...there called dummy lights for a reason keep running your carthey will probably turn off at some point. if you notice a diffrence in your cars performance or see that your car is drinking oil or some other random shit the that is when you take it in to get checked and possibly get wallet raped!!!!

running with your E-brakes on would have heated the crap out of the rear drums which would kill the speed sensors. if ANY of the speed sensors die, it automatically triggers the vehicle stability fail safe and completely disables Vehicle Stability Control *VSC*, Traction Control, Brake Assist *BA, AKA your Brake fluid pressure booster*, Anti Lock Braking *ABS* and due to the disabling of the ABS, Electronic Brake Distribution *EB* is disabled aswell. we have 4 speed sensors, one for each wheel which sends the given speed to the VSC and Traction control systems for their monitoring and control. when one sensor goes out, the SKID-ECU no longer can accurately calculate the VSC and Traction Control, and because ABS, EB and BA all revolve on those systems *with just about any 2000 model or newer toyota vehicle* they ALL are disabled as a fail safe. those sensors aren't cheap either :/

dummy lights don't go out on their own. if they come on, there's a problem... the only reason why they are called "dummy lights" is because they don't give detail, they just say "hey, there's something wrong, check it". it's not a full on gauge telling you specific voltages, pulse ratings, resistances, timed activations and so on.

Hi all,

I just had the three stooges pop up. i stopped at the bottom of the driveway to get mail and when i got back in there they were.
I just cleaned my injen short ram. i have never got them before and it worried me.
I am going to disconnect my neg and see what happens.
let me know if you know of a fix for this yet.

Thanks,
Superman

i'll say it again...

pick up a OBDII reader.

here is a good one that i have that does the job: Harbor Freight Tools - Quality Tools at the Lowest Prices

really simple. plug it into your terminal port just under the dash on the left side.

put your key in, turn to "on" position and have the reader plugged in and it'll ready what you have for codes. right them down and look them up in the handy booklet that comes with the OBDII reader.

what ever code you get will have a direct relation to a specific sensor. get the general idea of what sensor it's working with *IE, exhaust, intake, valve timing, CAT, fuel line, speed, brake malfunction and so *. what ever it relates to, check the sensor first before you freak out.

it's that easy.

PCH · 01-03-2009, 06:54 PM

^^^ I got the same code reader from them when it was on sale for $20. Always works great and comes with codes definition database on CD.

superman_jjs · 01-03-2009, 07:25 PM

I took your advise and picked one up.
It gave me a too lean code.
I put some am/pm gas in her the other day and she is down to about a quarter of a tank.
could it be that with the cleaning of the filter and the cheap gas was the cause for my stooges?

Thanks,

PCH · 01-03-2009, 07:45 PM

That code may be caused by vac leak, bad first O2 sensor or may be bad/dirty MAF sensor. Some gas additives may affect the O2 sensor.
Try clearing the memory by disconnecting the battery or use the code reader and see if it comes back.

gravebox · 01-03-2009, 09:53 PM

another possibility is that your EVAP solenoid switch was activated to purge your fuel vapors and you may not have had any vapors to purge, giving a too lean of a burn. it's possible to happen.

other than that, i'd say the same as what PCH has going.

superman_jjs · 01-04-2009, 12:32 AM

Thanks,
i do appriciate the help.
I cleared the code and will watch to see if it comes back.
I have just under 40k on the odometer.
It may be that she needs to reset her self now that the airfilter is clean and she can breath better. I might have gone over the 25k cleaning by a few miles and with all of the bad snow here they have been putting down the sand pretty heavy.

Thanks again,

One other question,
where can i get a repair manual?
I check the store and they dont have any and the other store said that there is a 3 to 5 year wait after they come out before they make one.

Thanks,

gravebox · 01-04-2009, 02:52 AM

^^ PM me if you have an AIM, i will send you to full service manual. otherwise you'll have to pay 10+ bucks for an online download *which is what i did*.

I have a turbo Toyota BB with Greddy full Turbo kit. After I start my car and rev my check engine light comes on and then car wont rev over 3,000 rpms. Need help

superman_jjs · 01-11-2009, 01:08 PM

I got the code reader and my code was too lean. I cleared the code and it has not come back on. I am hoping that it was just bad gas or the vapor purge with no vapors.
Thanks for all of the help.

There is no way to know what the problem is until you check what your codes are with an OBD II scanner. It could be something very important, or it could be nothing. Since its triggering safety mode, I'd say its more of a serious problem.

My turbo kit is throwing 4 codes. MAF sensor says too much air, fuel senor says too much fuel, both exhaust sensors say too much airflow. But my car isn't in safety mode, I can rev all the way up to redline if I want.

what boost are you running? do you have upgraded injectors or running stock ones?

if you're boost is too high and the safety has kicked in, then you MAY have a serious problem known as engine knock which suggests you would be running stock rods which is BAD. anything over 7-8psi on the stock rods and you'll start going in to a very risky zone. some people are lucky and get away with 10-12psi, others pop their rods before they hit 9psi.

if you're running stock injectors and are running higher boost like 8-10psi, you may be running in to a brick wall with your injectors' duty cycles and could be getting too close to detonation which is another possibility.

are you running a piggy back ECU? has it been tuned properly?

there's loads that can cause that problem from turbo'd setups.
