How to fix Ford Automobile Accessories VCM II when it will not power on?
- VvwhiteAug 17, 2025
If your Ford Automobile Accessories VCM II won't power on, ensure secure cable connections between the VCM II and the vehicle DLC or PC USB port. Check for any bent, broken, missing, or dirty/corroded cable connector pins or connector pins on the VCM II unit. Verify sufficient battery voltage (12V nominal) at the vehicle DLC. If powering from a PC USB port, ensure the port has power, or try a different port. If the boot-up fails after 5 seconds, attempt to recover the software. If the issue persists after these checks, contact your regional technical support.
