Interpreting the DiCE status LEDs

DiCE has four status LEDs that indicate:

Firmware status
USB communication status
Bluetooth communication status
Vehicle interface status

Fig. 307: The DiCE status LEDs

1. Firmware status

The Firmware status LED can either be red or green. See the table below for details on how to interpret the LED.

Firmware status	Description
Flashing green	DiCE is powered and operational.
Flashing red	Corrupt software or no software. Upgrading of internal software (firmware) is necessary.
Flashing red and green alternately	DiCE is being programmed.
Continuous red	Serious fault in the DiCE unit.
Off	Standby.

2. USB com status

USB com status	Description
Continuous yellow	USB connection connected.
Flashing yellow	USB communication in progress.
Off	Standby.

3. Bluetooth com status

The Bluetooth com status LED is blue. See the table below for details on how to interpret the LED.

Bluetooth com status	Description
Continuous blue	Bluetooth connection connected.
Flashing blue	Bluetooth communication in progress.
Off	Standby.

When DiCE is powered, the status LED for Bluetooth communication flashes quickly for approximately three seconds. If initiation fails, the status LED continues to flash. If no Bluetooth module is mounted on the DiCE unit or if the module is broken, the status LED is never lit.

The status LED for Bluetooth communication has nothing to do with the Bluetooth standard.

4. Vehicle interface status

The Vehicle interface status LED is orange. See the table below for details on how to interpret the LED.

Vehicle Interface status	Description
Flashing orange	Communication on one more of the vehicle's interfaces in progress.
Continuous orange	DiCE Test Unit connected.
Off	Standby.

Flashing orange indicates communication in progress. It is not possible to differentiate between:

Internal communication (DiCE transmits something or loop back test is performed).
Vehicle activity (DiCE not involved).
Communication between DiCE and ECU in the vehicle. The status does not flash if DiCE transmits data without being connected to the vehicle or DiCE Test Unit.
