Digidl Indicator Lights; Vdo And Secondary Can-Bus Enabling - Tachosys digidl Installation Manual

digiDL Indicator Lights

P: Power Status
The digiDL has three indicator LEDs (see Fig 15.) each of which has one of three statuses; ON / OFF or
Flashing. See the table below for details on the meaning of each light status.
LED ON
P Power Okay
C CAN okay
W Comms okay
Please note that when the power LED (Red) is on and the CAN-Bus LED (Green) is o it would sug-
gest that either the CAN-Bus C connector is not connected correctly or the vehicle ignition is o .
If the GREEN LED is not illuminated the Tachograph may not be of the correct type (see page 4-5) or
the manufacturer may not have enabled the Secondary CAN-Bus (CAN2) on the Tachograph (see
below).

VDO and secondary CAN-Bus enabling

Some VDO Tachograph may be con gured with the Secondary CAN-Bus disabled by default. In this
case the function will need to be enabled with a CTC II programmer with 2.6 rmware or later or
Stoneridge Optimo or other suitable Tachograph programmer.
If the CAN LED (GREEN) LED does not illuminate on the digiDL and the Tachograph has a Secondary
CAN-Bus this is the likely cause.
Most DAF models and many Renault models come with the second CAN and Remote Download
turned OFF by default.
