SEAT MEMORY INDICATOR LAMP
SEAT MEMORY INDICATOR LAMP
DescriptionINFOID:0000000005147572
• The seat memory switch is installed on the driver side door trim. The operation signal is inputted to the auto-
matic drive positioner control unit when the memory switch is operated.
• The status of automatic drive positioner system can be checked according to the illuminating/flashing status.
Component Function CheckINFOID:0000000005147573
1. CHECK FUNCTION
1. Select “MEMORY SW INDCTR” in “A ctive test” mode with CONSULT-III.
2. Check the memory indicator operation.
Is the operation of relevant parts normal?
YES >> Inspection End.
NO >> Perform diagnosis procedure. Refer to ADP-112, "
DiagnosisProcedure".
Diagnosis ProcedureINFOID:0000000005147574
Regarding Wiring Diagram information, refer to ADP-138, "Wiring Diagram".
1. CHECK SEAT MEMORY INDICATOR CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect automatic drive positioner control unit and seat memory switch.

NOTE:
The front seat LH position and pedal adjustment functions (see the following table) operate simultaneously in
the order of priority.
*: In conjunction with sliding the seat, the door mirrors are positioned.
CANCEL OF FAIL-SAFE MODE
The mode is cancelled when the A/T selector lever is shifted to P position from any other position.
DTC IndexINFOID:0000000005147579
*1:
• 0: Current malfunction is present
• 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 re set
to 1 if any malfunction is detected again, the normal operation is resumed and the ignition switch is turned from OFF to ON. OPERATED PORTION
