WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “Gener-
al Description” in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either of these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

The ignition system used for this vehicle has an elec-
tronic ignition control system and consists of the fol-
lowing parts.

ECM
It detects the engine condition through the signals
from the sensors, determines the most suitable igni-
tion timing and time for electricity to flow to the pri-
mary coil and sends a signal to the power unit.

Power unit (Igniter)
It turns ON and OFF the primary current of the igni-
tion coil according to the signal from ECM.

Ignition coil
When the ignition coil primary current is turned OFF,
a high voltage is induced in the secondary winding.

Distributor
It distributes a high voltage current to each plug.
High-tension cords and spark plugs.

CMP sensor (Camshaft position Sensor)
Located in the distributor, it converts the crank angle
into voltage variation and sends it to ECM. For its
details, refer to Section 6E1.

TP sensor, ECT sensor and MAP sensor
For their details, refer to Section 6E.
In electronic ignition control system, the ECM is pro-
grammed for the best ignition timing under every en-
gine condition. Receiving signals which indicate the
engine condition from the sensors, e.g., engine revo-
lution, intake air pressure, coolant temperature, etc.,
it selects the most suitable ignition timing from its
memory and operates the power unit.
Thus ignition timing is controlled to yield the best en-
gine performance.
For more information, refer to Section 6E1.
SECTION 6F
IGNITION SYSTEM
WARNING:
For vehicles equipped with a Supplemental Inflatable Restraint Air Bag System:

Service on or around Air Bag System Components or Wiring must be performed only by an authorized
Suzuki dealer. Please observe all WARNINGS and SERVICE PRECAUTIONS in Section 9J under “On-
Vehicle Service” and the Air Bag System Component and Wiring Location view in Section 9J before
performing service on or around Air Bag System Components or Wiring. Failure to follow WARNINGS
could result in unintended air bag deployment or could render the air bag inoperative. Either of these
two conditions may result in severe injury.

SDM can maintain sufficient voltage to cause a deployment of air bags for up to 10 seconds after igni-
tion switch is turned to “LOCK” position, battery is disconnected or fuse powering SDM is removed.
Work must be started after 15 seconds from the time.
