B2099 IGNITION RELAY OFF STUCK
B2099 IGNITION RELAY OFF STUCK
Description
INFOID:0000000009945003
• 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.

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.
DTC CONFIRMATION PROCEDURE
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
.
NO
>> INSPECTION END.
Diagnosis Procedure
INFOID:0000000009945005
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?

Diagnosis Procedure
INFOID:0000000009945006
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.
