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

If #brakeoverride is #ujinga, pause it! #SwitchOn, press both, #brakepedal & #gaspedal, 16seconds or so, then #HapaUjanjaTu 🤷‍♂️

Using #SmartKey, H, & #smartECU, E, from another vehicle, stops at #switchON, not #StartEngine🫣!

#HapaUjanjaTu, do more nonsense #ujanja 👇

X) Whether #IgnitionKey is #switchon, #switchoff, as long as the #carbattery is still connected, some #controlunit's still 'kinda' be powered🤷!

Could be the #BCM for the body, #ECM for engine or whichever🤷, depending on the #controlsystem as this👇 rubbish demonstrates #ecu nonsense👇

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!
