Hello, is it compatible with the Nexiq or Online 6?

Hello, is it compatible with NEXIQ or INLINE 6?

Yes, normally Bendix ACom PRO works without issue with RP1210 interfaces, so it is usually compatible with:

• NEXIQ USB-Link 2 / USB-Link 3 (original) → usually works well for ABS/ESP/Wingman, diagnostics, and calibrations.
• Cummins INLINE 6 → can also work if the RP1210 driver is installed and ACom detects it as an RP1210 device.

Keep this in mind:

• If your ACom PRO is in a mode/version that uses J2534, compatibility depends on your interface having a J2534 driver (many Nexiq/INLINE are more “RP1210” than J2534). In practice, ACom is almost always used through RP1210.
• With clones (Nexiq/INLINE clone) it is common for it to connect but fail in advanced functions or flashing.

What to check to confirm it quickly:

• Install the official driver (NEXIQ or Cummins INLINE).
• Open ACom PRO → interfaz/VCI selection → look for your device in the RP1210.
• list. If it does not appear, it is almost always a driver issue (or Windows blocked the driver).

Tell me exactly which one you have (USB-Link 2/3 or INLINE 6), whether it is original or a clone, and which module you are going to work on (ABS/ESP/Wingman/IntelliPark/trailer), and I will tell you the most stable option/driver.

USB-Link 1 and an INLINE 6

USB-Link 1 and INLINE 6

Click to expand...

Of those two:

1) NEXIQ USB-Link 1
It works in many cases for basic diagnostics, but it is old and tends to cause more trouble with modern software (drivers, stability, and some advanced functions). ACom PRO normally detects it via RP1210, not through J2534.

• If ACom sees it in RP1210: it should work for leer/borrar faults and data on the ABS/ESP/trailer, etc.
• For “sensitive” tasks (flashing, calibrations), the USB-Link 1 is more prone to failure than USB-Link 2/3 or INLINE.

2) Cummins INLINE 6
It usually works better and is more stable. It also works through RP1210 (by installing the Cummins driver). For ACom PRO, it is normally the recommended option between those two.

What I recommend you do (quickly and without guessing)

• Install one driver at a time and test it (to avoid RP1210 conflicts).
• In ACom PRO, go to the interface selection and look for the device under RP1210 (you should see something like “NEXIQ USB-Link” or “Cummins INLINE 6”).
• If both appear, try the INLINE 6 first for everything important.

Key question
Is ACom PRO showing you the list of RP1210 interfaces, and which one exactly appears there? If you tell me what appears on that screen (device name) and whether it is for the tractor or trailer (ABS/ESP/Wingman/IntelliPark), I can tell you which one is best and which driver version usually causes fewer problems.
