Starter System Test Results
Figure 15: Normal Cranking Result
Table 2: Starter System Decisions and Recommendations
Decision Action
CRANKING NORMAL The starter voltage is normal and the battery is fully charged.
LOW VOLTAGE The starter voltage is low and the battery is fully charged.
CHARGE BATTERY The starter voltage is low and the battery is discharged. Fully charge the
battery and repeat the starter system test.
REPLACE BATTERY (If the battery test result was (REPLACE or BAD CELL.) The battery must
be replaced before testing the starter.
LOW CRANKING AMPS The starter voltage is high but the cranking amps are low.
NO START The engine didn’t start and the test was aborted.
CRANKING SKIPPED The EXP didn’t detect the vehicle’s starting prole and skipped the Starter
Test.
