• 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.

Diagnosis Procedure

INFOID:0000000010741726

1.

CHECK FUSIBLE LINK

Check that the following IPDM E/R fusible links are not blown.

With QR engine models

Except for QR engine models

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.
