B20DD IGNITION RELAY ON CIRCUIT
B20DD IGNITION RELAY ON CIRCUIT
DTC Description
INFOID:0000000010499197
• 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:0000000010499198
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. 56 (15 A)] at the downstream of IGN 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. 56 (15 A)] at the downstream of IGN
relay in IPDM E/R.
NO
>> GO TO 2.
2.
CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 2
1.
Return fuse [No. 56 (15 A)] downstream of IGN relay in IPDM E/R back to the original position.
2.
Remove fuse [No. 61 (20 A)] at the downstream of IGN relay in IPDM E/R, and check the change in “Self-
diagnosis Result”.
Is it now a past malfunction?
DTC No.

YES
>> Perform an inspection of the downstream circuit of fuse [No. 63 (10 A)] at the downstream of IGN
relay in IPDM E/R.
NO
>> GO TO 4.
4.
CHECK IGNITION RELAY POWER SUPPLY CIRCUIT 4
1.
Return fuse [No. 63 (10 A)] downstream of IGN relay in IPDM E/R back to the original position
2.
Remove fuse [No. 67 (10 A)] at the downstream of IGN 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. 67 (10 A)] at the downstream of IGN
relay in IPDM E/R.
NO
>> GO TO 5.
5.
REPLACE IPDM E/R
1.
Replace IPDM E/R. Refer to
PCS-68, "Removal and Installation"
.
2.
Perform DTC confirmation procedure. Refer to
.
Is DTC detected?
YES

Diagnosis Procedure
INFOID:0000000010499201
1.
CHECK FUSIBLE LINK
Check that the following IPDM E/R fusible links are not blown.
Is the fuse fusing?
YES
>> Replace the blown fusible link after repairing the affected circuit if a fusible link is blown.
NO
>> GO TO 2.
2.
CHECK POWER SUPPLY CIRCUIT
1.
Turn the ignition switch OFF.
2.
Disconnect IPDM E/R connector.
3.
Check voltage between IPDM E/R harness connector and the ground.
Is the measurement value normal?
YES
>> GO TO 3.
NO
>> Repair the harness or connector.
3.
CHECK GROUND CIRCUIT
Check continuity between IPDM E/R harness connectors and the ground.
Does continuity exist?
YES
>> INSPECTION END
NO
>> Repair the harness or connector.
Signal name
Fusible link No.
