About use of a hand-held diagnostic tester
Tips:
• Before using a diagnostic tester, be sure to read its operation manual carefully.
• Connect the diagnostic tester with the on-vehicle diagnostic interface, and turn ignition
switch to ON position. If the tester can not communicate with the control module normally,
it indicates that the vehicle or tester is malfunctioning.
• If normal communication is enabled when this tester is connected with other vehicles,
you should check power circuits of vehicle diagnostic data cable or control module.
• If neither is normal communication enabled when this tester is connected with other
vehicles, it indicates that the tester itself may be malfunctioning. Please operate
according to the self-diagnostic procedure in the operation manual of the tester.
