and Radiator Cooling Fan Relay Inspection
S6RW0D1306017
1) Disconnect negative cable at battery.
2) Remove main relay (1), fuel pump relay (3), starting
motor control relay (2), throttle actuator control relay
(4) and/or radiator cooling fan relay (5) from
individual circuit fuse box No.1.
3) Check that there is no continuity between terminal

4) Connect battery positive (+) terminal to terminal “B”
of relay. Connect battery negative (–) terminal to
terminal “A” of relay. Check for continuity between

Temperature (IAT) Sensor On-Vehicle
Inspection
S6RW0D1306018
NOTE
Before performed this inspection, be sure to
read the “Precautions of ECM Circuit
Inspection in Section 1A”.

1) Disconnect negative cable at battery.
2) Disconnect MAF and IAT sensor connector.
3) Connect voltmeter to “BLK/RED” wire terminal (2) of
MAF and IAT sensor connector (1) disconnected and
ground.
4) Turn ON ignition switch position and check that
voltage is battery voltage.
If not, check if wire harness is open or connection is
poor.
5) Turn OFF ignition switch position and connect
connector to MAF and IAT sensor.
6) Remove ECM from its bracket referring to “Engine
Control Module (ECM) Removal and Installation”.
7) Connect special tool between ECM and ECM
connector referring to “Inspection of ECM and Its
Circuits in Section 1A”.
8) Turn ON ignition switch position and check MAF
signal voltage between “C01-26” terminal circuit and
“C01-27” terminal circuit of special tool.
MAF signal voltage between “C01-26” terminal
circuit and “C01-27” terminal circuit of special
tool
MAF signal voltage of MAF and IAT sensor with
ignition switch turned ON: 0.5 – 1.0 V
9) Start engine and check that voltage is lower than 5 V
and it rises as engine speed increases.
MAF signal voltage between “C01-26” terminal
circuit and “C01-27” terminal circuit of special
tool
MAF signal reference voltage of MAF and IAT
sensor at specified Idle speed: 1.3 – 1.8 V
10) If check result is not as specified above, cause may
lie in wire harness, connector connection, MAF and
IAT sensor or ECM.

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.
5) Fix ignition timing by using “Fixed Spark Control” of
“Engine / Active Test” mode on scan tool.
6) Set timing light (1) to high-tension cord for No.1
cylinder and check that ignition timing is within
specification.
Initial ignition timing
fixed with SUZUKI scan tool: 5 ± 3° BTDC (at
specified idle speed)
Ignition order
1 – 3 – 4 – 2
Special tool
(A): 09930–764207) If ignition timing is out of specification, check the
followings.
• CKP sensor
• CKP sensor plate
• TP sensor
• CMP sensor
• CMP sensor rotor tooth of camshaft
• Vehicle speed signal from ABS hydraulic unit /
control module
• Knock sensor
• Timing chain cover installation
8) After checking initial ignition timing, release ignition
timing fixation by using scan tool.
9) With engine idling (throttle opening at closed position
and vehicle stopped), check that ignition timing is
about 5° – 15° BTDC (Constant variation within a
few degrees from 5° – 15° BTDC indicates no
abnormality but proves operation of electronic timing
control system.) Also, check that increasing engine
speed advances ignition timing.
If the check results are not satisfactory, check CKP
sensor and ECM.

Scan Tool DataS6RW0D5104008
As the data values given in the following table are standard values estimated on the basis of values obtained from the
normally operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good
condition, there may be cases where the checked value does not fall within each specified data range. Therefore,
judgment as abnormal should not be made by checking with these data alone.
Also, condition in the following table that can be checked by the scan tool are those detected by TCM and output from
TCM as commands and there may be cases where the automatic transaxle or actuator is not operating (in the
condition) as indicated by the scan tool.
NOTE
The following scan tool data related to automatic transaxle can be checked only by communicating
with TCM.
