-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- With the vehicle stopped and the shift position in P, turn the power switch on (IG) and wait for at least 70 seconds. [*1]
- Turn the power switch on (READY) and without depressing the accelerator pedal, and while depressing the brake pedal, change the shift position to D and wait for 1 minutes. (Step A)[*2]
- Drive the vehicle 0.5 m (1.6 ft.) forward and perform step A.[*3]
-
Drive the vehicle another 0.5 m (1.6 ft.) forward and perform step A. Repeat this procedure 5 times (minimum total driving distance: 2 m (6.6 ft.)).[*4]
HINT:
[*1] to [*4]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:

CAUTION / NOTICE / HINT
CAUTION:
-
Before the following operations are conducted, take precautions to prevent electric shock by turning the power switch off, wearing insulated gloves, and removing the service plug grip from HV battery.
- Inspecting the high-voltage system
- Disconnecting the low voltage connector of the inverter with converter assembly
- Disconnecting the low voltage connector of the HV battery
-
To prevent electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle.
-
After removing the service plug grip from the HV battery, 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.
Click here
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
-
Make sure to insulate the high-voltage connectors and terminals of the HV battery with insulating tape after removing it.
If the HV battery stored without insulating the connectors and terminals, electric shock or fire may result.
-
When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.
*a
Dealer
*b
Battery Collection Agent
- Accidents such as electric shock may result if the HV battery is disposed of improperly or abandoned. Therefore, make sure to return all HV batteries through an authorized collection agent.
-
Before returning the HV battery, make sure to perform a recovery inspection.
Click here
-
Before returning the HV supply stack sub-assembly, make sure to perform a recovery inspection.
Click here
- Make a note of the output DTCs as some of them may be necessary for recovery inspection of the HV battery and HV supply stack sub-assemblies.
-
After removing the HV battery, keep it away from water. Exposure to water may cause the HV battery to produce heat, resulting in a fire.
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.

HINT:
P0E2D00 may be output as a result of the malfunction indicated by the DTCs in table below.
- The chart above is listed in inspection order of priority.
- Check DTCs that are output at the same time by following the listed order. (The main cause of the malfunction can be determined without performing unnecessary inspections.)

NOTICE:
- Make sure to check the polarity of each terminal (positive (+) or negative (-)) before connecting a tester.
- Read the resistance after the value has stabilized.
- In order to avoid damaging the terminals of the battery ECU assembly, make sure to use tester probes with a diameter of approximately 0.5 mm (0.0197 in.) when measuring the resistance of the battery ECU assembly.
(c) Install the battery ECU assembly.

SIMULATION TEST |
NOTICE:
Do not turn the power switch off while performing this inspection.
(a) With the vehicle stopped and the shift position in P, turn the power switch on (IG) and wait for at least 70 seconds.
(b) Turn the power switch on (READY) and without depressing the accelerator pedal, and while depressing the brake pedal, change the shift position to D and wait for 1 minutes. (Step A)
(c) Drive the vehicle 0.5 m (1.6 ft.) forward and perform step A.
(d) Drive the vehicle another 0.5 m (1.6 ft.) forward and perform step A. Repeat this procedure 5 times (minimum total driving distance: 2 m (6.6 ft.)).
(e) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
(f) Check if DTCs are output.

CHECK INVERTER WITH CONVERTER ASSEMBLY |
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) Disconnect the motor cable from the inverter with converter assembly. HINT: Make sure that no foreign matter, coolant or water enters the inverter with converter assembly. |
|
|
(c) Using a megohmmeter set to 500 V, measure the resistance according to the value(s) in the table below. NOTICE: Be sure to set the megohmmeter to 500 V when performing this test. Using a setting higher than 500 V can result in damage to the component being inspected. Standard Resistance:
HINT: Perform this inspection with the motor cable disconnected from the inverter with converter assembly. |

CHECK HYBRID VEHICLE TRANSAXLE ASSEMBLY (MOTOR CABLE (FOR MG2)) |
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) Disconnect the motor cable from the inverter with converter assembly. HINT: Make sure that no foreign matter, coolant or water enters the inverter with converter assembly. |
|
(c) Connect the cable to the negative (-) auxiliary battery terminal.
HINT:
As the insulation resistance may vary when motor (MG2) rotates, perform this inspection while rotating the front wheels.
(d) Turn the power switch on (IG).
NOTICE:
Turning the power switch on (IG) with the service plug grip removed causes DTCs to be stored. Clear the DTCs after performing this inspection.
(e) Move the shift lever to N and lift the vehicle.
(f) Turn the power switch off.
|
(g) Using a megohmmeter set to 500 V, measure the resistance according to the value(s) in the table below while rotating the front wheels 2 revolutions in the same direction simultaneously. NOTICE:
Standard Resistance:
