●After checking the display, touch “ERASE”.
●If any malfunction is displayed on “SELF-DIAG [CURRENT],
repair or replace the malfunctioning again.
11. Touch “BACK” key of CONSULT-II to “SELECT SYSTEM”
screen. Touch “SELF-DIAG [PAST].
12. Check that no malfunction is detected on “SELF-DIAG [PAST].
●If any malfunction is deployed, Touch “ERASE” in the “SELF-
DIAG [CURRENT]” screen, and check the display.
13. Turn ignition switch OFF, then turn off and disconnect CONSULT - I I .
14. Turn ignition switch ON, and check the system with the SRS air bag warning lamp (User mode).
15. Check that no malfunction is detected. Now the diagnosis is complete.
DIAGNOSTIC PROCEDURE 3
Inspecting SRS Malfunctioning Record
If any malfunction is detected in "SRS Operation Check", but no malfunction is detected in “SELF-DIAG [CUR-
RENT]” on CONSULT-II, carry out the following steps.
1. CHECK BATTERY VOLTAGE
Disconnect both battery cables and check that the battery voltage is 9 V or more.
OK or NG
OK >> GO TO 2.
NG >> Charge the battery.
2. CONSIDER POSSIBILITY OF NOT ERASING SELF-DIAGNOSTIC RESULT AFTER REPAIRING.
Is it the first time for maintenance of SRS?
YES or NO
YES >> GO TO 3.
NO >> Erase the self-diagnostic results, and Check the "SRS Operation Check". Refer to SRS-16, "
SRS
Operation Check"
3. CHECK "SELF-DIAG [PAST]" BY CONSULT-II
Store the memory in "SELF-DIAG [PAST]"
YES or NO
YES >> Repair the part of "SELF-DIAG[PAST]"
NO >> Check the "TROUBLE DIAG RECORD", and then repair it. Refer to SRS-21, "

POWER DOOR LOCK — SUPER LOCK —PFP:24814
System DescriptionEIS001R6
OUTLINE
Power door lock system with super lock and key reminder is controlled by time control unit. Super lock has a
higher anti-theft performance than conventional power door lock systems.
When super lock is in released condition, lock knob operation locks or unlocks door.
When super lock is in set condition, lock knob operation cannot lock nor unlock door.
OPERATION
Power door lock/unlock and super lock set/release operation by door key cylinder
●With the key inserted into driver door key cylinder, turning it to LOCK will lock all doors and set super lock.
(Super lock will not be set while key is inserted in the ignition key cylinder.)
●With the key inserted into driver door key cylinder, turning it to UNLOCK will unlock all doors and release
super lock.
Power door lock/unlock and super lock set/release operation by multi-remote controller (If
equipped)
●Pressing multi-remote controller LOCK button will lock all doors and set super lock. (Super lock will not be
set while key is inserted in the ignition key cylinder.)
●Pressing multi-remote controller UNLOCK button once will unlock driver door and release super lock.
Then, if an unlock signal is sent from the remote controller again within 5 seconds, all other doors will be
unlocked.
Power door lock and super lock release operation (by NATS IMMU signal)
●When the super lock is set, turning the ignition key switch to ON will release the super lock. All doors will
unlock once, but then immediately lock again.
Power door lock/unlock operation by lock/unlock switch
●With lock/unlock switch on driver door trim setting to LOCK will lock all doors.
●With lock/unlock switch on driver door trim setting to UNLOCK will unlock all doors.
