B2098 IGNITION RELAY ON STUCK

Description

INFOID:0000000003131999

• 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 unified meter and A/C
amp.(Emergency 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.

1.

CHECK FUSES AND FUSIBLE LINK

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

Is the fuse fusing?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit if a fuse or fusible link is

blown.

NO

>> GO TO 2.

2.

CHECK POWER SUPPLY CIRCUIT

1.

Turn ignition switch OFF.

2.

Disconnect IPDM E/R connector.

3.

Check voltage between IPDM E/R harness connector and ground.

Is the measurement value normal?
