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.

YES

>> Refer to 

PCS-64, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

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.

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.
