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

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 

PCS-32, "Diagnosis Procedure"

.

NO

>> INSPECTION END.

Diagnosis Procedure

INFOID:0000000012197169

1.

CHECK SELF DIAGNOSTIC RESULT

Check DTC using CONSULT.
What is the display history of DTC “B2098”?

“CRNT”>> GO TO 2.

“PAST” >> GO TO 5.

2.

CHECK IGNITION RELAY CONTROL CIRCUIT VOLTAGE 1

1. Turn ignition switch ON

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

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

CHECK IGNITION RELAY CONTROL CIRCUIT VOLTAGE 2

1. Disconnect IPDM E/R connector.

2. Turn ignition switch ON

.

NO

>> Check the harness of the ignition relay control circuit for a short to power.

4.

CHECK IGNITION RELAY CONTROL CIRCUIT

1. Disconnect IPDM E/R connector.

2. Check continuity between IPDM E/R harness connector and ground.

Is the inspection result normal?

YES

>> Perform the diagnosis procedure for DTC B26F2. Refer to

Description

INFOID:0000000012197170

• 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/

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 

PCS-34, "Diagnosis Procedure"

.

NO

>> INSPECTION END.

Diagnosis Procedure

INFOID:0000000012197172

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-37, "Removal and Installation"

.

NO

>> GO TO 3.
