Throttle Position Sensor Performance Check
1) Remove air cleaner outlet hose.
2) Turn OFF ignition switch.
3) Disconnect connector from electric throttle body
assembly.
4) Check throttle position sensor (main and sub) output
voltage as following steps.
a) For throttle position sensor (main), arrange 3
new 1.5 V batteries (1) in series (check that total
voltage is 4.5 – 5.0 V) and connect its positive
terminal to “Vin” terminal (2) and negative
terminal to “Ground” terminal (3) of sensor. Then
using voltmeter, connect positive terminal to
“Vout 1” terminal (4) of sensor and negative
terminal to battery.
b) For throttle position sensor (sub), arrange 3 new
1.5 V batteries (1) in series (check that total
voltage is 4.5 – 5.0 V) and connect its positive
terminal to “Vin” terminal (2) and negative
terminal to “Ground” terminal (3) of sensor. Then
using voltmeter, connect positive terminal to
“Vout 2” terminal (4) of sensor and negative
terminal to battery.
c) Measure output voltage variation while throttle
valve is opened and closed as following
specification.If sensor voltage is out of specified value and linear
variation as the following graph, replace electric throttle
body assembly.
TP sensor output voltage
TP sensor (main) [A]: 0.45 – 4.88 V, varying
according to throttle valve opening by finger
(Voltage should vary by 0.04 V for each 1° valve
opening)
TP sensor (sub) [B]: 1.33 – 5.007 V, varying
according to throttle valve opening by finger
(Voltage should vary by about 0.032 V for each 1°
valve opening)

terminal (3) of sensor. Then using voltmeter, connect
positive terminal to “Vout 1” terminal (4) of sensor
and negative terminal to battery.2) For APP sensor (sub), arrange 3 new 1.5 V batteries
(1) in series (check that total voltage is 4.5 – 5.0 V)
and connect its positive terminal to “Vin 2” terminal
(2) and negative terminal to “Ground 2” terminal (3)
of sensor. Then using voltmeter, connect positive
terminal to “Vout 2” terminal (4) of sensor and
negative terminal to battery.
3) Measure output voltage variation while accelerator
pedal is no depressed and fully depressed as
following graph.
If sensor voltage is out of specified value or does not
vary linearly as the following graph, replace APP sensor
assembly.

Input / Output Signal Table of 4WD Control ModuleS6RW0D3201008
4WD control module outputs the following signals to coupling assembly, indicators, according to the 2WD/4WD switch
operation.
On-Board Diagnostic System DescriptionS6RW0D3201009
For 4WD control system, 4WD control module has the following functions.
• When ignition switch is turned ON with engine at stop, 4WD AUTO indicator (1) and 4WD LOCK indicator (2) turn
on at the same time for 2 seconds in order to check operation of these indicators.
• When 4WD control module detects any malfunction in the following area, 4WD AUTO indicator (1) and 4WD LOCK
indicator (2) flash continuously or turn on and 4WD control module comes into fail-safe mode. For details of fail safe
mode, refer to “Fail-Safe Table”.
– 2WD/4WD switch
– Coupling air temperature sensor
– Coupling assembly
• DTC can be checked by using SUZUKI scan tool (3) connected to DLC (4).
• When 4WD control module detects any malfunction, 4WD control module will switch off the current to coupling
assembly and vehicle is changed to 2WD position.

NOTE
For new ABS hydraulic unit / control module
assembly, if “ABS Hydraulic Unit Operation
Check” has not been performed, ABS
warning light may flash when ignition switch
is turned ON position.
Accordingly preform “ABS Hydraulic Unit
Operation Check” to stop flashing of ABS
warning light.

Output Voltage Inspection
1) Disconnect negative (–) cable from battery.
2) Hoist vehicle a little.
3) Disconnect wheel speed sensor connector.
4) Set up measuring device as shown in figure, the
resistance to 115 Ω and the power supply voltage to
12 V.
