5.3.2 No Communication Message
If the Scanner is unable to establish a communications link, a “no communications” message
displays. A “no communication” message, means the Scan Module and the vehicle control
module cannot communicate with each other for some reason.
The following conditions cause a “no communication” message to display:
• The Scanner is unable to establish a communication link with the vehicle.
• You selected a system for testing that the vehicle is not equipped with (such as ABS).
• There is a loose connection.
• There is a blown vehicle fuse.
• There is a wiring fault on the vehicle, or in the data cable or adapter.
• There is a circuit fault in the data cable, Personality Key, or adapter.
• Incorrect vehicle identification was entered.
Refer to the Vehicle Communication Software manuals for manufacturer-specific problems.
