Trouble Diagnosis ProcedureEIS008R9
1. Check the trouble symptom and customer's requests.
2. Understand outline of system. Refer to BL-45, "
System Description" .
3. Confirm system operation.
4. Perform self-diagnosis procedures. Refer to BL-113, "
Self-Diagnosis Procedures" .
5. Refer to diagnosis chart by symptom, repair or replace any malfunctioning parts. Refer to BL-114, "
Diag-
nosis Chart" .
6. Inspection End.
Self-Diagnosis ProceduresEIS008RA
INPUT SIGNAL CHECK MODE
Input signal check mode allows testing of switch input signal to the back door control unit.
To activate input signal check mode on the automatic back door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T selector lever in P position.
4. Using the inside emergency release lever, open the back door.
5. Have an assistant press and hold the back door handle switch.
6. While the assistant continues to hold the back door handle switch, turn ignition switch ON (DO NOT start
engine).
7. After approximately 5 seconds, the back door warning chime will sound for 0.5 seconds.
8. Release the back door handle switch.
9. Within 8 seconds of the back door warning chime sounding, press and hold the power liftgate switch.
10. After approximately 5 seconds, the back door warning chime will sound for 1 second.
11. Release the power liftgate switch.
12. The input signal check mode is now initialized.
The input signal check mode can test the following inputs. The back door warning chime will sound for approx-
imately 0.5 seconds each time a switch signal input occurs. Use this test when one of these inputs is not
responding during normal automatic back door operation.
*Back door warning chime should sound as soon as vehicle moves.
Turn ignition switch OFF to end input signal check mode.
OPERATING CHECK MODE
Operating check mode allows self-diagnosis of the automatic back door system.
To activate operating check mode on the automatic back door, perform the following steps:
1. Turn ignition switch OFF.
2. Turn back door close switch to CANCEL (system cancelled).
3. Place A/T selector lever in P position.

ILLUMINATION OPERATION BY LIGHTING SWITCH
With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives
input signal requesting the illumination lamps to illuminate. This input signal is communicated to the IPDM E/R
across the CAN communication lines. The CPU of the IPDM E/R controls the tail lamp relay coil, which, when
energized, directs power

AUTOMATIC DRIVE POSITIONER
Revision: October 20052005 QX56
Manual OperationEIS004XC
The driving position [seat position, steering wheel, pedal position (accelerator, brake) and door mirror position]
can be adjusted with the power seat switch LH, pedal adjusting switch, door mirror remote control switch or
ADP steering switch.
NOTE:

The door mirrors can be manually operated with the ignition switch turned to ACC or ON.

Adjustable pedals can only operate when A/T shift lever is in P position (except when ignition switch
turned to OFF).

If A/T device (detent switch) error is detected, manual adjustable pedal operation cannot be performed
when ignition switch turns ON.
Automatic OperationEIS004XD
NOTE:

Disconnecting the battery erases the stored memory.

After connecting the battery, insert the key into the ignition cylinder and turn the front door switch LH ON (open)→OFF (close)→ON
(open), the Entry/ Exiting function becomes possible.

After Exiting operation is carried out, return operation can be operated.
NOTE:
During automatic operation, if the ignition switch is turned ON→START, the automatic operation is suspended. When the ignition switch
returns to ON, it resumes.
System DescriptionEIS004XE

The system automatically moves the driver seat and steering wheel to facilitate entry/exit to/from the vehi-
cle. The driver seat control unit can also store the optimum driving positions (driver seat, steering wheel,
pedal position and door mirror position) for 2 people. One-touch operation allows changing between driv-
ing positions.

Function Description
Memory operation The seat, steering wheel, pedals (accelerator, brake) and door mirrors move to the
stored driving position by pushing seat memory switch (1 or 2).
Entry/Exit-
ing functionExiting operation At exit, the seat moves backward and the steering wheel raises. (Exiting position)
Entry operationAt entry, the seat and steering wheel return from Exiting position to the previous driv-
ing position before the Exiting operation.
Keyfob interlock operationPerform memory operation, turnout operation and return operation by pressing key-
fob unlock button.
Auto operation temporary stop
conditions.When ignition switch is turned to START during seat memory switch operation and return
operation, seat memory switch operation and return operation is stopped.
Auto operation stop conditions.

When the vehicle speed becomes 7 km/h (4 MPH) or higher (memory switch operation
and entry operation).

When the setting switch, seat memory switch 1, or 2 are pressed.

When A/T shift lever is in any position other than P.

When the door mirror remote control switch is operated (when ignition switch turned to
ON).

When power seat switch turned ON.

When pedal adjusting switch turned ON.

When front seat sliding Entry/Exiting setting is OFF (entry/exiting operation).
