DTC P0AD3 Hybrid Battery Pack Cooling Fan 3 Control Circuit High

DESCRIPTION

DTC Detection Condition:

Speed of the battery blower assembly is controlled by the HV control ECU. Battery blower assembly power is supplied from the FCTL1 terminal of the HV control ECU by the battery blower relay when it is turned on. The HV control ECU adjusts command signals (S0, S1 and S2) to each battery blower assembly to get the fan speed corresponding to the HV battery temperature. Information of the voltage applied to each battery blower assembly (VM0, VM1 and VM2) is sent to the HV control ECU as a monitor signal via serial communication by the battery smart unit.
