Interpreting the DiCE status LEDs

 

DiCE has four status LEDs that indicate:

  1. Firmware status

  2. USB communication status

  3. Bluetooth communication status

  4. 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

 

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

USB com status

Description

Continuous yellow

USB connection connected.

Flashing yellow

USB communication in progress.

Off

Standby.

When connecting USB while DiCE is powered, the status LED for USB flashes quickly for approximately three seconds.

The LED Status lamp for USB communication has nothing to do with the USB standard.

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.
