In this useless #App 📱💻 We keep writing certain nonsense on #howto #controlsystems' #sensors #actuators #ecurepair #ecu #repairtips #5021tips #autorepairtips #howtorepair #howitsdone #diy #canbus #diytipsandtricks #carprogramming #autoelectronics #autoelectrical #magari #obd #autodiagnostics #autodiagnosis #autotuning

The #ECU's WXYZ must agree for #enginestart!
V no #keysecurity!
After W verifies the #smartkey, then #switchON!
W is later also verified by Y!
X must be be verified by Y
Z can be married to Y by do the OBDpins 13 & 4!

Input into #controlunit, from #rheostat #sensor it's the rate at which #electrons come in, #current, may be NO reference😏!
For #potentiometer #sensor, it's force electrons come in, #voltage🫣, compared to some known standard force🧐!

On some few systems, turning key #SwitchON could fully #PowerON the #ECU🤔, otherwise it just pings the #ControlUnit send a negative to the #ECUrelay which relays back real power from the battery! As fully explained here👇

Never mistake the Ignition-ON power for that the ECU is getting power! #HapaUjanjaTu
