To check the control unit use plug socket tester -V.A.G 1537/

A-

⇒ “5.4.3 Final control diagnosis trailer detector control unit

J345 ”, page 301

The trailer detector control unit -J345- etects from a power draw

of minimum 5 W

the “trailer operation” and transfers this infor‐

mation to various control units via the CAN databus.
The trailer detector control unit -J345- is supplied with information

(light control) from the onboard supply control unit -J519- and

convenience system central control unit -J393- via the CAN.

4) At least the turn signal and brake light must be switched on, in order to detect

“trailer operation”.

Fault detection and fault display:
The trailer detector control unit -J345- is equipped with self-diag‐

nosis, which is designed to ease fault finding.
For fault finding, use the vehicle diagnosis, testing and informa‐

tion system -VAS 5051A- in “guided fault finding” mode.
