DTC DETECTION LOGIC

CAUTION:

• Never use an extension cable or similar item during charging.

• For charging with AC100 V, use an independent socket with 15 A or higher rating. For charging with

AC200 V, use an independent 20 A or higher socket.

NOTE:

• DTC B2840 may be detected when an extension cable is used when charging using the EVSE.

• DTC B2840 may be detected when an independent socket of 15 A or higher (AC100 V charging), or 20 A or

higher (AC200 V charging), is not used.

than 329 V, continually for 0.2 seconds or more, five or 
more times.

• During normal charging, output voltage inside the PDM 

(Power Delivery Module) is 450 V or more continuously 
for 1 second or more, five or more times, or recovery from 
charge interrupt does not occur for 60 seconds or more 
after output voltage of 450 V or more occurs.

• During normal charging, output voltage inside the PDM 

(Power Delivery Module) is less than 170 V continuously 
for 1 second or more, five or more times, or recovery from 
charge interrupt does not occur for 60 seconds or more 
after output voltage of less than 170 V occurs.

• Harness and connec-

tor

• PDM (Power Delivery 

Module)

B

PDM (POWER DELIV-
ERY MODULE)
(Component internal mal-
function)

• Before the start of normal or quick charging, during quick 

charging, or during driving, AC input voltage for the PDM 
(Power Delivery Module) is 60 V or more continuously for 
10 seconds or more.

• During normal charging, AC input current to the PDM 

(Power Delivery Module) is 32 A or more continuously for 
0.2 seconds or more, 20 or more times, or recovery from 
charge interrupt does not occur for 60 seconds or more 
after input current of 32 A or higher occurs.

• Before the start of normal or quick charging, during quick 

charging, or during driving, output current from the master 
power converter inside the PDM (Power Delivery Module) 
is 5 A or higher continuously for 10 seconds or more.

• An I2C communications malfunction occurs in the PDM 

(Power Delivery Module).

• During normal charging, DC voltage output by the PDM 

(Power Delivery Module) is 440 V or more, or 240 V or 
less, continuously for 5 seconds or more.

• During normal charging, output current from the master 

power converter inside the PDM (Power Delivery Module) 
is 

±20% or more than the command current value contin-

uously for 60 seconds or more. (Models for 6.0 kw)

• During normal charging, output current from the master 

power converter inside the PDM (Power Delivery Module) 
is 

±50% or more than the command current value contin-

uously for 30 seconds or more. (Models for 6.0 kw)

• Before the start of normal or quick charging, during quick 

charging, or during driving, output current from the slave 
power converter inside the PDM (Power Delivery Module) 
is 5 A or higher continuously for 10 seconds or more. 
(Models for 6.0 kw)

• During normal charging, output current from the slave 

power converter inside the PDM (Power Delivery Module) 
is 

±20% or more than the master current value continu-

ously for 60 seconds or more. (Models for 6.0 kw)

• During normal charging, output current from the slave 

power converter inside the PDM (Power Delivery Module) 
is 

±50% or more than the master current value continu-

ously for 30 seconds or more. (Models for 6.0 kw)

(Component or system 
over temperature)

During normal charging, the temperature of the circuits in-
side the PDM (Power Delivery Module) are excessively high 
continuously for 30 seconds or more.

DANGER:

Since hybrid vehicles and electric vehicles contain a high voltage battery, there is the risk of

electric shock, electric leakage, or similar accidents if the high voltage component and vehicle are

handled incorrectly. Be sure to follow the correct work procedures when performing inspection and

maintenance.

WARNING:

• Be sure to remove the service plug in order to disconnect the high voltage circuits before perform-

ing inspection or maintenance of high voltage system harnesses and parts.

• The removed service plug must always be carried in a pocket of the responsible worker or placed in

the tool box during the procedure to prevent the plug from being connected by mistake.

• Be sure to wear insulating protective equipment consisting of glove, shoes, face shield and glasses

before beginning work on the high voltage system.

• Never allow workers other than the responsible person to touch the vehicle containing high voltage

parts. To keep others from touching the high voltage parts, these parts must be covered with an insu-

lating sheet except when using them.

• Refer to 

VC-6, "High Voltage Precautions"

.

CAUTION:

Never bring the vehicle into the READY status with the service plug removed unless otherwise

instructed in the Service Manual. A malfunction may occur if this is not observed.

1.

CHECK PDM (POWER DELIVERY MODULE) HIGH-VOLTAGE HARNESS CONNECTION

1. Turn power switch OFF.

2. Remove PDM (Power Delivery Module) from the vehicle. Refer to 

VC-112, "Removal and Installation"

.

3. Check the connection of each high-voltage harness on the PDM (Power Delivery Module) side for loose-

ness and damage.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts.

2.

CHECK PDM (POWER DELIVERY MODULE) HIGH-VOLTAGE HARNESS

1. Remove each high-voltage harness from PDM (Power Delivery Module). Refer to 

VC-119, "Disassembly

and Assembly"

.

2. Check the continuity of the following high-voltage harness.
