sounds will be heard coming from
the engine. This is normal. It
indicates that the vehicle's computer is activating relays,
solenoids, and other components to check their operation.

check its operation. To avoid injury, keep hands or any
part of your body a safe distance from the engine during
this test.

- Check the cable connections at
the CanOBD2&1 Scan Tool and

appropriate for your vehicle, during code retrieval.

successfully a "Code retrieval was successful..." message shows

� The CanOBD2&1 Scan Tool will
display a code only if codes are
present in the vehicle's computer
memory.

KOEO Self-Test, the computer
sends a "PASS" code (code 11 or
111) to the CanOBD2&1 Scan Tool.
