The front brake schematic you posted is for the passenger / right side. Here’s the driver / left side:
This’s the ABS (speed) sensor as described by the part name. And there’re 4 ABS speed sensors on 4 wheel hubs at 4 corners.
There’s only one vehicle speed sensor (VSS) located at transmission output shaft area.
You can’t use one LF ABS speed sensor to decide the actual vehicle speed as one wheel could be spinning or stopped due to road conditions or braking which will give the PCM a false info on vehicle speed.
The P0500 code is from VSS malfunctioning, not from ABS sensors. Your mechanic somehow figured out the LF ABS sensor is at fault which caused all the warning lights. But definitely isn’t from P0500 code.
BTW, I seem to remember some reports that a bad ABS sensor would cause multiple warning lights like yours. But usually those CX-5’s are much older with much higher mileage.
My theory is that the scan tool used by @Jef garbled up the code and description, but the one used by the pro did not. OBD code C0500 is a perfect match to the resolution of the problem. Before retiring, I spent a lifetime writing and looking at computer code, and know how easy it would be for someone to mistakenly assign that 0500 as a 'P' instead of a 'C', while building the text block for the output display description for the code. Just another simple coding error that didn't get caught in the testing phase.
But IMO this is not in any way important enough to belabor it any further, so I'll just be leaving at that - nothing but my own theory.

Can I ask you a question though? I thought there’s no specific error code to assigned to each of these 4 ABS sensors but this C0500 does pinpoint to the “left front” ABS wheel speed sensor. Are there other 3 codes for the rest 3 ABS sensors?
I don't have an answer for you on that. I only arrived at the C0500 when it occurred to me that all of the ABS-related codes are normally in the 'C' OBD group, so at that point I just took a look at C0500, which happened to match up perfectly to the problem resolution. I suspect there must be similar codes for the other 3 wheel sensors, but don't know that for certain.
Hey man… Hopefully someone searches this mess one day and finds use of it 😂
