• 1-39: Displayed if any previous malfunction is present when current condition is normal. The numeral value increases by one at each

IGN ON to OFF cycle from 1 to 39. The counter remains at 39 even if the number of cycles exceeds it. However, the counter is reset
to 1 if any malfunction is detected again, the normal operation is resumed and the ignition switch is turned from OFF to ON.

MEMORY STORING

Description

INFOID:0000000008463562

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.

Work Procedure

INFOID:0000000008463563

Two positions for the driver seat, steering column, and outside mirror can be stored for memory operation by
following procedure.
NOTE:
If memory is stored in the same memory switch, the previous memory will be deleted.

1.

STEP 1

Check the following conditions.
• Ignition switch: ON
• CVT shift selector: P position

>> GO TO 2.

2.

STEP 2

1.

Adjust driver seat and outside mirror position manually.

2.

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.

3.

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 memory, memory indicator will be turned on for 5 seconds.
• To modify driver seat positions, memory indicator will be turned OFF for 0.5 second, then turned ON for

5 seconds.

4.

Confirm the operation of each part with memory operation.

U1000 CAN COMM CIRCUIT

Description

INFOID:0000000008463566

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.
