Adjustment of
Car speed detection device


If the circuit is finished assembling you carry out fundamental confirmation that is no error of wiring, confirmation of power supply voltage etc.
After that, the following point is adjusted.

The adjustment of detection speed needs to carry out cause the car run.
Person who drive the car and person who it adjusts cooperate and sufficiently confirm safety.



Adjustment of the door lock signal preparation circuit



Adjustment of door lock speed of the car



Adjustment of additional stop lamp flickering start speed



Adjustment of car speed detection voltage

The car speed pulse signal


Calculation of R15


Calculation of R26 and also R27


Change of the car speed and detection voltage in the production work

( In the case that it installed to my car )
