B20DD IGNITION RELAY ON CIRCUIT
DTC Description
INFOID:0000000010741722
• IPDM E/R operates the ignition relay when it receives an ignition switch ON signal from BCM via CAN com-
munication.
• Turn the ignition relay OFF by pressing the push-button ignition switch once when the vehicle speed is 4 km/
h (2.5 MPH) or less.
• Turn the ignition relay OFF with the following operation when the vehicle speed is more than 4 km/h (2.5
MPH) or when an abnormal condition occurs in CAN communication from the combination meter (Emer-
gency OFF)
- Press and hold the push-button ignition switch for 2 seconds or more.
- Press the push-button ignition switch 3 times within 1.5 seconds.
NOTE:
The ignition relay does not turn ON for 3 seconds after emergency OFF even if the push-button ignition switch
is pressed.

Diagnosis Procedure
INFOID:0000000010741723
1.
CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 1
1.
Turn ignition switch ON
2.
Display “Self-diagnosis Result” of IPDM E/R with CONSULT.
3.
Remove fuse [No. 91 (20 A)] at the downstream of ignition relay in IPDM E/R, and check the change in
“Self-diagnosis Result”.
Is it now a past malfunction?
YES
>> Perform an inspection of the downstream circuit of fuse [No. 91 (20 A)] at the downstream of igni-
tion relay in IPDM E/R.
NO
>> GO TO 2.
2.
CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 2
1.
Return fuse [No. 91 (20 A)] downstream of ignition relay in IPDM E/R back to the original position.
2.
Remove fuse [No. 95 (5 A)] at the downstream of ignition relay in IPDM E/R, and check the change in
“Self-diagnosis Result”.
Is it now a past malfunction?
DTC No.
