SERVICE PROCEDURE:
1.
Depress the brake pedal and press the Start button two times to activate "EV Ready" mode .
Attach a GOS , check for OTC in the "MCU " menu. Record the DTC and description.
Check the Freeze Frame data to check the Drive Motor Temperature when
the OTC was set.
Delete the OTC .

Open the rear trunk and open the cover to the
safety switch .
Put on safety gloves and pull up on the black
tab and pull out the safety switch .
Go to Step 4 .
WARNING
Failure to perform this procedure may
result in accidental injury or death.
4.
Without depressing the brake pedal , push the Start-Stop button 2 times to power the cluster.
Attach a GOS and select BMS menu , Current Data and Inverter Capacitor Voltage . Confirm
the Inverter Capacitor Voltage is less than 30V.
•
•
If less than 30V, the system voltage is safe for the technician . Turn off the ignition and
disconnect the negative battery cable . Go to Step 5.
If more than 30V, wait until the voltage is within specification before performing any
repai rs.

Use a DVOM to measure the resistance
between the two pins shown . Record the
resistance .
Specification :
9.
Disconnect the extension motor wire connector
to the temperature sensor at the transaxle.
Measure the resistance between the two pins
shown . Specification :
If the resistance is:
• Different than the value found in Step 8, go
to Step 10 and retest the extension wire.
• Not within specification , replace the
automatic transaxle and go to Step 11.
• Within specification , replace the HPCU.
10. If Step 8 and 9 showed different values , use a
DVOM to measure the resistance between the
pins as shown. If the resistance is:
• Less than 1 ohm , the harness is ok. Go
to Step 9 and retest.
• More than 1 ohm , replace the extension
motor wire .

If transaxle was replaced , remove the fill plug.
Filling and checking of fluid level is
done through valve body side cover
Use a funnel to add approximately 5-6 quarts
of SP-4-M ATF through the fill plug opening .
Reinstall the fill plug .
Attach the GOS to the DLC and select vehicle ,
A/T menu , Cu rrent Data and "Oil Temperature
Sensor".
Start the eng ine and shift to Park. When the
ATF is 122°F-140°F (50-60 °C), remove the
level checking plug . The level is correct when
oil flows from the level checking plug in a thin
steady stream .

Collect and dispose of any excess fluid in accordance with local regulations.
12. Clear the OTC in the Bluelink system according to instructions in TSB 12-BE-005-2.
13. Drive the vehicle for two key-on/key-off cycles to confirm the OTC do not return . If the OTC
return , repair or replace the control wiring harness .
