Hondata OBD1 Socket Tester for Honda OBD1 ECUs like P28, P06
When preparing an ECU for S300/s200 (test s200 socketing using the supplied pins) installation it is very easy to make mistakes. Lifted tracks and dry joints can be very difficult to spot. This tester takes out all the guesswork. Simply plug it in and all LEDs will light up when the pins have a good connection. If a LED is not on, then you have a soldering or wiring problem on the respective pin.
