NG → CORRECT THE PROBLEM 

OK: Go to next step 

1. Disconnect the cable from the negative (-) auxiliary battery terminal.
2. Check that the service plug grip is not installed.
   NOTE:

   After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair information because this may cause a malfunction.

3. Disconnect connector A19 from the power management control ECU. Refer to REMOVAL .
4. Disconnect connector Q14 from the battery cooling blower assembly.

   NOTE:

   When taking a measurement with a tester, do not apply excessive force to the tester probe to avoid damaging the holder.

6. Connect the battery cooling blower assembly connector.
7. Connect the power management control ECU connector. Refer to INSTALLATION .
8. Connect the cable to the negative (-) auxiliary battery terminal.

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Remove the power management control ECU. Refer to REMOVAL .
2. Measure the resistance according to the value(s) in the table below.

3. Install the power management control ECU. Refer to INSTALLATION .

NG → See step   9 

OK: Go to next step 

1. Check that the service plug grip is not installed.
   NOTE:

   After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair information because this may cause a malfunction.

2. Connect the Techstream to the DLC3.
3. Turn the power switch on (IG).
   NOTE:

   • After removing the service plug grip, do not turn the power switch on (READY) unless instructed by the repair information because this may cause a malfunction.
   • If the power switch is turned on (IG) with the service plug grip removed, DTC P0A0D-350 for the interlock switch system will be stored. If this DTC is output, clear the DTC using the Techstream. Refer to DTC CHECK / CLEAR .
4. Enter the following menus: Powertrain / Hybrid Control / Active Test / Driving the Battery Cooling Fan.
   NOTE:

   If the Active Test cannot be performed, skip it and proceed to the next step to check voltage. In accordance with fail-safe system operation, the power management control ECU sends a command to operate the battery cooling fan.

5. Enter the following menus: All Data / VMF Fan Motor Voltage 1.
6. Select each air volume mode (1 to 6) in the "Driving the Battery Cooling Fan" Active Test to operate the battery cooling blower assembly.
7. While the cooling fan is operating, compare the value in the data list (VMF Fan Motor Voltage 1) with the voltage value that was actually measured at the battery cooling blower assembly connector.

   Standard

   Tester Connection	Condition	Specified Condition
   Q14-2 (VM0) - Q14-4 (GND0)	Battery cooling blower is operating	Difference between the value in the Data List (VMF Fan Motor Voltage 1) and the actual measurement value is 1 V or less.

   *a	Component with harness connected (Battery Cooling Blower Assembly)

   HINT: 

   Compare the values in each air volume mode (1 to 6). If the active test cannot be performed, compare the values only in the current air volume mode.
