With CONSULT
1. Turn power switch ON.
2. Erase DTC.
3. Turn power switch OFF.
4. Perform DTC confirmation procedure again by using a EVSE other than the one is used for the previous
DTC confirmation procedure. Refer to
Is the DTC detected again?
YES
>> Check the intermittent incident. Refer to
GI-53, "Intermittent Incident"

(Malfunction type)
DTC detection condition
Possible causes
B29C1
A
EVSE
(No signal)
• During normal charging, although the AC
power source is being input, there is a break
of the PWM communication signal from
EVSE.
• Before normal charging or during normal
charging, there is a peak value malfunction
in the PWM communication signal from
EVSE.
• Harness and connector
(Normal charge port circuit is
open or shorted.)
• Normal charge port
• EVSE
• PDM (Power Delivery Module)
B
EVSE
(Signal stuck low)
Before the start of normal charging or during
normal charging, there is no AC power source
input even though the PDM (Power Delivery
Module) permits the start of charging.
C
EVSE
(Unexpected operation)
Before the start of normal charging, there is
AC power source input despite the fact that
PWM communication is not received from
EVSE.
• Harness and connector
(Normal charge port circuit is
open or shorted.)
• EVSE
• PDM (Power Delivery Module)
D
EVSE
(Signal stuck high)
After charging is completed, AC power source
continues to be input even though the PDM
(Power Delivery Module) charging is stopped.
E
EVSE
(Signal invalid)
When an error is detected in a PWM commu-
nication signal from EVSE during normal
charge.
• Harness and connector
(Normal charge port circuit is
open or shorted.)
• Normal charge port
• EVSE
• PDM (Power Delivery Module)
Malfunction type
Time
A
No signal
1 minute or more
B

PERFORM DTC CONFIRMATION PROCEDURE OF TYPE D
With CONSULT
1. Perform normal charging until charging is completed.
2. Turn power switch ON.
3. Check “Self-diagnosis result” of “CHARGER/PD MODULE”.
Is DTC detected?
YES
>> Proceed to
VC-98, "TYPE C AND D : Diagnosis Procedure"
NO
>> INSPECTION END
TYPE A, B AND E
TYPE A, B AND E : Diagnosis Procedure
INFOID:0000000010121286
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.

4.
CHECK NORMAL CHARGE PORT
Check the normal charge port. Refer to
.
Is the inspection result normal?
YES
>> GO TO 5.
NO
>> Replace normal charge port. Refer to
VC-135, "Removal and Installation"
5.
CHECK EVSE COMMUNICATION
1. Disconnect PDM (Power Delivery Module) harness connector .
NOTE:
Loosen the PDM (Power Delivery Module) harness connector by
rotating it counterclockwise and remove it.
2. Check the continuity between PDM (Power Delivery Module)
harness connector and normal charge port harness connector.
Is the inspection result normal?
YES
>> GO TO 6.
NO
>> Repair or replace error-detected parts.
6.
CHECK HIGH-VOLTAGE HARNESS
1. Remove normal charge port from PDM (Power Delivery Module). Refer to
VC-112, "Removal and Installa-
2. Check the high-voltage harness continuity between the normal port and PDM (Power Delivery Module).
Is the inspection result normal?
YES
>> Replace PDM (Power Delivery Module) (Fuse is fusing). Refer to
VC-112, "Removal and Installa-
.
NO
>> Repair or replace error-detected parts.

1.
CHECK EVSE SPECIFICATIONS
Check whether or not the EVSE conforms to the SAE-J1772 standard.
Is the correct EVSE being used?
YES
>> GO TO 2
NO
>> Explain to the customer that the correct EVSE must be used.
