•Lead wires and hoses of engine/emission control systems
are connected securely.
•Accelerator cable is adjusted.
•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.
•ECM (PCM) does not detect any malfunction DTC.
After above items are all confirmed, check idle speed and IAC
duty as follows.
[Using SUZUKI scan tool]
1) Connect SUZUKI scan tool to DLC with ignition switch OFF.
Special tool
(A) : SUZUKI scan tool
2) Warm up engine to normal operating temperature.
3) Check IAC duty and idle speed by using “Data List” mode of
SUZUKI scan tool.
Engine idle speed:
A/C OFF: 700 ± 50 r/min.
A/C ON: 750 ± 50 r/min.
IAC duty at specified idle speed:
5 – 40 % (at A/C OFF)
4) If duty and/or idle speed is out of specifications, check idle
air control system referring to “DIAG. FLOW TABLE B-4” in
Section 6-1.
5) Check that specified engine idle speed is obtained with A/C
ON if vehicle is equipped with A/C. If not, check A/C ON sig-
nal circuit and idle air control system. NOTE:

Wiper motor
•As shown in the figure, use a 12 V battery to connect its (+)
terminal to terminal “A”, and its (–) terminal to “Black” lead
wire (2).
If motor (1) rotates at a low revolution speed of 45 to 55 rpm,
it is proper. For high speed check, connect battery (+) termi-
nal to terminal “B”, and its (–) terminal to “Black” lead wire
(2). If motor rotates at a high revolution speed of 67 to 83
rpm, it is proper.
•Testing automatic stop action.
a) Connect 12 V battery (+) terminal to terminal “A” of wiper
motor and (–) terminal to Black lead wire (2) and let the
motor turn.
b) Disconnect terminal “A” from battery, and let the motor
stop.
c) Connect terminal “A” and “D” with a jumper wire (3), and
connect terminal “C” to battery (+) terminal. Observe the
motor turns once again then stops at a given position.
d) Repeat a) through c) several times and inspect if the motor
stops at the given position every time.
