4. When the cranking condition is detected, the scan
tool will begin collecting DLC voltage readings.

Press ENTER when the engine
has started.
5. If an engine started condition is detected, the scan
tool will collect Key On Engine running DLC volt-
ages.

Determining DLC KOER voltage.
6. The test results are then displayed.
Test Results
DLC Cranking Voltage 7.9
DLC KOER Voltage ---
DLC KOEO Voltage 11.4
Test Results
DLC Cranking Voltage 8.0
DLC KOER Voltage 14.6
DLC KOEO Voltage 11.7
On the first “Test Results” screen example, the Scan
Tool did not detect that the engine had started. Because
of this, there is no KOER voltage reading.
The second “Test Results” screen example did detect
that the engine had started, and a KOER reading is
displayed.
The second “Test Results” screen example shows that
the KOEO voltage before an engine start was attempted
was 11.7V. Once the starter began cranking the engine,
a cranking voltage of 8V was measured. After the engine
started, a KOER voltage reading of 14.6V was measured.
• If the KOEO voltage is very low, this could be an
indication of a bad battery, or one that needs to be
charged.
• If the cranking voltage is a lot lower than the KOEO
voltage, than this is an indication of a worn starter.
• If the KOER voltage is not higher than the KOEO
voltage, than this indicates a bad or weak alternator.
7. After reviewing the test results, press or to

5.14 Vehicle Information
The Vehicle Information function allows the scan tool to
request the vehicle’s VIN number, calibration ID(s) which
identifies software version in vehicle control module(s),
calibration verification numbers (CVN(s)) and in-use
performance tracking.
• Vehicle Information function applies to model year
2000 and newer OBDII compliant vehicles.
• The scan tool cannot verify if data is correct for
scanned vehicles.
• CVNs are calculated values required by OBDII regula-
tions.
• The CVN calculation may take several minutes.
• CVNs are reported to determine if emission-related
calibrations have been changed. Multiple CVNs may
be reported for a control module.
• In-use performance tracking, tracks performance of
key I/M Monitors.

mation is highlighted.
