 If the 251802-1570 CPU chip on this board, which acts as the primary processing unit for the A/C system's electronics, is broken, you can expect several issues that could affect the operation of the air conditioning system:

Complete Failure of A/C System:
The A/C might not turn on at all or could fail to function properly. Since the CPU is essential for managing the various functions and settings, its failure could prevent the entire system from operating.
Loss of Temperature Control:
The system may not be able to adjust the cabin temperature accurately. The CPU usually processes sensor data to maintain the set temperature; if it's damaged, the system won't be able to interpret or react to these signals correctly.
Fan Malfunction:
The fan speed regulation could be affected, causing the blower to run at full speed constantly, not at all, or intermittently.
Defrost/Mode Functions Disabled:
The defrost feature and other mode selections might not work, as the CPU controls the switching between different modes.
Compressor Control Issues:
The compressor, which is critical for cooling, may not engage or disengage properly, leading to insufficient cooling or overheating.
Error Codes:
Diagnostic trouble codes related to the A/C system may appear on the vehicle's dashboard or during an electronic diagnostic scan.
Intermittent Problems:
The system might work sporadically, functioning one moment and failing the next, making troubleshooting more challenging.
Impact on Related Systems:
In vehicles where climate control is integrated with other systems (e.g., seat heating, ventilation), the malfunction of the CPU could also affect these linked functionalities.
The above faults can be solved using our TOYOAC.
