Leave your battery unplugged for 20 mins. Just disconnect the negative terminal. Then plug it back in after 20 mins. The ECU should loose all the settings.

I just cleaned my Mass Air Flow Sensor and Throttle Body today. I was reading the DIY on cleaning the TB and they said don't unplug the TB connector. But someone said that if you unplug it you can do the re-learn steps for the ECU, or you can leave the battery unplugged for 20 minutes.

I had to unplug it because the TB cleaner said not to get it on plastic or paint. I didn't want to risk it. So before I disconnected the TB, I unplugged the battery. It took be about 30 minutes to clean the TB. I put everything back, and hooked up the battery last. I turned it on and no problems.

 

I would unplug your battery or do the ECU reset procedure...

 

Can you explain me how to make the re-learn steps?
Thanks!

I have the same problem! My vdc off light is always on!switch doesn't do anything!I'm wondering if the previous owner did a mod on it??

 

i had the vdc off/slip lights on for a while. changed my brake pads and it was fine. also got my mechanic to clean my throttle body. no lights have come on for the past 2 weeks after the brake change

 

when u disconnect the battery and the vdc/abs/slip light(s) come on you have to recalibrate the steering angle sensor, and sometimes the decel G sensor. Only way to do it properly is w/ consult 2 or 3 at the dealer.

 

My VDC off light came on and its not going away! I shut the car off drove it for 30 miles and everything but even when I restart the car the light is still there what do I do? The button does not do anything.

 

either brakes or throttle body

 

I recently cleaned the throttle body the car starts perfect and my brakes are good i have checked them
