MAF and IAT Sensor InspectionS7RS0B1306020
CAUTION!
Do not heat up MAF and IAT sensor more
than 100 °C (212 °F). Otherwise, MAF and IAT
sensor will be damaged.
• Check sensor O-ring (1) for damage and deterioration. Replace as necessary.
• Blow hot air to temperature sensing part (2) of MAF and IAT sensor (3) using hot air drier (4) and measure
resistance between sensor terminals while heating air
gradually.
If measured resistance does not show such
characteristic as shown, replace MAF and IAT sensor.
IAT sensor resistance
–20 °C (–4 °F): 13.6 – 18.4 k Ω
20 °C (68 °F): 2.21 – 2.69 k Ω
60 °C (140 °F): 0.493 – 0.667 k Ω

Inspection
S7RS0B1306021
Using SUZUKI Scan Tool
1) Connect scan tool to DLC with ignition switch turned OFF.
2) Check “Battery Current” displayed on scan tool at following condition.
Battery current
Ignition switch ON: 6.5 – 7.5 A
Ignition switch ON, headlight ON: 18.6 – 19.1 A
Ignition switch ON, headlight ON and blower
motor switch is HI position: 27.1 – 27.6 A
Engine running at idle speed, headlight ON,
blower motor switch is HI position and rear
defogger switch ON: 38.1 – 41.7 A
If check result is satisfactory, electric load current sensor
is in good condition.
If check result is not satisf actory, check the following
parts and circuit.
• Electric load current sensor circuit (power, ground and output)
• Following charging system components
– Battery (refer to “Battery Inspection in Section 1J”)
– Generator (refer to “Generator Inspection in Section 1J”)
– Generator output control ci rcuit (refer to “Generator
Test (Undercharged Battery Check) in Section 1J”)
– Generator field coil monitor circuit (refer to “Generator Inspection in Section 1J”)
If electric load current sensor circuit and charging
system is in good condition, electric load current sensor
(1) is faulty.

Charging System Circuit
The generator features solid state regulator that it mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brus h holder assembly is attached to the rear housing. The
regulator voltage is being controlled by ECM under some cond itions while driving. Refer to “Generator Control System
Description in Section 1A”.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication.
Two brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal conditions
will provide long period of attention-free service.
The stator windings are assembled inside a laminate d core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes the stator AC. voltages to
a D.C. voltage which appears at the generator output terminal.

Diagnostic Information and Procedures
Brakes Diagnosis NoteS7RS0B4104001
Road Testing Brakes
Brakes should be tested on dry, clean, smooth and
reasonably level roadway which is not crowned. Road
test brakes by making brake applications with both light
and heavy pedal forces at vari ous speeds to determine if
the vehicle stops evenly and effectively. Also drive
vehicle to see if it leads to one side or the other without
brake application. If it does, check the tire pressure, front
wheel alignment and front suspension attachments for
looseness. See diagnosis table for other causes. Brake Fluid Leaks
Check the master cylinder fl
uid levels. While a slight
drop in reservoir level does result from normal lining
wear, an abnormally low leve l indicates a leak in the
system. In such a case, chec k the entire brake system
for leakage. If even a slight ev idence of leakage is noted,
the cause should be corrected or defective parts should
be replaced.
Substandard or Contaminated Brake Fluid
Improper brake fluid, mineral oil or water in the fluid may
cause the brake fluid to boil or the rubber components in
the hydraulic system to deteriorate.

Downloaded from www.Manualslib.com manuals search engine Brake Control System and Diagnosis: 4A-5
If deterioration of rubber is evident, disassemble all
hydraulic parts and wash with alcohol. Dry these parts
with compressed air before assembly to keep alcohol out
of the system. Replace all rubber parts in the system,
including hoses. Also, when working on the brake
mechanisms, check for fluid on the linings.
If excessive fluid is found, replace the pads. If master cylinder piston seals
are satisfactory, check for
leakage or excessive heat co nditions. If leakage is not
found, drain fluid, flush with brake fluid, refill and bleed
system.
The system must be flushed if there is any doubt as to
the grade of fluid in the system or if fluid has been used
which contained parts that have been subjected to
contaminated fluid.
