HVAC Code- 126

[Red RoadMonster]

Got a 126 code. Looked through the sticky and there were some guys getting that too, but never was a response as to what that code is for......anyone know?

time to bust out the Factory Service Manual, and see what it says...

I can't find the chart that has the codes. Only thing I can find, is the DTC's for the ABS, and A/C... it's pissing me off, since I have looked for it before. I would now like to murder the maker of the FSM... everytime I come to something that mentions the "On board dianoistics system", it redirects you to a different section, normally in the other book... so I keep switching back, and forth, and I getting nowhere. Bastards...

Well so far only managed to find a HUGE list of Diagnostic Trouble Codes if anyone wants it

The only gm code I could find listed any where is DTC B0126 Right Panel Discharge Temperature Fault. All data does not list any 126 codes for hvac or anything else on my 92 or 94 RML

Well it's the code pulled out of the climate control system not with a code reader. So it's actually like 02-126

I pulled a bunch of codes out of my '93 RMS climate control system, but not sure if '93 year is any good. The numbers for each seam meaningless...

-01 = 48
-02 = 130
-03 = 113
-04 = 109
-05 = 118
-08 = 37
etc...........................anyone able to diagnose these numbers on a '93RMS

According to "Russ," 126 is a equipment does not match code. You will have to call service tech to correct problem. Possible bad outdoor board (whatever that is).

I also have this code and it keeps coming back. Everything seems to be working fine, so I just ignore it. A 1 in front of the code means it happened in the past. 26 is Serial Data Communication? error (shorted/open). Codes prefixed by a "1" are history codes. A code can be cleared by pressing the "OFF" button while that particular code is being displayed. Mine always eventually comes back.

So is there a fix or should someone just not worry about it?
