5.5 Troubleshooting
The Scan Module is a wireless communications device that uses Bluetooth technology to transmit
vehicle data to the diagnostic tool without a physical connection. The working range of the
transmitter is about 30 feet (9.14 m). Scan Module operations can be impacted when signal
interference, or some other condition, disrupts or impairs the wireless communication network.
These interruptions are usually temporary and easily repaired.
Indicators of wireless communication interference include:
• Slow Scan Module response accompanied by “Error 101” message.
• Slow Scan Module response accompanied by “Error 404” message.
• “Error Occurred” Message when trying to use the Scan Module.
• “Error Occurred” Message after 20 or more minutes sitting idle, particularly if the devices have
been stationary.
