B2099 IGNITION RELAY OFF STUCK

Description

INFOID:0000000009652864

• 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.
NOTE:
The ignition relay does not turn ON for 3 seconds after emergency OFF even if the push-button ignition switch
is pressed.

DTC DETECTION LOGIC

NOTE:

When IPDM E/R power supply voltage is low (Approx. 7 - 8 V for about 1 second), the “DTC: B2099” may be detected.

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON.

2.

Turn ignition switch OFF and wait 1 second or more.

3.

Check DTC in “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.

Is DTC detected?

YES

>> Refer to 

PCS-33, "Diagnosis Procedure"

.

NO

>> INSPECTION END.

Diagnosis Procedure

INFOID:0000000009652866

1.

CHECK FUSE

Check that all of the fuses installed on the downstream of the contact point side circuit of the ignition relay in
IPDM E/R are not blown.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Replace the blown fuse after replacing the affected circuit if a fuse is blown.

2.

CHECK IGNITION RELAY CONTROL CIRCUIT VOLTAGE

1.

Turn ignition switch ON

2.

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

Is the inspection result normal?

YES

>> Replace IPDM E/R. Refer to 

PCS-36, "Removal and Installation"

.

NO

>> GO TO 3.

CHECK BATTERY VOLTAGE

Check battery voltage.
Which is the measurement result?

More than 12.4 V>>GO TO 4.
Less than 12.4 V>>Perform battery inspection. Refer to 

PG-97, "How to Handle Battery"

Diagnosis Procedure

INFOID:0000000009652867

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 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.
