The ATC Advanced Diagnostics control panel allows the technician to see real-time system information on the control panel display. Control panel display will assist in A/C-heater servicing. This real-time information can help the service technician diagnose certain system problems.To display advanced diagnostics, depress ON key three times in rapid succession (fault codes displayed) then immediately press and hold ON key for five seconds. The text "CAB" will be displayed. After a few seconds, the real-time value of the cab temperature measured by the ATC is displayed. This value, as well as any other value displayed by the control panel, will continuously update. Pressing the ON key again repeatedly will scroll through all of the available diagnostics informationCAB - Cab Air Temperature (°C or °F)EVAP - Evaporator Core Temperature (°C or °F)DUCT - Duct Air Temperature (°C or °F)HEAT - Water Valve Command (% of valve open)A-C - A-C Clutch Request (on / off )FAN - Blower Fan Speed (% of maximum fan speed)DEF - Defrost Mode Active (On/Off)HI-P - High Side Pressure (psig or bar)PRHT - Blower Enable Active (On/Off)VOLT - System Voltage (DC Volts)Note: The system can be operated normally while in advanced diagnostics mode, including changing the temperature set point or changing the blower fan speed, to evaluate the response of the system.Firmware Version Mode
The firmware version of the control panel and Electronic Control Unit (ECU) can be displayed. From the advanced diagnostics mode, press and hold the ON key for five seconds. The text CTRL will be displayed and after a few seconds, the control panel firmware version number will be displayed.
