LED lamps not working
If the LED lamps don’t light during I/M Readiness testing, do the following:
 Make sure the OBD II cable is connected to the DLC securely.
 Verify the ignition key is in the KOER position.
 Run the LED Test in the System Setup menu. If the tool fails this test,
there is a problem with the LED lamp. Please contact Autel Tech Support
or your local tool distributor.
