How to perform a microphone calibration(error B7F500 in RAM)? - rocdeng - 22-01-2023
Hey mates, I met a small problem.
When I diag using ISTA, there are no errors(tree.png), but when I diag using BIMMERLINK or E-SYS Plus, I always got a error in RAM, named 'B7F500 Driver's microphone not calibrated.'(pic2, pic3 and pic4) After clean th DTC, this error always come out the same.
So I'm confused, should I trust ISTA or E-SYS Plus?
If the error truely exists, how to perform the microphone calibration? I tried to find the entry in ISTA but got nothing.
Anyone can help would be appreciated.

Problem SOLVED, I found the entry in RAM function in ISTA and tried to call the microphone calibration. Wish the error code never show again.
