DTC/CIRCUIT DIAGNOSIS

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000009944997

CAN (Controller Area Network) is a serial communication line for real time applications. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Modern
vehicle is equipped with many electronic control unit, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

B2098 IGNITION RELAY ON STUCK

B2098 IGNITION RELAY ON STUCK

Description

INFOID:0000000009945000

• 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.

>> Refer to 

PCS-16, "Diagnosis Procedure"

.

NO

>> INSPECTION END.

Diagnosis Procedure

INFOID:0000000009945002

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
