heater SUZUKI SWIFT 2000 1.G RG413 Service Repair Manual

ENGINE AND EMISSION CONTROL SYSTEM 6E1-15
ON-VEHICLE SERVICE
ACCELERATOR CABLE ADJUSTMENT
With accelerator pedal depressed fully (1), check clearance
between throttle lever (2) and lever stopper (3) (throttle body)
which should be within following specification.
If measured value is out of specification, adjust it to specification
with cable adjusting nut (4).
Accelerator cable adjustment clearance (with pedal
depressed fully)
“a” : 0.5 – 2.0 mm (0.02 – 0.07 in.)
IDLE SPEED/IDLE AIR CONTROL (IAC) DUTY
INSPECTION
Before idle speed/IAC duty check, make sure of the following.
Lead wires and hoses of Electronic Fuel Injection and engine
emission control systems are connected securely.
Accelerator cable has some play, that is, it is not tight.
Valve lash is checked and adjusted according to mainte-
nance schedule.
Ignition timing is within specification.
All accessories (wipers, heater, lights, A/C, etc.) are out of
service.
Air cleaner has been properly installed and is in good condi-
tion.
No abnormal air inhaling from air intake system.
After above items are all confirmed, check idle speed and IAC
duty as follows.
NOTE:
Before starting engine, place transmission gear shift
lever in “Neutral” (shift selector lever to “P” range for A/T
vehicle), and set parking brake and block drive wheels.

HEATED OXYGEN SENSOR (HO2S-1 AND HO2S-2)
OXYGEN SENSOR HEATER INSPECTION
1) Disconnect sensor connector.
2) Using ohmmeter, measure resistance between terminals
“V
B” and “GND” of sensor connector.
If found faulty, replace oxygen sensor.
Resistance of oxygen sensor heater
HO2S-1 : 5.0 – 6.4
Ω at 20°C (68°F)
HO2S-2 : 11.7 – 14.3
Ω at 20°C (68°F)
3) Connect sensor connector securely.
REMOVAL
1) Disconnect negative cable at battery.
2) For HO2S-1, disconnect connector of heated oxygen sensor
and release its wire harness from clamps, then remove front
bumper and heat insulator panel.
3) For HO2S-2, disconnect connector of heated oxygen sensor
and release its wire harness from clamp and hoist vehicle.
4) Remove heated oxygen sensor (1) from exhaust manifold or
exhaust pipe.
INSTALLATION
Reverse removal procedure noting the following.
Tighten heated oxygen sensor (1) to specified torque.
Tightening torque
Heated oxygen sensor (a) : 45 N·m (4.5 kg-m, 32.5 lb-ft)
Connect connector of heated oxygen sensor (1) and clamp
wire harness securely.
After installing heated oxygen sensor (1), start engine and
check that no exhaust gas leakage exists. NOTE:
Temperature of sensor affects resistance value largely.
Make sure that sensor heater is at correct temperature.
1. Viewed from terminal side
WARNING:
To avoid danger of being burned, do not touch exhaust
system when system is hot. Oxygen sensor removal
should be performed when system is cool.
[A] : HO2S-1
[B] : HO2S-2

6H-8 CHARGING SYSTEM
3) Ground F terminal and start engine, then measure voltage at
B terminal as shown in left figure.
Voltage is higher than standard value
It is considered that generator itself is good but IC regulator
has been damaged, replace IC regulator.
Voltage is lower than standard value
Generator itself has problem, check the generator.
LOAD CHECK
1) Run engine at 2,000 rpm and turn on head light and heater
motor.
2) Measure current and if it is less than 20 A repair or replace
generator.
OVERCHARGED BATTERY
1) To determine battery condition, refer to Battery section.
2) If obvious overcharge condition exists as evidenced by
excessive spewing of electrolyte, measure generator B ter-
minal voltage at engine 2000 rpm.
3) If measured voltage is higher than upper limit value, disas-
semble generator.
4) Check ground of brushes. If brushes are not grounded,
replace IC regulator. Then check field coil for grounds and
shorts.
