A couple of cautions when you are working first time with micro boards.
1) When using a scope make sure ground clip on probe cant accidentally brush up
against other part or board leads or board traces. Make sure when connecting to a ground
on board it stays put. I have hosed more boards than I...
pulse streams of desired width and inter
pulse delay.
Pulses are outputs to a pin to initiate an action like turn on a fan or light. So I make
a pin go high to turn something on, wait for a time delay I set, then make pin go low
to deactivate that specific task/job/event.
Yes, using blocks...
A basic simple approach to a multi triggerable timer, using GUI block programming.

If your new to processors consider block language programming, many have the HCSR04
in their library. Lots of fun, rapid development.
See post #7 general description, youtube has lots of getting started videos...
If you have a DSO place it on infinite persistence, say 100 mV / box, 10 mS to start,
edge triggered around 50 mV, AC coupled, and look at power rails for pk-pk noise.
Type of bypass caps for bulk matter :
OSCON is polymer tant
Use a bulk and a ceramic disk (.1 uF) in parallel.
Is...
Take a well focused pic of ECU with its cover off, component side, and do a google
image search with pic to see if you can get a hit trail to something useful.
The xtal osc can be sensitive to probe loading, so just bring probe tip close to
osc C's or xtal, scope on roughly 100 mv box to see if its running. Probe at 10X.
Can you identify the pin that puts ECU to sleep ? Any documentation on it ?
Have you asked ChatGPT to try to find more docs or...
Per chance do you have a low V Capacitor checker ? They apply a couple 100 mV level of AC
and look for ESR, and exceedingly low ESR is a short in effect.

Cypress, now Infineon owned, has an extensive line of AFM based SOC's. Example
part has all these resources, ,most multiples of whats shown.
Above is PSOC 4/5 families. There is a PSOC 6 family with huge BT resources and capabilities as well.

Also if you can get access to a good optical inspection scope look at soldering, amazing
how much stuff made with marginal solder joints. Look for cracks, areas where solder
does not appear to have "wicked" onto the leads/joints. Both sides of board...

Non specific to your version but general principles apply.
