The following items can be helpful when performing repairs:
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.

HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
*a | Without waiting for 10 minutes |
NOTICE:
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.

PROCEDURE
1. | CHECK DTC OUTPUT (HV BATTERY, HYBRID CONTROL) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: Powertrain / HV Battery and Hybrid Control / Trouble Codes.
(d) Check for DTCs.
Powertrain > HV Battery > Trouble Codes Powertrain > Hybrid Control > Trouble Codes Result | Proceed to |
---|---|
P0A8196 only is output, or DTCs except the ones in the table below are also output. | A |
DTCs of hybrid battery system in the table below are output. | B |
DTCs of hybrid control system in the table below are output. | C |

2. | CHECK DUCT AND BLOWER |
CAUTION:
Be sure to wear insulated gloves.
(a) Check that the service plug grip is not installed.
NOTICE:
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.
(b) Remove the rear seat cushion leg sub-assembly.

(c) Check that the No. 1 HV battery intake filter, battery cooling blower assembly and No. 1 hybrid battery intake duct are not disconnected, damaged, or clogged with foreign matter.
*1 | No. 1 HV Battery Intake Filter | *2 | Battery Cooling Blower Assembly |
*3 | No. 1 Hybrid Battery Intake Duct | *4 | No. 1 Hybrid Battery Intake Duct LH |
OK:
The No. 1 HV battery intake filter, No. 1 hybrid battery intake duct, No. 1 hybrid battery intake duct LH and battery cooling blower assembly blower are not disconnected, damaged, or clogged with foreign matter.
(d) Install the rear seat cushion leg sub-assembly.
