ALLISON failure on '01 Intrigue...ideas?

Yahoo Message Number: 50773
We're in an Allison repair place, but so far, they've not figured out the cause of our failure this morning. Symptoms: leaving RV park all went well for a few minutes. Just as we were entering the road, the Transmission light went on. Then, no power when the gas pedal was depressed. Then NOTHING appeared on the transmission panel. We were able to coast to the edge of the road. Couldn't restart the rig. Towed to the repair facility, but they have found (in two hours) that they can't get power to the Allison at all. It's not being read by their puter. No power, no readout, etc.

Has anyone had this happen and have any clues we can give them? Thanks...

There is a fuse direct from the chassis batteries that powers the ecu... it is a good possibility this fuse has blown or the wire has fallen off the battery due to corrosion etc... The ecu has to have power even when the key is turned off.

Its a smart bet its not the Allison*; sounds like the engine ECU is involved which makes it a 12V issue. They need to start w/the basics for 12V grounds and other connections which is simple but detailed following of the wiring. I'm assuming they've checked the 6 wiring connections to the Allison or else they wouldn't be a real Allison joint. Mike *Hint- its virtually never the Allison.

We had similar symptoms where our rig when into 'limp' mode twice while driving and then a third occurrence after parking at a RV Park entrance for 20", the Allison panel wouldn't light up and the rig wouldn't start.
After the first two occurrences, the rig restarted after waiting 60 minutes and 6 hours respectively.
We had two visits to Cummins NW who didn't accomplish anything except bill us about $500 per visit.
A park neighbor told us he had the same problem and it was his chassis battery so we replaced ours (it was of an unknown age but I estimated 3 years old) and drove to an Allison service center in Ridgefield, WA. They thought we didn't have a good ground to the transmission electronics so they ran new wires from the batteries in the back to the front electronics.
At this point, I don't know if it was the new battery or the wiring but we've gone two months with no problems.

Thanks for all the input. The result was that we decided to get towed to the Allison place west of St. Louis (in Wentzville...the Clarke service place)...170 mile tow, but in 10 minutes the Allison tech had figured out it was the ECU unit and had us out of there in an hour! Worth the tow! CoachNet dropped the ball for us on this one. They sent us to a place initially where the service fellow told them they no longer had an Allison tech there. CoachNet told them to try anyway. Net result was 3 hours of labor for us with no results. (In spite of your "hints" I gave them.) The tech said we MUST go to St. Louis where they could fix us. Called CoachNet and told them they should have taken us to a place that could do us initially. They agreed to tow us to another place 80 miles away, but we decided to go for the BIG service place. Glad we did...cheaper in the long run!
If you ever need a tow in the Sikeston, MO area...remember Satterfield Towing...fabulous! VERY careful and knowledgeable.
Also Clarke's in Wentzville for engine and transmission etc. is terrific. Huge, clean shop, can service Cummins and Allison...large parts dept.

Now we're back on schedule with our group heading to Nova Scotia.

Currenty, have same problem with 2004 Intrigue. i lost all power to trans while parked. Local Allison helped by phone in having me check pins 1, 16, 17 and 26 9n gray connector at Allison computer in front steering bay. No voltage on pin 26. ??? cause and what to do. What did they find on your coach?

I have heard stories of power supply failure in the Allison control module, but what I understand it is in the older rigs caused by age. Wonder if this the same failure but not so much old age related. There is some one in Texas who repairs them for around $300.

Loose connection at the black box in the compartment directly under the driver. The plug connector came partly loose. My symptoms were the same,

Dr. Robert:

Jan had posted that they were going to sell their CC so she may not be reading these posts.
She had e mailed me that they had it towed from Sikeston to St. Louis where the problem was found in 10 minutes.

The ECU unit had failed. This may or may not be your problem.
I think you can get the same symptoms when the Starter Solenoid fails but one of the CC Techs on this group can respond to that.

Richard,

Thank you. Just to be complete, when I discovered that I had no voltage at the starter solonoid, I just used a jumper from the battery to the solonoid and started the engine. What I can't figure out, is where is the 12v feed to the Allison computer and where is it fused. Allison can't go any further since I have found that there is no voltage on pin 26. Does anyone know where the fuse and or circuit is to the Allison system. I can't find that circuit in the manual or on the coach.

This is just a wild guess.

There is also a Starter Solonoid in the front of the coach. Mine is behind the panel in front of the passanger seat. This is to supply power to things since the run fom the front to the back of the coach is so far. If that solonoid is bad you will get nothing when you turn the key on. No lights to transmission key pad, dash lights, silverleaf, and I don't think even the dash guages will work.
There has been much discussion recently about this solonoid that is in the front. If it goes bad I know weird things will occur.

Again, just a guess.

Richard

Hi Dr.,

I have posted a copy of the Allison Troubleshooting Manual in the files section here or you can download a free pdf of it from my website (www.accws.com) under free service downloads. It has pictorals of all connections and wiring for your trans.

Thanks,
