MEMORY STORING
MEMORY STORING : DescriptionINFOID:0000000006248330
Always perform the memory storage when the battery terminal is disconnected or the driver seat control unit is
replaced. The memory function will not operate normally if no memory storage is performed.
MEMORY STORING : Special Repair RequirementINFOID:0000000006248331
Memory Storage Procedure
Two positions for the driver seat, steering column and outside mirror can be stored for memory operation by
following procedure.
1.STEP 1
Check the following conditions.
 Ignirion switch: ON
 A/T shift selector: P position
>> GO TO 2.
2.STEP 2
Adjust driver seat, steering colu mn and outside mirror position manually.
>> GO TO 3.
3.STEP 3
1. Push set switch. NOTE:
 Memory indicator for which driver seat position is already retained in memory is illuminated for 5 sec-
onds.
 Memory indicator for which driver seat position is not retained in memory is illuminated for 0.5 second.
2. Push the memory switch (1 or 2) for at least 1 second within 5 seconds after pushing the set switch.
NOTE:
 To enter driver seat positions into blank memo ry, memory indicator will be turned on for 5 seconds.
 To modify driver seat positions, memory indicato r will be turned OFF for 0.5 second, then turned ON for
5 seconds.
NOTE:
If memory is stored in the same memory switch, the previous memory will be deleted.
>> GO TO 4.
4.STEP 4
Confirm the operation of each part with memory operation.

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.
