"Cooling Fan Frequency2" is detected when the battery cooling blower assembly LH is operating and its value changes in proportion to the battery cooling blower assembly LH speed.
If the battery cooling blower assembly LH speed is excessively high, this DTC is stored.
WIRING DIAGRAM
Refer to the wiring diagram for DTC P0A84-123.
CAUTION / NOTICE / HINT
Before inspecting the high-voltage system, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work.
Tip:Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work.
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
-
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Powertrain / Hybrid Control / Active Test / Driving the Battery Cooling Fan.
Select fan mode 6 and operate the battery cooling blower assembly LH.
Operation of the battery cooling blower assembly LH can be confirmed by checking if air is sucked into the air intake port of the intake duct.
