[Binky7789]

Hi. I have a 05 1.8 petrol avensis. The asb trc and vsc lights came on the dash and appears to have knocked my brake lights out. So far checked bulbs and fuses and replaced brake light switch to no avail please help

Hi,

Try checking the output of the alternator / Battery voltage when engine running. Check DC voltage and also check for AC voltage as a failing diode pack leaks AC to electrical system. When this happens all sorts of lights come on.
