Verify that the data link adapter is communicating with the selected protocol.

For INSITE™ electronic service tool errors 5200, 5202, and 5023:

• Verify that the power light is on or flashing.
• Verify the communication light is on or flashing when transferring information from the computer to the electronic control module (ECM).

For INSITE™ electronic service tool errors 5201 or 5204 (Data Link J1587/J1708 connections):

• Verify that the specified protocol light is flashing.

If it is not flashing, check the voltage level from the engine. Go to the appropriate wiring diagram for details.
