ENGINE AND EMISSION CONTROL SYSTEM (TBI FOR G10) 6E1-33
EVAP CANISTER PURGE VALVE INSPECTION
WARNING:
Do not suck the air through valve. Fuel vapor inside valve
is harmful.
1) With the ignition switch OFF position, disconnect coupler from
EVAP canister purge valve.
2) Check resistance between two terminals of EVAP canister
purge valve.
Resistance of EVAP canister purge valve:
33 – 39 Ω at 20C (68F)
If resistance is as specified, proceed to next operation check.
If not, replace.
3) Disconnect vacuum hoses from intake manifold and its pipe.
4) With coupler disconnected, blow into pipe “A”. Air should not
come out of pipe “B”.
5) Connect 12 V-battery to EVAP canister purge valve terminals.
In this state, blow pipe “A”.
Air should come out of pipe “B”.
If check result is not as described, replace canister purge valve.
6) Connect vacuum hoses.
7) Connect EVAP canister purge valve coupler securely.

EVAP CANISTER INSPECTION
WARNING:
DO NOT SUCK nozzles on EVAP canister. Fuel vapor inside
EVAP canister is harmful.
1) Disconnect vacuum hoses from EVAP canister and remove
EVAP canister.
2) When air is blown into tank pipe, there should be no restriction
of flow through purge pipe and air pipe.
If operation differs from above description, EVAP canister must
be replaced.
3) Install EVAP canister and connect hoses to canister.
TANK PRESSURE CONTROL VALVE INSPECTION
WARNING:
DO NOT SUCK air through tank pressure control valve.
Fuel vapor inside the valve is harmful.
1) Remove tank pressure control valve.
2) Air should pass through valve smoothly from fuel tank side
(black side of tank pressure control valve) to orange side when
blown hard.
3) From orange side, even when blown softly, air should come out
of black side.
4) If air doesn’t pass though valve in step 2) or hard blow is required
in step 3), replace tank pressure control valve.
5) Install tank pressure control valve.
NOTE:
When connecting tank pressure control valve between
hoses, refer to figure at the left for installing direction.
PCV SYSTEM
NOTE:
Be sure to check that there is no obstruction in PCV valve or
its hoses before adjusting engine idle speed, for obstructed
PCV valve or hose hampers its accurate adjustment.
PCV HOSE INSPECTION
Check hoses for connection, leakage, clog and deterioration.
Replace as necessary.

2. Blow air
3. PCV valve
PCV VALVE INSPECTION
1) Disconnect PCV hose from PCV valve.
2) Run engine at idle.
3) Place your finger over end of PCV valve to check for vacuum.
If there is no vacuum, check for clogged valve. Replace as nec-
essary.
4) After checking vacuum, stop engine and check PCV valve for
sticking.
With engine stopped, connect a new hose to PCV valve for in-
spection.
Blow air into the hose and check that air flows with difficulty from
cylinder head side to intake manifold side.
If air flows without difficulty, valve is stuck in “Open” position. Re-
place PCV valve.
WARNING:
Do not suck air through PCV valve. Petroleum substances
inside the valve and fuel vapor inside the intake manifold
are harmful.
5) After removing the hose, connect PCV hose and clamp securely.

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.

IGNITION TIMING
NOTE:
Before starting engine, place transmission gear shift lever in
“Neutral” (shift selector lever to “P” range for A/T model), and
set parking brake.
INSPECTION AND ADJUSTMENT
1) Connect SUZUKI scan tool (1) to DLC (2) with ignition switch
OFF.
2) Start engine and warm it up to normal operating temperature.
3) Make sure that all of electrical loads except ignition are
switched off.
4) Check to be sure that idle speed is within specification.
(Refer to SECTION 6E1)
5) Set timing light to No.1 high-tension cord.
6) Fix ignition timing to initial one as follows:
Select “MISC” made on SUZUKI scan tool and fix ignition tim-
ing to initial one.
7) Using timing light, check that timing is within specification.
Initial ignition timing (Ignition timing fixed):
5 ±3 BTDC (at idle speed)
Ignition order: 1-3-2
Special Tool
(A): 09900-27301 or 09930-76420
8) If ignition timing is out of specification, loosen flange bolts, ad-
just timing by turning distributor assembly while engine is run-
ning, and then tighten bolts.
Tightening Torque
(a): 15 N
.m (1.5 kg-m, 11.0 lb-ft)
9) After tightening distributor flange bolts, recheck that ignition
timing is within specification.
10) After checking and/or adjusting Initial Ignition Timing, release
ignition timing fixation by SUZUKI scan tool.
11) With engine idling (ignition timing not fixed, idle switch ON and
car stopped), check that ignition timing is about 10 BTDC.
(Constant variation within a few degrees from 10 indicates no
abnormality but proves operation of electronic timing control
system.) Also, check that increasing engine speed advances
ignition timing.
If above check results are not satisfactory, check CTP switch,
test switch terminal circuit and ECM.
