The error code, ATC 000923.01, is generated when the power module (HF) PC6 measures less than 3 volts at the supply voltage for one or both fan motor outputs (lead 0752 and/or lead 0762) while fan motors (M07 and M10) are switched on. This low voltage condition indicates a problem with the power supply to…

The error code, ATC 000923.00, indicates that the power module (HF) PC6 has measured a total amperage in excess of 40 amps at one or more of the fan motor outputs (B1 and/or C3). This high current level typically suggests a short to ground or a defective component within the monitored circuits of the fan…

The error code, ATC 000876.19, is triggered when the output for switching the compressor clutch (M02) is energized by more than one control unit simultaneously. This indicates a communication error or misconfiguration within the CAN BUS system, where multiple signals are conflicting, potentially leading to improper engagement or operation of the compressor clutch.

The error code, ATC 000876.14, indicates that the Automatic Temperature Control (ATC) unit has disengaged the air conditioning (A/C) compressor clutch as a protective measure due to excessive engine heating. This action is taken to prevent potential damage to the compressor and to reduce the thermal load on the overheating engine.

The error code, ATC 000876.12, is triggered when the power module (HF) PC6 detects more than 1 amp of current at the compressor clutch output (lead 2023) while the compressor clutch (M02) is switched off. This unusual current flow indicates a potential short in the circuit or an internal fault within the power module itself,…

The error code, ATC 000876.10, is triggered when the compressor clutch of the air conditioning system is activated more frequently than normal, specifically more than six times per minute. This frequent activation may indicate issues such as an over-cycling condition due to low refrigerant levels, excessive heat load, or electrical faults within the A/C control…

The error code, ATC 000876.09, is triggered due to issues in the data transfer between the power module (HF) PC6 and the ATC control unit. The control unit is experiencing intermittent or nonexistent reception of one or more CAN BUS messages intended for the power module (HF) PC6. This problem could stem from issues such…

The error code, ATC 000876.05, is activated when the power module (HF) PC6 measures less than 350 mA at the compressor clutch output (lead 2023) when the compressor clutch (M02) is engaged. This low current reading typically indicates that the circuit is open, which could be due to a break in the wiring, a disconnected…

The error code, ATC 000876.04, is triggered when the power module (HF) PC6 measures a current exceeding 30 amps at the compressor clutch output (lead 2023) when the compressor clutch (M02) is activated. This high current usually indicates a short to ground within the circuit, which can lead to overheating, potential damage to the compressor…

The error code, ATC 000876.03, indicates that the voltage in the air conditioning (A/C) compressor clutch circuit is excessively high. This condition suggests a potential issue such as a short to a power source within the circuit, which can lead to overheating, damage to the compressor clutch, or failure of electrical components associated with the…

The error code, ATC 000876.01, is triggered when the power module (HF) PC6 detects a supply voltage of less than 3 volts at the compressor clutch output (lead 0732) when the compressor clutch (M02) is activated. This low voltage indicates a potential issue with the power supply, such as a poor connection, insufficient voltage from…
