Hi Guys,
A mentioned in subject I have the VSA, Brake and ABS light on all the time.
Pressing the VSA switch makes no difference.
I disconnected the battery and reconnecting. Still on
I looked at the brake fluid level and it is OK, I pulled the plug of the side of the reservoir and put back. it made no difference. I only have simple OBD11 tester. Where should I start? Does it need to go to a shop for a code check?

I pumped up the tires to the correct pressure and started to take the car to the local shop. The lights went out. So not sure what is going on.

My 2004 did this a number of months back. Did what you said besides tires. Took to my buddy who has a HDS scanner. He saw a low voltage (battery was like 3 months old). Cleared code, I drove away from his home with them off, and then they came back within like 3 miles.

I found a thread on here about recalibrating the VSA system, so we did that. They haven’t come back yet. 🤞🏽

 

Thank you for the pointer. I just searched YouTube on "recalibrating the VSA system" if it comes back, I'll reset it. In my case I have a 2005 TL. As mentioned brake fluid was OK, tire pressure was slightly low, but it's been lower in the passed with no issue. This car does not have the TPMS fitted. What could have triggered it?

It could be a wheel speed sensor sending bad data to the car. You can use your OBD2 scanner and see why the DTC is on.

 

I bought a cheap scanner, could you recommend a good one that can catch all codes?
I'd also like to get a scanner which can read transmission codes. We ran into an issue. Are these two separate readers?
