Malfunction Indicator (MI)EBS0036Q
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON without
the engine running. This is a bulb check.
●If the MI does not light up, refer to DI-43, "WARNING LAMPS"
or see EC-1573 .
2. When the engine is started, the MI should go off.
If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.
On Board Diagnostic System Function
The on board diagnostic system has the following two functions.
Diagnostic Test Mode I - Bulb Check
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to DI-43,
"WARNING LAMPS" or see EC-1573 .

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.
