·

Check "All Readiness" after simulating malfunction symptoms or for validation after finishing repairs.

CHECK FOR DIAGNOSIS RELATED INFORMATION

CLEAR DIAGNOSIS RELATED INFORMATION

RESOLVER INITIALIZATION

NOTICE:

·

The resolver learned values cannot be initialized by disconnecting the cable from the negative (-) auxiliary battery terminal or removing a fuse.

·

If resolver learning is not performed after the inverter with converter assembly, a part related to the hybrid transaxle assembly or a part related rear traction motor with transaxle assembly has been replaced, the following DTCs may be stored and the symptoms may occur:

-

DTC output

P0BFF1D (Drive Motor "A" Circuit Current Out of Range)

P0C1900 (Drive Motor "A" Execution Torque Performance)

P0C7917 (Drive Motor "A" Inverter Voltage Sensor (VH) Circuit Voltage Above Threshold)

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 display is cleared.)

i.

Turn the ignition switch off and wait for 2 minutes or more.

ii.

Turn the ignition switch to ON.

iii.

Check that the air conditioning system and power outlet socket are turned off.

iv.

Check that the generator resolver learning incomplete message is displayed on the multi-information display.

v.

Check for DTCs. Make sure no DTCs are output.

(If any DTCs which may affect learning are output, resolver learning cannot be performed.)

vi.

Enter the following menus.

Powertrain > Motor Generator > Utility

Tester Display
Front Resolver Learning/Initialization

vii.

According to the display on the GTS, select "Learning" to start resolver learning.

viii.

Turn the ignition switch to 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 ignition switch is turned to ON (READY) during resolver learning, the engine will start.

It takes approximately 10 seconds for the READY indicator to illuminate after the ignition switch is turned to ON (READY).

ix.

Check that the motor resolver learning incomplete message is displayed on the multi-information display.

x.

Move the shift lever to D.

xi.

Accelerate the vehicle to between 30 km/h (19 mph) and 40 km/h (25 mph), 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:

·

A shift state other than D position.

·

The vehicle speed is excessively low or high.

·

The vehicle is being driven on a rough road or steep hill causing the vehicle speed to fluctuate while the vehicle is coasting.

·

The hybrid vehicle transaxle assembly temperature is excessively low.

(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.)

·

The SPORT drive mode is selected.

·

The driving support system is turned on.

xii.

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.

xiii.

Stop the vehicle, turn the ignition switch off and wait for 1 minute or more.

xiv.

Turn the ignition switch to ON (READY).

xv.

Check that the generator resolver learning incomplete and motor resolver learning incomplete messages are not displayed on the multi-information display.

HINT:

If the ignition switch is turned to ON after less than 1 minute has elapsed since the ignition 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.
