Getting Started:
Before you use Scan Tool on the vehicle, please ensure that mechanical problems such
as low oil level, damaged hoses, wiring or electrical connections are fixed FIRST. They
may cause a fault code to set.
The following Areas need to be checked before starting any test:
¾ The levels of engine oil, power steering fluid, transmission fluid (if auto
transmission), engine coolant and other fluids must be at proper level. Top up if
necessary.
¾ Check the condition of air hoses and the air filter must be cleaned. Replace if
necessary.
¾ Make sure the timing belts are in good condition and properly tensioned.
¾ Make sure the spark plugs are cleaned and in good condition. Check for loose,
damaged, disconnected or missing plug cables.
¾ Make sure that all mechanical linkages to the engine sensors (throttle, gearshift
position, transmission, etc) are secure and properly connected. Refer to Service
Manuals for locations.
¾ Check all electrical wirings and harnesses for proper connections and condition of
its insulation.
¾ Check all rubber hoses (radiator) and steel hoses (vacuum and fuel) for leaks,
cracks, blockage or other damages.
¾ Make sure the engine is mechanically sound. Do a compression check, engine
vacuum check, timing check, etc.
¾ Always refer to the manufacturer’s Service Manual
if you are not sure of the repair procedures.
