ISL 400 error 233 12 controller 2

[Dupdyke]

2003 dynasty isl 400 running vmspc V3. I get a logged error message
"122 12 controller #2" error message and my shifts are not crisp and smooth.

I can not find any references in cumins or allison lists of errors. Anyone else seen this message. I am in the middle of the north woods in mn and will not get to anywhere that has a mh friendly shop until wensday.

This is what I found for engine fault code 122. Intake manifold pressure sensor shorted high. Engine will de-rate to no boost. The matching pid should be p102 and FMI 3 or 4. The VMSpc should give a plain english decode for engine faults. I could not find an Allison code but suspect that might be your problem.

Use your keypad to read the codes from the allison. See page 41 of your operators manual.
I did notice the 233 code in the title just now. That decodes to ABS controller #2 ??
