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.
