John - I've got an 88' with DDEC1 as well. Shortly after purchasing I started getting flashing engine codes. Oil pressure sender was bad; replaced that - then kind of OK, but still flaky. In any case, per reading other posts here on the WOG, decided to run new/dedicated power and grounds to both ECM/PCM. Local WW Williams did this... so don't know all the details on how. They also found one of the connectors going into the control box on top of the motor (I think that is PCM... but could be ECM)… they cleaned up that connector and added some tie-wraps to help support the connection into the box and keep it from pulling on the connector. Since running those dedicated power/ground and cleaning up connector into the box, it has run flawless ever since. S

Sounds like your problem may be a bit different... but if you haven't run dedicated power/ground yet, that may cure some of your ills.

Attached is my service request to WW Williams along with post from WOG.

All,

I'll try contacting some of the links you have all provided (thanks!).

Looking at the diagrams (linked to) it doesn't show the communications between the DDEC and the ATEC but they are there. My DDEC main code is saying it can't talk to the ATEC and the ATEC is flashing a code saying it can't talk to the DDEC.

I dug around and found wiring diagrams for both connectors and rang the 4 comm wires between the units (Canbus I believe) and all were good. As there was 2 other codes the Detroit tech pulled, I am assuming it must be the DDEC and not the ATEC causing the issue. That and what I have read online from people is that the ATEC is fairly bulletproof.

I'll post any updates. thanks for the info so far!

John

I suppose that means you also checked to make sure that none were shorted together and that none were shorted to ground?

I also ran new power and grounds to the EDU (the box on the engine) and it made all of my crazy check engine light flashing go away.

53 sure sounds like the TRS. In the downloads section there a DDEC I Troubleshooting guide. It will take you step by step to resolve each engine code.

From the Guide:

Code 53. ECM Failure - The ECM has detected a failure in its internal circuitry used to process the TRS signals.

Step 1 of the guide says "Replace the ECM".

we had a wogger last year that had the same issue,they were a long way from home and they left the coach to be repaired,i think it was a year before the dealer fixed it.
They did replace the ecm,and they did get it running.


the owner picked it up and it happened again.
he wiggled the wires under the dash and it started.
he had a bad connection in a canon plug,it cost him major money to have it "fixed".
