    That's how they're setup.

    Brake light switch ties into many things.

    Thats pretty bizarre for a brake switch to trigger an engine fault , how many people would pull over and then as the book would suggest contact a dealer for service , yes i do know the brake light switch would disable cruise control and stop brake lights from working but hey its todays technology so anything is possible I suppose . Thanks for clarifying that anyway .

    From memory a faulty brake light switch on a T4 shows as a glow plug light.
    Understand how it works, troubleshoot logically BEFORE replacing parts.

    See in the good old days other courteous drivers would tell you your brake lights were not working , so you would check the bulbs or check the fuse or the switch itself , if this is todays way of showing a fault how many would have replaced their glow plugs or EGR or one of a dozen other things before getting to a switch on the brakes . Don,t worry guys I am not long before shuffling of this mortal coil and you wont have to worry about me griping about car technolgy on the Forum -------------------------------------------But not for a long time yet only a young 65 so plenty of time to keep annoying the crap out of the purists , unless I kill my self Moto Cross riding . HA HA .

    ... and back then, if it was a Pommie Ford, there was only one fuse to worry about.

    When this appeared on the dash of my first T4, I thought it was a dud glowplug & actually phoned the dealer for a price. I can't remember now how I worked out what the real problem was, probably got the stored codes read.
