ACCELERATOR PEDAL RELEASED POSITION LEARNING

Description

INFOID:0000000010120593

Accelerator Pedal Closed Position Learning is a function of VCM to learn the fully released position of the

accelerator pedal by monitoring the accelerator pedal position sensor output signal. This work must be per-

formed each time the harness connector of the accelerator pedal position sensor or VCM harness connector is

disconnected.

Work Procedure

INFOID:0000000010120594

1.

START

1. Check that accelerator pedal is fully released.

2. Turn power switch ON.and wait at least 2 seconds.

3. Turn power switch OFF and wait at least 90 seconds.

CAUTION:

During this period, never perform vehicle handling such as opening and closing of doors. If some

kind of vehicle handling is performed, then wait another 90 seconds or more from the time of the

vehicle handling.

4. Repeat steps 2 and 3 for 4 times.

5. Turn power switch OFF and wait at least 90 seconds.

CAUTION:

During this period, never perform vehicle handling such as opening and closing of doors. If some

kind of vehicle handling is performed, then wait another 90 seconds or more from the time of the

vehicle handling.

LI-ION BATTERY GRADUAL CAPACITY LOSS DATA CLEAR

LI-ION BATTERY GRADUAL CAPACITY LOSS DATA CLEAR

Description

INFOID:0000000010120595

Perform Li-ion Battery Gradual Capacity Loss Data Clear when the Li-ion battery or Li-ion battery controller is

replaced with a new one. VCM saves the Li-ion battery deterioration information sent from the Li-ion battery

controller and manages the Li-ion battery replacement timing. When the Li-ion battery or Li-ion battery control-

ler is replaced with a new one, there is a difference between the Li-ion battery deterioration data stored in

VCM and the actual Li-ion battery deterioration level. In this case, VCM will incorrectly manage the Li-ion bat-

tery replacement timing. So perform Li-ion Battery Deterioration Data Clear to clear the Li-ion battery deterio-

ration data stored in VCM.

CAUTION:

Never perform Li-ion Battery Deterioration Data Clear when the Li-ion battery or Li-ion battery control-

ler is not replaced as new one.

Work Procedure

INFOID:0000000010120596

1.

LI-ION BATTERY GRADUAL CAPACITY LOSS DATA CLEAR

 With CONSULT

1. Turn power switch ON.

2. On the CONSULT screen, select “EV/HEV” >> “WORK SUPPORT” >> “BATTERY GRADUAL CAP LOSS

DATA CLEAR”.

3. Touch “START” and wait a few seconds.

4. Make sure that “COMPLETE” is displayed on CONSULT screen.

LI-ION BATTERY JUNCTION BOX DATA CLEAR

Description

INFOID:0000000010120597

Perform Li-ion Battery Junction Box Data Clear when the Li-ion Battery Junction Box is replaced with a new

one. VCM counts the times system main relay is turned off due to a large current and use this information to

manage the system main relay deterioration status. As the system main relay deterioration status progresses,

a DTC “P31DE” is detected and notification that the Li-ion battery junction box needs to be replaced is given.

When the Li-ion Battery Junction Box is replaced with a new one, there is a difference between the System

Main Relay cutoff count stored in VCM and the actual System Main Relay cutoff count. In this case, VCM will

detect the DTC with incorrect timing. So perform Li-ion Battery Junction Box Data Clear to clear the System

Main Relay cutoff count stored in VCM.

Work Procedure

INFOID:0000000010120598

1.

LI-ION BATTERY JUNCTION BOX DATA CLEAR

 With CONSULT

1. Turn power switch ON.

2. On the CONSULT screen, select “EV/HEV” >> “WORK SUPPORT” >> “LI-ION BATTERY JUNCTION

BOX DATA CLEAR”.

3. Touch “START” and wait a few seconds.

4. Make sure that “COMPLETE” is displayed on CONSULT screen.
