code 8c.... it gets better!!

740-09-bb14044... non cold storage...fore aft stance with the optional 2nd control handle...less than a 1,000 hd hours.
I know this is what most of us call a nuisance code (deadman pedal signals do not agree) but this one is driving me up a wall!
If you step into the truck & drive it facing the forks there is no problem it will run all day! BUT!!! if you turn around & face the back (to use the 2nd control handle) as soon as you step on the deadman it codes! It makes no difference how fast or slow you step on it or where your foot is placed.
So far I have replaced the bushings in the pedal shaft & the main pedal mounting bracket. It passes all the tests, the sensor & switch have both been replaced. The pedal height & switch are adjusted to factory specs (checked & rechecked many times) one of the guys even tried a vehicle manager (no help) I am back there again tomorrow morning. Has anyone else run into a similar problem? I am close to telling the customer to call a priest & have him drive the demons out...LOL because the truck seems like it is possessed!

I worked on these a few times. The deadman pedal issue is that, an issue, not sure if they have come up with a service bulletin.

I would ask about the 2nd handle though. Have you checked it out? I had a few with pots out of whack, caused all sorts of issues unti lwe worked it out, and they did not always come up as handle faults

Fact of the week
In March 2002, identical twins in Finland died on the same day in similar accidents within hours of each other. A 70-year-old man was killed by a truck while cycling; hours later, his twin brother was killed by a truck on the same road, about a mile away, before the family had been informed of the first accident.
