HINT:

"Hybrid/EV Battery Cooling Fan 1 Frequency" is detected when the battery cooling blower assembly is operating and its value changes in proportion to the battery cooling blower assembly rotation speed.


MONITOR DESCRIPTION

If the battery ECU assembly detects that the speed of the battery cooling blower assembly is outside the normal operating range, it will illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN

HINT:
·

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>HYBRID BATTERY SYSTEM>UTILITY

·

When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

Click hereEngine / Hybrid System>HYBRID / BATTERY CONTROL>HYBRID BATTERY SYSTEM>DTC CHECK / CLEAR



1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON and turn the GTS on.

3.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4.

Turn the ignition switch off and wait for 2 minutes or more.

5.

Turn the ignition switch to ON (READY) and turn the GTS on.

6.

Enter the following menus: Powertrain / HV Battery / Active Test / Control the Hybrid/EV Battery Cooling Fan.[*1]

7.

Operate the battery cooling blower assembly in each fan mode, 1 through 6, for 60 seconds or more.[*2]

HINT:
·

Operation of the battery cooling blower assembly can be confirmed by checking if air is sucked into the air intake port of the intake duct.

·

[*1] to [*2]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.



8.

Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.

9.

Check the DTC judgment result.

HINT:
·

If the judgment result shows NORMAL, the system is normal.

·

If the judgment result shows ABNORMAL, the system has a malfunction.

·

If the judgment result shows INCOMPLETE, perform the normal judgment procedure again.
