2000 SUZUKI SWIFT relay

6E1-34 ENGINE AND EMISSION CONTROL SYSTEM
FUEL CUT OPERATION
INSPECTION
1) Warm up engine to normal operating temperature.
2) While listening to sound of injector (1) by using sound scope
(2) or such, increase engine speed to higher than 3,000 r/
min.
3) Check to make sure that sound to indicate operation of injec-
tor stops when throttle valve is closed instantly and it is
heard again when engine speed is reduced to less than
about 2,000 r/min.
RADIATOR FAN CONTROL SYSTEM
SYSTEM INSPECTION
Check system for operation referring to Flow Table B-7 in Section
6.
If radiator fan fails to operate properly, check relay, radiator fan
and electrical circuit.
RADIATOR FAN RELAY NO. 2 AND NO.3
INSPECTION
1) Disconnect negative cable at battery.
2) Remove relay(s) from connector(s).NOTE:
Before inspection, check to make sure that gear shift
lever is in neutral position (with A/T model, selector lever
in “P” range), A/C is OFF and that parking brake lever is
pulled all the way up.
WARNING:
Keep hands, tools, and clothing away from engine cool-
ing fan to help prevent personal injury. This fan is electric
and can come on whether or not the engine is running.
The fan can start automatically in response to the ECT
sensor with the ignition switch in the “ON” position.

3) Check resistance between each two terminals as in table
below.
If check results are as specified, proceed to next operation
check. If not, replace.
Radiator fan relay No.2 and No.3 resistance
4) Check that there is continuity between terminals “A” and “B”
when battery is connected to terminals “C” and “D”.
If malfunction is found, replace.
RADIATOR FAN INSPECTION
1) Check continuity between each terminals.
If there is no continuity, replace radiator fan motor.
2) Connect battery to radiator fan motor coupler as shown in
figure, then check that the radiator fan motor operates
smoothly and that fan speed varies.
If radiator fan motor does not operate smoothly, replace
motor.TERMINALS RESISTANCE
