U1000 CAN COMM CIRCUIT
Description
INFOID:0000000007542281
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
Description
INFOID:0000000007542284
• 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.

Diagnosis Procedure
INFOID:0000000007542290
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.
