Thanks Steve Huber, its getting a new computer module. Please delete post.

TC,
Pages 29-30 of the 2006 Monterey Wiring Diagrams in Coach Assist contain the Aladdin - Engine Date wiring. It's a twisted pair from the engine ECU to the Aladdin.
Just curious, what problem is the tech working on?
Thx, Steve

The transmission is working but the “check trans’ light is on and it doesn’t show a gear just an icon saying it needs service no error codes. Aladdin says no voltage.
Tech is on vacation until next week I’ll get that into to him. THANK YOU. I really need to sell it.

TC,
I suspect that the Aladdin is simply showing what it is receiving. The problem would seem to be in the transmission / tranny ecu to Keypad wiring.

TC,
It sounds like your problem may be in the transmission ECU. If the Trans Check indicator stays on, the ECU has detected an error and stores the code. If there's no code, the ECU may be at fault. Be sure the tech is using the correct procedure to read the codes at the keypad. Press the up and down arrows together twice to access the codes. (Once will display oil info). Use the mode button to scroll through the codes. If the Mode button is pressed for 10 sec it will clear the codes. Also,have the tech check the cable connections at the transmission. Due to the environment they are subjected to, they can give one problems with faulty connections.

The Alison troubleshooting manuals are in the coach assist library.
They should be cable to walk you tech through the proper diagnoses and repairs
As Steve said the first thing to do is retrieve the stored diagnostic code/s and work from there .
Good luck
