Power Supply

SUPPORT QUESTIONS

Frequently Asked Questions

How do I check whether my vehicle is supported?
For PCMflash, identify the ECU/TCU and check the relevant module information on the PCMflash page. For JalTool, use the vehicle coverage search on the JalTool page. A vehicle name alone may not confirm every ECU variant or function, so send the exact vehicle and controller details to ARMS for verification.
What should I do if the software displays an error?
Stop and record the exact error message. Do not repeatedly retry a write operation. Send a screenshot, the selected module or vehicle system, the connection method and the ECU/TCU identification to the support team.
Can I use the same connection method for every ECU?
No. Connection requirements depend on the ECU/TCU family and the specific operation. Always confirm the correct wiring diagram and supported method for the exact controller before connecting or programming.
What information is needed for a compatibility check?
Please provide the vehicle make, model, year, engine and a clear photo of the ECU/TCU label. Part number, hardware number, software number and processor information are especially helpful when available.
