HELP! stuck in Wisc - need wiring diagram for 88-89 DDEC I

[jqrjr]

Ken,

I hope that you are again on the road. I have a 88WBWLXXV DDEC1 I
have had many codes with the engine. The unit "remembers" old codes
even if problem has been resolved. You need to kill the power in the
coach with the kill switch in the back of the Coach. this kill the
power to the "memory" for the error codes in the DDEC1. If in truth
you have solved the problem then you will get only the 2 5 code
meaning everthig is OK. I was having a simmilar problem I founfd that
it was the cooling sensor on the Drivers side in the engine bay by
the coolant res. Loose connection! reseated, reset DDEC1 25 code on
down the road.

Someone suggested that you update to DDEC4 I have gotten this
suggestion also..MY DD dealer has little idea of what to do with a
DDEC1, they don't have a reader, they seem to have gotten a little
better after a call to DD main office, but the guy that works on it
was born in 1984 the engine 1s 1986.

to Antigo Wisc yesterday (Friday) to have the new slide outs
installed in ToWanda's bays when our "Check Engine" light came on and
she cut to half power. All gauges were reading just fine when the
light came on. She restarted for us and we were able to get her over
to River States Truck & Trailer. She ran fine, all gauges reading
normal, no power problems, just the Check Engine Light being on was
the only indication of a "problem."

Check Engine light remains on. It appears to be a problem with
wiring going to the sensor. River States is trying to track down a
wiring diagram from Detroit for us.
