INTELLIGENT KEY INTERLOCK STORIN G : Special Repair RequirementINFOID:0000000006248333
Intelligent Key Interlock Storage Procedure
Performing the following operation associates the regist ered driving position with Intelligent Key. When driver
door unlock operation is performed by Intelligent Key or driver door request switch, display of the registered
driving position and turnout operation can be performed.
1.STEP 1
Check the following conditions.
 Ignition switch: OFF
 Initialization: done
 Driving position: registered
>> GO TO 2.
2.STEP 2
1. Push set switch. NOTE:
Memory indicator for which driver seat position is already retained in memory is illuminated for 5 seconds.
2. Push the Intelligent Key unlock button within 5 seconds after pushing memory switch (while the memory indicator is turned ON).
NOTE:
From the time registration is performed, the app licable memory indicator blinks for 5 seconds.
>> GO TO 3.
3.STEP 3
Confirm the operation of each part with memory operation and Intelligent Key interlock operation.

B2128 UART COMMUNICATION LINE
B2128 UART COMMUNICATION LINE
DescriptionINFOID:0000000006248348
Driver seat control unit performs UART communication with the automatic drive positioner control unit using 1
communication lines. Driver seat control unit receives t he operation signals of tilt & telescopic switch, door mir-
ror remote control switch, and the position signals of door mirror sensor from the automatic drive positioner
control unit and transmits the operation request signal.

DTC CONFIRMATION PROCEDURE
1.STEP 1
Turn ignition switch ON.
>> GO TO 2.
2.PROCEDURE
Check “Self diagnostic result” with CONSULT-III.
Is the DTC detected?
YES >> Perform diagnosis procedure. Refer to ADP-64, "DiagnosisProcedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000006248350
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON.
2. Check “Self diagnostic result” with CONSULT-III.
3. Erase the DTC.
4. Perform DTC confirmation procedure. Refer to ADP-62, "
DTC Logic".
Is the DTC displayed again?
YES >> GO TO 2.
NO >> Check intermittent incident. Refer to GI-40, "
Intermittent Incident".
