05 = evaporator sensor
06 = Engine coolant temperature
07 = refrigeration pressure in bar
08 = refrigeration temp sensor

11 = emissions sensor (Bsp.: 3.1 = 31.v)
12 = sun sensor (Bsp.: 4.2 = 4.2v)
20 = aux cooling fan control 6.1 = 6.1ma (max 10ma)
21 = engine speed RPMs x 1000
22 = vehicle speed KPH
23 = Circuit (Bsp.: 99 = 99% of battery voltage)
24 = BATTERY VOLTAGE (Bsp.: 12.5 = 12.5v)
40 = control module version software status
41 = control module version menu hardware status
42 = control module variant code 1st number
