Scan Module Operation Troubleshooting
The Hardware Status indicators in the lower-right corner of the Home screen provide a quick
reference to wireless operations. The background color of the status indicator icon represents the
condition of the wireless connectivity to that device. Icon status is shown in the table below:
The three light emitting diodes (LEDs) on the faceplate of the Scan Module let you know at a
glance whether or not there is an active connection between the two modules. The two green
LEDs (Vehicle Power and Bluetooth) both flash on and off when the Scan Module and Diagnostic
Tool are actively communicating through a wireless connection. The red Communication LED
flashes on and off when the Scan Module is performing an internal self test, and is illuminated
continuously if a failure is detected (Figure 5-6).
1— Vehicle Power—green LED, flashes during wireless communications
2— Communication—red LED, illuminates if there is a communications failure
3— Bluetooth—green LED, flashes during wireless communications
