BEFORE REPLACEMENT
When replacing CAN gateway, save or print current v ehicle specification with CONSULT-III configuration
before replacement.
NOTE:
If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after
replacing CAN gateway.
AFTER REPLACEMENT
CAUTION:
 When replacing CAN gateway, you must perfo rm “WRITE CONFIGURATION” with CONSULT-III.
 Complete the procedure of “WRITE CONFIGURATION” in order.
 If you set incorrect “WRITE CONF IGURATION”, incidents might occur.
 Configuration is different for each vehicle mode l. Confirm configuration of each vehicle model.
 Never perform “WRITE CONFIGURATION” except for new CAN gateway.
Work ProcedureINFOID:0000000006220582
1.SAVING VEHICLE SPECIFICATION
CONSULT-III Configuration
Perform “READ CONFIGURATION” to save or prin t current vehicle specification. Refer to L A N - 111 , "
Descrip-
tion".
NOTE:
If “READ CONFIGURATION” can not be used, use the “WRITE CONFIGURATION - Manual selection” after
replacing CAN gateway.
>> GO TO 2.
2.REPLACE CAN GATEWAY
Replace CAN gateway. Refer to LAN-117, "
Removal and Installation".
>> GO TO 3.
3.WRITING VEHICLE SPECIFICATION

way.
Configuration has three functions as follows
CAUTION:
 When replacing CAN gateway, you must perfo rm “WRITE CONFIGURATION” with CONSULT-III.
 Complete the procedure of “WRITE CONFIGURATION” in order.
 If you set incorrect “WRITE CONF IGURATION”, incidents might occur.
 Configuration is different for each vehicle model. Confirm conf iguration of each vehicle model.
 Never perform “WRITE CONFIGURATION” except for new CAN gateway.
Work ProcedureINFOID:0000000006220584
1.WRITING MODE SELECTION
CONSULT-III Configuration
Select “CONFIGURATION” of CAN gateway.
When writing saved data>>GO TO 2.
When writing manually>>GO TO 3.
2.PERFORM “WRITE CONFIG URATION - CONFIG FILE”
CONSULT-III Configuration
Perform “WRITE CONFIGURATION - Config file”.
>> WORK END
3.PERFORM “WRITE CONFIGURATION - MANUAL SELECTION”
CONSULT-III Configuration
1. Select “WRITE CONFIGURATION - Manual selection”.
2. Select “SETTING”.
3. When “COMMAND FINISHED”, select “End”.
>> GO TO 4.
4.CHECK “SELF DIAGNOSTIC RESULT”
1. Erase all ECU self-diagnosis results using CONSULT-III.
2. Turn the ignition switch OFF.
3. Turn the ignition switch ON and wait for 2 seconds or more.
4. Perform “All DTC Reading” using CONSULT-III.
5. Check that all ECU self-diagnosis results have no DTC of CAN communication. NOTE:
DTCs of CAN communication are as follows:
 U0101
 U0140
 U0164
 U1000
 U1001
 U1507
Function Description
READ CONFIGURATION  Reads the vehicle configuration of current CAN gateway.
 Saves the read vehicle configuration.
WRITE CONFIGURATION - Manual selection Writes the vehicle configuration with manual selection.
WRITE CONFIGURATION - Config file Writes the vehicle configuration with saved data.
