To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be done
as a set from start to finish.
1. Turn off all loads on the vehicle electrical system.
2. Perform battery and starting system test with Battery/Starting/
Charging system tester.
3. Press “ENTER” to begin the charging system test.
4. Start engine.
5. Press “ENTER” until “LOADS OFF REV ENGINE 5 SEC ” is dis-
played.
6. Raise and hold the engine speed at 1,500 to 2,000 rpm for about 5 seconds, then return the engine to idle.
Once the increase in engine rpm is detected, press “ENTER” to
continue.
NOTE:

If after 30 seconds an increase in engine idle speed is not
detected, “RPM NOT DETECTED” will display.

Some engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect
this without any other action being taken. If this occurs, con-
tinue on with the testing process. The final results will not be affected.
7. The tester now checks the engine at idle and performs the DIODE/RIPPLE check.
8. When complete, the tester will prompt you to turn on the follow- ing electrical loads.

AUTOMATIC DRIVE POSITIONER
Revision: November 20092006 QX56
System DescriptionEIS004XE

Refer to Owner's Manual for Automatic Drive Positioner system operating instructions.

The settings (ON/OFF) of the automatic sliding seat (Entry/Exiting operation) at entry/exit can be changed
as desired, using the display unit in the center of the instrument panel. The set content is transmitted by
CAN communication, from display control unit to driver seat control unit.

Using CONSULT-ll, the seat slide amount at entry/exit setting can be changed.
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.
FAIL-SAFE MODE
When any manual and automatic operations are not performed, if any motor operations of seats or pedals are
detected for T2 or more, status is judged “Output error ”.

DISPLAY ITEM LIST
NOTE:

If park switch error is detected, manual adjustable pedal operation cannot be performed when ignition
switch turns ON.

The displays of CAN communication and detection switch display error detecting condition from memory
erase to the present on “TIME”.
–If error is detected in the past and present error is detected, “CRNT” is displayed.
–If error is detected in the past and present error is not detected, “PAST” is displayed.
–If error has never been detected, nothing is displayed on “TIME ”.

Any items other than CAN communication and park switch count error detection frequency occurred after
erase history to “1-127”.
–If error was detected in the past, error detection frequency from memory erase to the present is displayed
on “TIME ”.
–If error has never been detected, nothing is displayed on “TIME ”.
–Can clear the detected memory.
Normal: Clear memory in normal condition, history is erased and nothing is displayed on “TIME”.
