The system test rst evaluates the battery, then the starting
and charging systems.
IMPORTANT: When you start a new test, the last test results in
memory are overwritten. Remember to record or print
the results if you need to retain them.
Battery Test
The System Test includes a test of the battery to eliminate it as
the cause of starting or charging problems. See Chapter 6 on
page 22 for the Battery Test procedure.
Starter System Test
The performance of the starter and charging systems depends
on the battery’s condition. It is important that the battery is
good and fully charged before any further system testing.

tect the vehicle’s starting prole and display the

select STARTED, the analyzer skips to the Charg-
ing System Test. If you select NO START, the test
