ABS Fault Code Test Box
By: Andries van den Broek
In the ABS faultcode text of Brian Curry was it not possible make the faultcode visible with a lamp only with a multimeter.
So I decide to make it easy to count the faultcode by using a LED. It is not expensive only a little of time for making this box.
Necessaries materials ABS faultcode read out LED:
If you wanted to make it suitable for the Hall ignition time measurement K-Series, as describe in the Clymer book you need to have a switch On-Off.
- Small box
- Fuse holder and fuse
- 2 Resistors of 1 k-ohm
- 1 LED Red or the color you wanted, max Amp diode 20 mA, U-diode 1.6 - 2.7V
- 1 NPN Transistor BC 547 A
- 1 12 volt connector male like your BMW 12 Volt connector
- 3 Round 4 mm banana connectors female: 1 Red, 1 Blue, 1 Black, placing the banana connectors in the boxside
