Action
The starter voltage is normal and the battery is fully charged.
The starter voltage is low and the battery is fully charged.
The starter voltage is low and the battery is discharged. Fully charge the
battery and repeat the starter system test.
(If the battery test result was (REPLACE or BAD CELL.) The battery must
be replaced before testing the starter.
The engine didn't start and the test was aborted.
The EXP didn't detect the vehicle's starting profile and skipped the Starter
Test.
