BEFORE REPLACEMENT
When replacing A/C auto amp., save or print current v ehicle specification with CONSULT configuration before
replacement.
NOTE:
If “Before Replace ECU” cannot be used, use the “After Replace ECU” or “Manual Configuration” after replac-
ing A/C auto amp.
AFTER REPLACEMENT
CAUTION:
• When replacing A/C auto amp., you must perform “After Replace ECU” with CONSULT.
- Complete the procedure of “After Replace ECU” in order.
- If you set incorrect “After Replace ECU”, incidents might occur.
- Configuration is different for each vehicle mode l. Confirm configuration of each vehicle model.
Work ProcedureINFOID:0000000009463117
1.SAVING VEHICLE SPECIFICATION
CONSULT
Enter "Re/Programming, Configuration" and perform “Before Replace ECU” to save or print current vehicle
specification.
NOTE:
If “Before Replace ECU” cannot be used, use the "After Replace ECU" or "Manual Configuration" after replac-
ing A/C auto amp.
>> GO TO 2.
2.REPLACE A/C AUTO AMP.
Replace A/C auto amp. Refer to HAC-102, "Removal and Installation"
.
>> GO TO 3.
3.WRITING VEHICLE SPECIFICATION
CONSULT
1. Enter "Re/Programming, Configuration".
2. If “Before Replace ECU” operation was performed, automatically an "Operation Log Selection" screen will
be displayed. Select the applicable file from the "S aved Data List" and press “Confirm” to write vehicle
specification. Refer to HAC-53, "Work Procedure"
.
3. If “Before Replace ECU” operation was not performed, select "After Replace ECU" or "Manual Configura-
tion" to write vehicle specification. Refer to HAC-53, "Work Procedure"
.
>> GO TO 4.
4.OPERATION CHECK
Check that the operation of the A/C auto amp. is normal.
>> Work End.

Vehicle specification needs to be written with CONSULT because it is not written after replacing A/C auto amp.
Configuration has three functions as follows:
CAUTION:
• When replacing A/C auto amp., you must perform “Select Saved Data List” or "After Replace ECU"
with CONSULT.
• Complete the procedure of “Select Saved Da ta List” or "After Replace ECU" in order.
• If you set incorrect “Select Saved Data List” or "After Replace ECU", incidents might occur.
• Configuration is different for each vehicle model. Confirm conf iguration of each vehicle model.
• Never perform “Select Saved Data List” or "A fter Replace ECU" except for new A/C auto amp.
Work ProcedureINFOID:0000000009463119
1.WRITING MODE SELECTION
CONSULT
Select “Reprogramming, Configuration” of A/C auto amp.
When writing saved data>>GO TO 2.
When writing manually>>GO TO 3.
2.PERFORM “SAVED DATA LIST”
CONSULT
Automatically “Operation Log Selection” window will disp lay if “Before Replace ECU” was performed. Select
applicable file from the “Saved Data List” and press “Confirm”.
>> Work End.
3.PERFORM “AFTER REPLACE ECU” OR “MANUAL CONFIGURATION”
CONSULT
1. Select “After Replace ECU” or “Manual Configuration”.
2. Identify the correct model and configuration list. Refer to HAC-54, "Configuration List"
.
3. Confirm and/or change setting value for each item.
CAUTION:
Thoroughly read and understand the vehicle speci fication. ECU control may not operate normally
if the setting is not correct.
4. Select “Next”. CAUTION:
Make sure to select “Next”, confirm each setting value and press “OK” even if the indicated con-
figuration of brand new A/C auto am p. is same as the desirable configuration. If not, configuration
which is set automatically by selecti ng vehicle model cannot be memorized.
5. When "Completed", select "End".
>> GO TO 4.
4.OPERATION CHECK
Confirm that each function controlled by A/C auto amp. operates normally.
Function Description
"Before Replace ECU" • Reads the vehicle configuration of current A/C auto amp.
• Saves the read vehicle configuration.
"After Replace ECU" Writes the vehicle configuration with manual selection.
"Select Saved Data List" Writes the vehicle configuration with saved data.

U1000 CAN COMM CIRCUIT
DescriptionINFOID:0000000009463121
CAN (Controller Area Network) is a serial communication system for real time application. It is an on-vehicle
multiplex communication system with high data communication speed and excellent error detection ability.
Many electronic control units are equipped onto vehicl es, and each control unit shares information and links
with other control units during operation (not independent ). In CAN communication, control units are con-
nected with two 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. Refer to
LAN-32, "CAN COMMUNICATION SYSTEM : CAN Communication Signal Chart"
.
