ARC - Armrest Control Unit Diagnostic Trouble Codes

ARC - Armrest Control Unit Diagnostic Trouble Codes
Control Unit SPN FMI Pri. Indicator Light Description Effect
ARC 158 00 2   Battery Voltage High. Control unit outputs are not available.
ARC 158 01 2   Battery Voltage Low. Control unit outputs are not available.
ARC 170 03   Air temperature control Cab Temperature Sensor High. The system response is unpredictable.
ARC 170 04   Air temperature control Cab Temperature Sensor Low. The system response is unpredictable.
ARC 172 03   Air temperature control Inlet (Ambient) Temperature Sensor High. The system response is unpredictable (minimum impact).
ARC 172 04   Air temperature control Inlet (Ambient) Temperature Sensor Low. The system response is unpredictable (minimum impact).
ARC 190 09 2   Engine Speed / Engine CAN Failure. In case of losing communication, low idle is required from the engine as request from the armrest control unit.
ARC 605 04 2 Air temperature control High Pressure Switch. Problem with the refrigerant charge or the air conditioning system.
ARC 628 12 2   Program Memory Failure. Control unit functions not available.
ARC 630 12     No Factory / Dealer Settings. Initial calibration cannot be called back with the reset switch.
ARC 875 04 2 Air temperature control Refrigerant Low Pressure Switch. Problem with the refrigerant charge or the air conditioning system.
ARC 875 14 2 Air temperature control Refrigerant Low Pressure Switch. Control unit function not available.
ARC 919 03   Air temperature control Solar Sensor High - Up to SN 508099. Logic assumes the cab is in bright sunlight when disconnected, which increases the fan speed by approximately 10 %.
ARC 919 04   Air temperature control Solar Sensor Low - Up to SN 508099. Logic assumes complete darkness in cab, which has no effect on the fan speed.
ARC 1547 03 2 Air temperature control Evaporator Core Temperature Sensor High. Duct temperature is used instead, evaporator may be damaged.
