RESOLVER INITIALIZATION
NOTICE:
Perform resolver initialization and/or learning according to the following table:
Part Replaced or Procedure Performed | Learning | Initialization |
---|---|---|
Inverter with converter assembly | ○ | - |
Hybrid vehicle transaxle assembly | ○ | ○*1 |
*1: If it is necessary to replace the hybrid vehicle transaxle assembly, make sure to perform resolver initialization before starting work.
HINT:
After performing resolver initialization, "Learning not completed" will be displayed on the multi-information display when the power switch is turned on (READY).
Related Data List Data List | Detail |
---|---|
Generator Resolver Offset Value | Displays the resolver learning value. Displays 0 after the inverter with converter assembly has been replaced (and learning has not been performed) or resolver initialization has been performed. Displays the resolver installation offset amount after resolver learning is performed. |
Generator Resolver Offset Complete Status | Displays the completion status of the resolver learning. Displays ON when resolver learning is complete. |
Motor Resolver Offset Value | Displays the resolver learning value. Displays 0 after the inverter with converter assembly has been replaced (and learning has not been performed) or resolver initialization has been performed. Displays the resolver installation offset amount after resolver learning is performed. |
Motor Resolver Offset Complete Status | Displays the completion status of the resolver learning. Displays ON when resolver learning is complete. |
(a) Initialize the learned value.
(1) Turn the power switch off and wait for 2 minute or more.
(2) Connect the Techstream to the DLC3.
(3) Turn the power switch on (IG).
(4) Turn the Techstream on.
(5) Enter the following menus: Powertrain / Motor Generator / Utility / Resolver Learning/Initialization.

Resolver Learning/Initialization |
(6) According to the display on the Techstream, select "Initialization" to perform resolver initialization.
NOTICE:
Do not turn the power switch on (READY) while performing resolver initialization. If the power switch is turned on (READY) and the engine starts, generator resolver learning will be performed and resolver initialization will be canceled.
(7) Check that the generator resolver learning incomplete message is displayed on the multi-information display.
(8) Turn the power switch off and wait for 1 minute or more.
(9) Turn the power switch on (IG).

(a) Resolver Learning
HINT:
If either of the following conditions is met, resolver learning may not be possible:HINT:
After beginning resolver learning, make sure to perform the procedure until resolver learning for both the generator (MG1) and motor (MG2) are completed. (Resolver learning is complete when the resolver learning incomplete message on the multi-information is cleared.)
(1) Turn the power switch off and wait for 2 minute or more.
(2) Connect the Techstream to the DLC3.
(3) Turn the power switch on (IG).
(4) Check that the air conditioning system and power outlet socket are turned off.
(5) Check that the generator resolver learning incomplete message is displayed on the multi-information display.
(6) Turn the Techstream on.
(7) Check for DTCs make sure no DTCs are output.
(If any DTCs which may affect learning are output, resolver learning cannot be performed.)
(8) Enter the following menus: Powertrain / Motor Generator / Utility / Resolver Learning/Initialization.
Powertrain > Motor Generator > Utility Tester Display |

Resolver Learning/Initialization |
(9) According to the display on the Techstream, select "Learning" to start resolver learning.
(10) Turn the power switch on (READY) and wait until the READY indicator changes from blinking to illuminated.
NOTICE:
Do not operate the accelerator pedal, shift lever or any switches until the READY indicator is illuminated.
HINT:
When the power switch is turned on (READY) during resolver learning, the engine will start.
It takes approximately 10 seconds for the READY indicator to illuminate after the power switch is turned on (READY).
(11) Check that the motor resolver learning incomplete message is displayed on the multi-information display.
(12) Move the shift lever to D.
(13) Accelerate the vehicle to between 30 km/h and 40 km/h, fully release the accelerator pedal and allow the vehicle to coast for 3 seconds. (*1)
NOTICE:
Do not operate the accelerator pedal, brake pedal, shift lever or any switches while the vehicle is coasting.
HINT:
If any of the following conditions are met, resolver learning may not be possible:(If the hybrid vehicle transaxle assembly temperature is excessively low, such as (0°C (32°F) or less), the vehicle speed will decrease excessively while the vehicle is coasting. )
(14) Check that the motor resolver learning incomplete message is not displayed on the multi-information display.
HINT:
If the motor resolver learning incomplete message continues to be displayed on the multi-information display, perform step (*1) again.
(15) Stop the vehicle, turn the power switch off and wait for 1 minute or more.
(16) Turn the power switch on (READY).
(17) Check that the generator resolver learning incomplete and motor resolver learning incomplete messages are not displayed on the multi-information display.
HINT:
If the power switch is turned on (IG) after less than 1 minute has elapsed since the power switch was turned off, the learned value may not be stored correctly and the generator resolver learning incomplete or motor resolver learning incomplete message may be displayed on the multi-information display.
