My BAS light comes on onlyu when it is hot outside like at +95F.
It generally does not come on when it is cold outside.
Someone told me that it may be the speed sensor?
what is the besyt way toi diagnose this problem?
please advise
Thanks
Barry

 

very common on this car that the brake light switch under the kick panel is bad. It's best to get someone to hook up with the laptop and pull code. if you replace any defective part, you will need the laptop to reset code....

good luck

 

I have replaced the brake light switch few months back. i have the code reader and there is no code showing per say. Someone told me it may one of the speed sensors on the wheel?
