AUTOMATIC DRIVE POSITIONER
Revision: 2004 November 2004 FX35/FX45
KEY FOB INTERLOCK OPERATION

Perform memory operation, exiting operation and entry operation by pressing key fob unlock button.
NOTE:

If steering wheel operation is cancelled, the system performs seat and mirror operation only.

If Entry/Exiting operation is cancelled, the system performs steering wheel operation and mirror operation
only.

If ignition switch turns ON in the middle of memory operation, the system does not perform exiting opera-
tion after memory operation.

If ignition switch turns ON in the middle of exiting operation, entry operation starts at that time.
FAIL - SAFE MO DE
When any manual and automatic operations are not performed, if any motor operations of seats or tilt of steer-
ing are detected for approx. 0.1 sec or more, status is judged “Output malfunction”. Motor operation will be
suspended automatically, and all automatic operations will be ineffective (in this case, the motor will not oper-
ate manually).
CANCEL OF FAIL-SAFE MODE

The mode is cancelled when the selector lever is shifted to P position from any other position.

Can Communication Inspection Using CONSULT-II (Self-diagnosis)AIS002XL
1. SELF-DIAGNOSTIC RESULT CHECK
CAUTION:
If CONSULT-II is used with no connection of CONSULT-II CONVERTER, malfunctions might be
detected in self-diagnosis depending on control unit which carry out CAN communication.
1. Connect to CONSULT-II, and select “AUTO DRIVE POS.” on the “SELECT DAIAG SYSTEM” screen.
2. Select “SELF-DIAG RESULTS” on “SELECT DISG MODE” screen.
3. Check display content in self-diagnostic results.
Displayed U1000?
