How can i test the accelerometer on Infinity IRS Beta woofers?

[Ervikingo]

Left side control woofer is not working. Tried 2 different servo controllers, same situation. Right side works fine.

Control cables test good for continuity.

Going to measure continuity from accelerometer IC to din plug on the speaker but welds look fine.

Thoughts?

IC to socket on speaker 3 leads test OK
