Default Tach in the Climate Control & Trouble Codes.

Did you know that you can access your Engine(and other) trouble codes thru the Climate Control? Did you also know that you can accurately monitor the engine RPM, vehicle speed, coolant temp, and others? If so, good job! If not, look at this!

This is for 94-96's!!



*Please note, some of this was info copied directly from ISSF.



Instructions for putting ACC in diagnostic mode -
- turn ignition to ON position (or start vehicle)
- press and hold the "temp up" and "OFF" buttons at the same time until the unit does a full segment check.
- Release the buttons.
- Display should read -00... you are now in diagnostic mode
- Using the fan up/down buttons, select desired function from above
- press the "middle" Button. It should be in the top right corner on the CC.
- To Exit the trouble code area, and go back to the -00 display, hit the "Middle" button again.

Have fun!

You will see -00. You can change the funtion(it will say -01, -02, etc) with the fan up, and down buttons. Here is a list of what all the -00 numbers mean.


Here are the most common you will need to know

-00 PCM diagnostics codes
-01 CCM Diagnostic trouble codes
-02 HVAC Diagnostic trouble codes
-03 SIR Diagnostic trouble codes
-04 ABS/TC Diagnostic trouble codes
-06 Engine RPM
-08 Coolant Temp (°F) - Reading taken at Cylinder head sensor, typically 20* cooler than the -24 reading
-14 Vehicle speed
-24 Coolant Temp (°C) - Reading taken at the Water Pump sensor, This is what the PCM uses to control the fans.



Diagnostic Pointers and Parameters

No. Description Range Default Value Units


-00 PCM System Diagnostic Trouble Codes ...............................................
-01 CCM System Diagnostic Trouble Codes ...............................................
-02 ACAC (HVAC) System Diagnostic Trouble Codes .......................................
-03 SIRSystem Diagnostic Trouble Codes ................................................

-20 Current Temperature Valve Position ...... 0-255 ....... 240 ............. Counts
-22 Temperature Valve Position (Full Cold) .. 180-250 ..... 180 ............. Counts
-23 Temperature Valve Position (Full Hot) ... 5-60 ........ 60 .............. Counts
-24 Engine Coolant Temperature .............. -40 to 151 .. n/a ............ Celsius
-25 Command Temperature Valve Position ...... 0-255 ....... 128 ............. Counts

But what if the ECC head unit in your 1996 caprice, was removed from a 1994 Roadmaster.

Will it still work?

I don't see why not, if it is wired up properly, which I'm sure you did.

This was other guys info, I had put on BuickFourms, from here. So now I was just putting it back.

Well to continue on my 92 Roadmaster limited after accessing the diagnostic menu in my climate controll some stuff seems the same and some stuff is different like for example on -02 Im getting readings and they change and its higher than the codes posted above so im thinking maby temp for something..My menu only goes up to -24 and some just stay at 00..Is there a difference in the displacment in codes for my 92 rather than the 94-96 or can I get pcm and ccm readings at all on my 92??thx
