Driver Assist · first connection
Connect your tachograph
to your phone.
Choose the manufacturer. Check the version, prepare the tachograph and start reading data in the app.
Set up while parked. Prepare your phone with an available DDDStart release and insert your driver card in tachograph slot 1. These instructions cover card download and ITS LIVE, not vehicle mass memory download.
01 · VDO compatibility
VDO: firmware 4140 or later required.
This is the minimum requirement for a Bluetooth connection in DDDStart. The Smart 2 label alone is not enough.
Where can I check the number?
On the tachograph, open Display → vehicle → DTCO version and read the firmware version.
You can also select Printout → vehicle → technical data and find the version identifier.
The same version in two formats04.01.40 V 4140
DTCO 4.1a · minimum for DDDStart
04.01.41 / V 4141 is DTCO 4.1b.
04.01.26 / V 4126 is below the minimum.
Have an older version? Ask a tachograph workshop whether your unit can be updated. Pairing your phone does not update the firmware. Available readings depend on the model, tachograph firmware and ITS permissions granted.
I have the right version — continue to pairing02 · VDO DTCO 4.1a / 4.1b
Enable ITS access and pair your phone.
Allow ITS data sharing

Start pairing
Enable Bluetooth on your phone. In the tachograph's driver menu, open Bluetooth, then pairing and connection.
Confirm on both devices
Select the tachograph on your phone. Compare the six-digit codes and accept the matching code on both the phone and tachograph.

Next: open DDDStart02 · Stoneridge SE5000-8.1 Smart 2
Enable Bluetooth and add your phone.
These instructions apply to the Smart 2 model. Not every SE5000 tachograph has the same interface.
Enable the interface
Open SETTINGS → Bluetooth → Allow Bluetooth → YES. Confirm with OK.
Add a new device
In the Bluetooth menu, select Pair new device?. A five-minute pairing window will begin.
Select the tachograph on your phone
In the Bluetooth device list, find SE5000-xxx. Compare the code and confirm it on the phone and tachograph.
Allow data access
In SETTINGS → Driver consent allow personal data export. Then open DDDStart.
Stoneridge connects to one device at a time. Disconnect the previously used phone or app. RHMI consent is for remote entries and is separate from ITS reading.

Next: open DDDStart03 · DDDStart
Pairing is the first step.
Now choose what to read.
Sign in to the app and grant the required Bluetooth permissions. On Android, allow nearby device access; older versions may request location permission for scanning.
DDD file on your phone
Open Download card, select Search for device, then Connect to tachograph. Start the download and wait for confirmation that the file has been saved.
Button names refer to the Android app; the layout may differ by platform and release. DDD file analysis and PDF reports are a separate service in your DDDStart account.
If something isn't working
Check these three things.
The phone cannot find the tachograph
Check the model, the card in slot 1, Bluetooth and app permissions. Restart pairing mode on the tachograph. Do not try to replace a missing interface with a standard Bluetooth adapter.
The phone is paired, but LIVE is unavailable
Check ITS data sharing consent, your DDDStart sign-in and Driver Assist access in your account. Disconnect another app using the tachograph, then reconnect in DDDStart.
The download stops or shows 0 B
Do not treat an empty file as a completed download. Leave the card in the tachograph and keep the app on screen. Try again while parked. If the error returns, use Report a problem in the app.
