\nThe Jaltest JDC112A is the orange T-connector that in the 7-pin connection between towing vehicle and trailer. One arm carries a plug with seven brass pins, the other arm the corresponding 7-pin connector, and on the side there is JDC 112Ain moulded plastic. At right angles to this is a black block with a short cable running from it to a roundblack 9-pin Deutsch connectorwith abayonet collar, of which four of the nine positions are occupied. That free end is therefore not a 16-pin OBD2.\n

\nOn the 9-pin Deutsch connector, you connect your own 9-pin Deutsch diagnostic cable to the interface; in the product photo that is the version with the green coupling ring. This brings the equipment to PLC communication to SAE J2497 standard: The trailer then does not transmit its diagnostic data via a separate data bus, but over the power supply line of the lighting, the way trailer braking systems particularly in North Americareaches trailers without their own CAN diagnostic connection. The adapter is rated for theJaltest Link V8.1 and V9 and falls under Jaltest CV (commercial vehicles).\n

KEY BENEFITS

Opens the PLC communication to SAE J2497 standard, whereby the trailer transmits its data via the lighting power line.
Remains in the 7-pin connection Pins on one arm, sockets on the other, keeping the tractor and trailer connected.
Compatible with the 9-pin Deutsch diagnostic cable you already have for commercial vehicles.
Reaches trailers without dedicated CAN diagnostic connection, communicating solely via power supply lines.

IMPORTANT NOTES

The free end is a 9-pin Deutsch connector not a 16-pin OBD2; you'll need an additional 9-pin Deutsch diagnostic cable to reach the interface.
For trailers with PLC to SAE J2497 only; if the trailer runs CAN on the ISO 7638-1 connector, the JDC110A is the correct choice.
Of the nine positions in the Deutsch connector, only four are populated: this is not a fully wired 9-pin connection.
At a stated size of 18.2 x 26 cm you'll be working at the coupling, not from the cab.

Applications and functionality

Via the PLC line you read out trailer systems that transmit their data over the power supply line. Which units these are varies by trailer and by chassis manufacturer. The list below covers the systems connected to that line.

Control units you can access

  • Control units on the PLC line: Via the 7-pin connection, Jaltest communicates with trailer systems that transmit their data over the power line, including on semi-trailers without a dedicated CAN diagnostic connector.
  • Varies by trailer: Which control units are present is determined by the semi-trailer, not by this adapter.

What you can do

  • Read and clear fault codes: Access the fault memory of connected control units and clear it after repair.
  • View live data: Monitor current sensor and system values in real time.
  • Activate components: Trigger actuators to verify their operation.
  • Parameters, calibrations and service resets: Where Jaltest offers these for the relevant system.

Compatible vehicles and applications

Communication method is what matters, not the manufacturer. This adapter connects to the 7-pin connection carrying PLC according to SAE J2497. This connection is located at the coupling between towing vehicle and trailer, and the adapter sits in between with its orange T-housing.

Application:

  • Semi-trailers and trailers with PLC communication according to SAE J2497
  • All chassis manufacturers using this communication method
  • Year of manufacture is not a factor: Trailers are not subject to OBD requirements, so the connection remains in use on new semi-trailers
💡
Worth knowing: PLC is not fitted to every trailer; many European semi-trailers use CAN via ISO 7638-1 and fall under the JDC110A. You can identify this adapter by the orange T-connector marked JDC 112A and the black 9-pin Deutsch socket on the cable. Check the semi-trailer itself to confirm which braking system is installed before ordering.
