2001 SUZUKI GRAND VITARA instrument panel

AUTOMATIC TRANSMISSION (4 A/T) 7B1-7
Diagnosis
This vehicle is equipped with an electronic transmission control system, which control the automatic shift up and
shift down timing, TCC operation, etc. suitably to vehicle driving conditions.
PCM (ECM) has an On-Board Diagnosis system which detects a malfunction in this system and abnormality of
those parts that influence the engine exhaust emission.
When diagnosing a trouble in the transmission including this system, be sure to have full understanding of the
outline of “ON-BOARD DIAGNOSTIC SYSTEM” and each item in “PRECAUTION IN DIAGNOSING TROUBLE”
and execute diagnosis according to “AUTOMATIC TRANSMISSION DIAGNOSTIC FLOW TABLE” to obtain
correct result smoothly.
On-Board Diagnostic System (Vehicle without
monitor connector)
For automatic transmission control system, PCM (ECM) has fol-
lowing functions. Refer to Section 6-1 for details.
•When the ignition switch is turned ON with the engine at a
stop, malfunction indicator lamp (MIL) (1) turns ON to check
the bulb of the MIL.
•When PCM detects a malfunction in A/T control system
(and/or a malfunction which gives an adverse effect to vehi-
cle emission) while the engine is running, it makes the mal-
function indicator lamp in the meter cluster of the instrument
panel turn ON and stores the malfunction area.
(If it detects that continuously 3 driving cycles are normal
after detecting a malfunction, however, it makes MIL (1) turn
OFF although DTC stored in its memory will remain.)
•It is possible to communicate through DLC (3) by using not
only SUZUKI scan tool (2). (Diagnostic information can be
accessed by using a scan tool (2).)

10-2 RESTRAINT SYSTEM
General Description
SEAT BELT WITH ELR
The seat belt with Emergency Locking Retractor (ELR) is designed so that it locks immediately (to prevent the
webbing from being pulled out of the retractor any further) when any of the following items is detected as
exceeding each set value; speed at which the webbing is pulled out of the retractor, acceleration or deceleration
of the vehicle speed, and inclination.
SEAT BELT WITH A-ELR
The automatic and emergency locking retractor (A-ELR) works as an Emergency Locking Retractor (ELR) till its
webbing is pulled all the way out and then on as an Automatic Locking Retractor (ALR) till it is retracted fully.
ALR :
Automatically locks when the webbing is pulled out from the retractor and allowed to retract even a little.
Then the webbing can not be pulled out any further, unless it is wound all the way back into the retractor, which
releases the lock and allows the webbing to be pulled out.
SEAT BELT WITH PRETENSIONER (IF EQUIPPED)
The seat belt with ELR and a pretensioner has a pretensioner mechanism which operates in linkage with the air
bag in addition to the above described ELR. The pretensioner takes up the sag of the seat belt in occurrence of
a front collision with an impact larger than a certain set value, thereby enhancing restraint performance.
DRIVER AND FRONT PASSENGER SIDE AIR BAGS
The driver and front passenger side air bags are components of the air bag system. In occurrence of a front col-
lision with an impact larger than a certain set value, they are activated by the ignition signal from SDM to supple-
ment protection offered by the driver and front passenger seat belts.
•the driver air bag (inflator) module is deployed from the center of the steering column
•the passenger air bag (inflator) module from the top of the instrument panel in front of the front passenger
seat
For more information, refer to Section 10B “Air Bag System”.

AIR BAG SYSTEM 10B-3
General Description
With the air bag system which includes air bags for both the
driver’s and passenger’s sides as well as the seat belt pretension-
ers (if equipped), the sag of the seat belt is taken up (for seat belt
with pretensioner), the driver air bag (inflator) module is deployed
from the center of the steering column and the passenger air bag
(inflator) module from the top of the instrument panel in front of
the front passenger seat in occurrence of a front collision with an
impact larger than a certain set value to supplement protection
offered by the driver and front passenger seat belts.
The air bag system is designed to activate only in severe frontal
collisions. It is not designed to activate in rear impacts, side
impacts, rollovers, or minor frontal collisions, since it would offer
no protection in those types of accidents.
