B2098 IGNITION RELAY ON STUCK
B2098 IGNITION RELAY ON STUCK
Description
INFOID:0000000012197167
• 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.
1.
PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON.
2. Check DTC in “Self Diagnostic Result” mode of “IPDM E/R” using CONSULT.
Is DTC detected?
YES
>> Refer to
