2000 SUZUKI SWIFT steering

MAINTENANCE AND LUBRICATION 0B-21
[Parking brake]
Check that lever has proper travel.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and
brake lever is pulled all the way.
Steering

Check to ensure that steering wheel is free from in-
stability, or abnormally heavy feeling.

Check that the vehicle does not wander or pull to
one side.
Engine

Check that engine responds readily at all speeds.

Check that engine is free from abnormal noise and
abnormal vibration.
Body, Wheels and Power Transmitting System
Check that body, wheels and power transmitting sys-
tem are free from abnormal noise and abnormal
vibration or any other abnormal condition.
Meters and Gauge
Check that speedometer, odometer, fuel meter, tem-
perature gauge, etc. are operating accurately.
Lights
Check that all lights operate properly.
Windshield Defroster
Periodically check that air comes out from defroster
outlet when operating heater or air conditioning.
Set fan switch lever to “HI” position and mode lever to
defroster position for this check. WARNING:
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property damage.
Be prepared to apply regular brake quickly
even if vehicle should start to move.

When not using SUZUKI scan tool:
1) Turn ignition switch ON.
2) Check for voltage at terminal C01-5 of ECM
connector connected, under above each condition.
Is each voltage as specified?Signal circuit is in
good condition.Go to Step 2.
2Check Wire Harness.
1) Turn ignition switch OFF and disconnect PSP switch
