ADDITIONAL SERVICE WHEN REPLACING IPDM E/R
Description
INFOID:0000000010499180
After replaced IPDM E/R, it is necessary to perform control unit configuration and height sensor initialize (For
LED headlamp models) with CONSULT.
BEFORE REPLACEMENT
When replacing IPDM E/R, save or print current vehicle specification with CONSULT configuration before
replacement.
NOTE:
If “Before Replace ECU” of “Read/Write Configuration” cannot be used, use the “Manual Configuration” after
replacing IPDM E/R.
AFTER REPLACEMENT
CAUTION:
• When replacing IPDM E/R, always perform “Read/Write Configuration” or “Manual Configuration”
with CONSULT. Or not doing so, IPDM E/R control function does not operate normally.
• Never perform “Read / Write Configuration” or “Manual Configuration” except for new IPDM E/R or
the control function may not operate normally.
Work Procedure
INFOID:0000000010499181
1.
SAVING VEHICLE SPECIFICATION (IPDM E/R)
CONSULT Configuration
Perform “Before Replace ECU” of “Read / Write Configuration” to save or print current vehicle specification.
Refer to
.
NOTE:
If “Before Replace ECU” of “Read/Write Configuration” cannot be used, use the “Manual Configuration” after
replacing IPDM E/R.

CONFIGURATION (IPDM E/R)
Description
INFOID:0000000010499182
There is no vehicle specification in new IPDM E/R, so the vehicle specification needs to be written in IPDM E/
R with CONSULT.
Configuration has three functions as follows.
CAUTION:
• When replacing IPDM E/R, always perform “Read/Write Configuration” or “Manual Configuration”
with CONSULT. Or not doing so, IPDM E/R control function does not operate normally.
• Never perform “Read / Write Configuration” or “Manual Configuration” except for new IPDM E/R or
the control function may not operate normally.
Work Procedure
INFOID:0000000010499183
1.
WRITING MODE SELECTION
CONSULT Configuration
Select “CONFIGURATION” of IPDM E/R.
When writing saved data>>GO TO 2.
When writing manually>>GO TO 3.
2.
PERFORM “WRITE CONFIGURATION”
CONSULT Configuration
1.
Select “READ/WRITE CONFIGURATION”.
2.
Select “After Replace ECU”.
>> GO TO 4.
3.
PERFORM “MANUAL CONFIGURATION”
CONSULT Configuration
1.
Select “MANUAL CONFIGURATION”.
2.
Identify the correct model and configuration list. Refer to
CAUTION:
• Thoroughly read and understand the vehicle specification. ECU control may not operate nor-
mally if the setting is not correct.
• Make sure to select “SETTING” even if the indicated configuration of brand new IPDM E/R is
same as the desirable configuration. If not, configuration which is set automatically by selecting
vehicle model cannot be memorized
3.
Sets the displayed item and then select “NEXT”.
NOTE:
If item is not displayed, select “NEXT”.
4.
Check that the configuration has been successfully written and touch “End”.
>> GO TO 4.
4.
OPERATION CHECK
Confirm that each function controlled by IPDM E/R operates normally.
>> WORK END

U1000 CAN COMM CIRCUIT
DTC Description
INFOID:0000000010499193
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.
DTC DETECTION LOGIC
POSSIBLE CAUSE
CAN communication system
FAIL-SAFE
When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN
communication recovers normally, it also returns to normal control.
If No CAN Communication Is Available With ECM
If No CAN Communication Is Available With BCM
DTC CONFIRMATION PROCEDURE
1.
PERFORM DTC CONFIRMATION PROCEDURE
1.
Turn the ignition switch OFF.
2.
Turn the ignition switch ON and wait for 2 seconds or more.

• 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
