ABS and Handbrake Lights Both On

It's a lot more nuanced than that. Again, this is the PH. One's profession here is nowhere near as appreciated (and compensated more) compared to someone working in more developed countries.

Putting it another way, one's profession and know-how here means nothing to your livelihood if you can't turn a profit from fast turnarounds and volume repairs.

The only value of these highly-skilled repair mechanics who have invested in training, tools and diag instruments is in fault-finding complex and even "impossible" problems. But those situations are far in-between and most mechanics would just lean towards replacing statistically failure-prone parts at the get-go.

As a disclaimer, I don't agree to a parts-cannon approach, but that is the nature of the beast. Besides, bad practice notwithstanding, these mechanics yields good-enough batting averages that has evidently kept them in business.

agree. sigh.

nice to have, but "who knows how to use oscilloscopes nowadays?"

I do. But it doesn't mean I'm confident enough to poke at the ECM/PCM/ABS module pins. lol

The subject vehicle in question is a typical four channel ABS/traction controlled system that uses two wire sensors( per channel). You can set your DSO in auto mode(voltage for Y axis and time/frequency for X axis) and adjust either once you capture the waveform. There are tutorials on YouTube on the use of DSO. There are also tutorials from aeswave.com.
