hi im alex happy to assist you, i would check your clutch switch on the pedal

Ask Your Own Medium and Heavy Trucks Question

this is the most common issue when cruise and engine brake do not work on this model

There are two wires going to the switch which is like a toggle lever on the clutch pedal, both wires when tested with a test light show no current

it is ground controlled, sends a ground signal to the ecm, should go open and close when you toggle it

I put the cruise switch to the on position, with key on truck not running, no current at all, should I have to select the other switch to which makes the cruise set it's speed/rpm then check at the switch on the pedal?? Also I checked on the rear of both switches with the key and or headlight switches on I show current going into the on/off switch and the resume switch but no current going out when I toggle it

wire 97-GC is the input to the switch and 97AE is the output to the ecm both violet wires, and the dark blue wire is the feed for the light

Customer reply replied 4 months ago
That is correct what I saw AC and GC wires are both with no current showing on the test light

the clutch switch, brake switch, cruise switch, engine brake, throttle position all feed off of the same splice

those two wires will not show current with a bad clutch switch???
Customer reply replied 4 months ago
The two wires going into the clutch switch, they feed from the ecm???

do you have ground at the clutch switch? wire 97-GH

Ask Your Own Medium and Heavy Trucks Question

If I follow 97AH to the ecm, there should be current on that wire starting at the ecm? Which side of the engine is the ecm located
Customer reply replied 4 months ago
Key on, cruise switch in on position, should be a live current on wire coming from ecm to switch? Correct

no you should have ground, ecm is on the drivers side of the engine

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 4 months ago
My bad, 97gc is the live?? Does that come from?? Where

it is all ground controlled, if you look at the first diagram i sent where all the wires come together in the top right corner at that black square, that is a splice

We checked ground on the wire from the ecm to the trigger switch on clutch pedal, that passed but other side which was the gh wire was dead, so it looks like a faulty switch
