Steps:

Error Code / Description: Communication issues with the Vocom adapter (88800300) unit. Note that the Help menu in Tech Tool contains details on the Vocom functionality.

Steps to resolve:
1.Check that all the LED’s flash briefly when powering up the unit.

2.The top LED (PC) is green. When connected to the PC and Tech Tool is running, this light should flash intermittently when communicating.
