ANCEL Truck Scanner Adapter, 9-Pin

Highlights

When a diagnostic tool needs access to J1939 data through a different CAN channel, this adapter is designed to reroute CAN3 to CAN1 or CAN1 to CAN3. It connects a scanner to a vehicle’s 9-pin diagnostic port.

Its stated compatibility covers 2016+ PACCAR Peterbilt and Kenworth trucks, along with Cummins engines. That makes it a targeted cable for specific diagnostic setups, rather than a general-purpose adapter for every truck.

The cable uses a black 9-pin end for the scanner and a green locking connector for the vehicle. The housing is ABS, and the product description also cites flexible construction and heat resistance. Keep in mind that DPF regeneration is described specifically for use with the ANCEL HD110, the adapter alone is not presented as a regeneration tool.

Best use cases

This is most relevant when your truck and diagnostic setup match the listed CAN routing and 9-pin connection requirements. It may help when a scanner needs the CAN1/CAN3 signal routed differently to access J1939 data on an earlier vehicle system. Check the truck, engine, diagnostic port, and scanner requirements against your setup before choosing it, the compatibility list is specific, not universal.

For a practical example, a technician connecting a scanner to a compatible truck can plug the black end into the tool and the green connector into the vehicle’s diagnostic port, then use the scanner for the available diagnostics. The locking connector is intended to maintain a secure connection during that work. It makes sense if you already have a compatible scanner and need this particular connection arrangement. Not the best choice if you need a standalone scanner or an adapter for a vehicle outside the stated compatibility.

Tips for day-to-day use

Match the connector and CAN routing to the diagnostic task before plugging in. The description calls for connecting the black 9-pin end to the scanner and the green end to the vehicle’s diagnostic port, avoid assuming that a matching-looking connector confirms compatibility with a different truck or tool.

If DPF regeneration is your reason for buying, note the stated condition: the adapter enables that function when used with the ANCEL HD110 on 2016+ PACCAR Peterbilt and Kenworth trucks. For other scanners or vehicles, the provided details do not confirm that capability. The cable’s ABS construction is intended for flexibility and heat resistance, but no cable length or additional durability rating is specified.

Practical doubts

What does CAN1/CAN3 rerouting do? It changes the routing between CAN3 and CAN1, allowing compatible diagnostic tools to access J1939 data on earlier vehicle systems.

Which connection does it use? It has a black 9-pin end for the scanner and a green connector for the vehicle’s diagnostic port.

Can it support DPF regeneration? The described DPF regeneration use requires the ANCEL HD110 and a 2016+ PACCAR Peterbilt or Kenworth truck.

Should you buy it?

Choose this adapter if your truck, 9-pin diagnostic connection, and scanner match its stated use, especially if you need CAN1/CAN3 rerouting for J1939 access. The specific HD110 pairing may also suit buyers seeking the described DPF regeneration function. If your setup falls outside those details, or you need broader vehicle coverage, a more general diagnostic solution is the safer direction. On the spec sheet, its value is in solving a particular connection problem—not replacing a scanner or guaranteeing compatibility across heavy-duty vehicles.
