ended up being the arm on the accelerator switch would not stay in contact with the foot pedal. have no idea why all the sudden was not staying in contact as arm was not broken and of course no one touched or adjusted anything. i moved the switch bracket forward alittle and bent the arm a little to make the error go away. all is well.
thanks for the advice everyone.

First off make sure the directional lever is in neutral and the accelarator pedal is all the way up, nothing binding it or holding it down BEFORE YOU TURN ON THE KEY.

Now this unit does have a diagnostics test you can run it through using a switch called a DRS switch which is located on the logics card or somewhere near it on the control panel. You would need the diagnostic chart to know how to use this method to know which tests it wants to run in the order it runs them before even considering using this diagnostic method.
You would put the truck in diagnostic mode using the DRS switch and then use the switch to cycle through each test, without the chart to guide you it would be a long and terrible guessing game to figure out for you.

Now there is an old school way to do it:

The error code explains it as the directional lever and accelerator have a faulty setting. It could be one or the other.
It explains either one as such:
directional lever- is not in neutral (circuit is not detecting a neutral signal)
accelerator- is not 0 when power is turned on.

Now you either have a directional lever switch that is not functioning correctly and is shorted in one directional setting and not actually returning to neutral state when the lever is moved to neutral OR the accelerator is not returning to 0 when the pedal is released.
when the key is turned on the logic self checks the system and looks to make sure the pedal is not pressed and the directional lever is in neutral state, if it sees any signal other than that it triggers the E on the display.

You can use a vom and disconnect the directional lever at connector CN6 on the logic card and check terminal wires 102, 103 and 105.
The schematic diagram shows wire 102 as a white wire on terminal 21 in the ground circuit, wire 103 is an orange wire on terminal 5 in the forward circuit and wire 105 is a Brown wire on terminal 6 in the reverse circuit.
from plug CN6 at the logics put the negative vom lead to white wire 102 and positive lead to orange wire 103 to check forward, move the positive lead to Brown wire 105 to check the reverse circuits.
You can also leave the connector plugged into the logics and use neg terminal 102 and pos to terminals 103 and 105 and check voltage readings, with circuit open it should read 15v, with directional lever activated the voltage should drop low.

If you find any bad readings or flaky readings when you select the direction your checking then the switch is faulty and should be replaced.

To check the accelerator circuit disconnect the connector plug CN7 at the logics.
The accelerator switch wire 143 and is lavender color on terminal 14, the positive 5v wire 142 is red on terminal 39, the pedal angle sensor wire 141 is green on terminal 33, and the ground wire is lavender wire 144 on terminal 37.
to check the start switch put vom leads between terminals 14 and 37, both lavendar wires.
To check the pot readings put vom leads between lavendar wire on terminal 37 and green wire terminal 33, this should show you the ohm range of the pot while moving the pedal, you're looking for a range of 0 to 4.7k ohms i think.

You can also leave the connector CN7 plugged in and check voltage at terminal 142, with pedal up it should read 0v, when the start switch is activated it should read from 0.9v to 4.7v when fully pressed.
If you see any anomolies in the readings try to adjust, if no change or the desired readings are not seen in the pot then replace the pot or the acclearator assy.

If you do not find ANY problem with either then the logics is bad, it will have to be replaced.

ok.. since its solid. check to make sure that the accelerator pedal is not stuck down a little or stuck. if not trouble shoot the accelerator. trouble shoot the forward/reverse lever and wiring. you can use self diagnosis to check these do you have a book? if all check good replace logic card.

is it a flashing E or solid E? first off check the seat switch and wires
