N22 Read-Out Values
Via (Climate) Control Module

1. In-car termperature sensor (with aspirator blower)
2. Outside temperature sensor
3. Heater core temperature sensor
5. Evaporator temperature sensor
6. ECT sensor (Coolant temp.), e.g. 12*5 = 125C
7. Refrigerant pressure in bar, e.g. 12*8 = 12.8 bar
8. Blower control voltage, e.g. 16*5 = 1.65 volts
9. Software status of A/C pushbutton control module
15. Selected in-car temperature
20. Version code
21. Engine Speed (RPM), e.g. 6*0 = 600 rpm
22. Terminal 58d (Bat. Volt.), e.g. 99.0 = 99% of voltage
23. Vehicle speed (Kilometers Per Hour)
50. Not used 00
51. Number of current slip recognition (poly-V-belt)
52. Number of stored slip recognitions (poly-V-belt)

This code system works for my 95 C280 (produced 10-94), it's not supposed to work for models earlier than 95, but give it a try anyway.

This is what I typed and laminated so I will have a "quick reference" card in my car!! HAHA This was kind of a mix between 2 different version codings, but it works exactly for my car. I have 2 lists, so if you want any other codes, or some are wrong on yours, just let me know and I'll look them up to see if I can help you. Again, thank STEVE for all this!!!
