Thank you very much for the help. The problem was infact the stop lamp relay. When I unplugged and opened it there was a lot of corrosion inside. Thankfully dealer had it in stock and was able to swap it out easily. Thanks again.
Hello all,
First post but thanks to this forum I've been able to fix my truck in the past.
I have a 2006 Hino 268 with air brakes which currently the brake lights stopped working.
The lights themselves are functional as well as the wiring going to them but they are not receiving 12 volts...
