Hello

1.4 ohms   Diagnostic > 31 (brown/black) > to diagnostic connector pin 1 >removed connectors only continuity test
If your meter is right, I would  look for this to get it down > corrosion?
Pin 1 on diagnostic connector is a brown with a black line. Here is where I measure to pin 31 of ABS connector.
Otherwise your ABS module is down :-[

Pin 4 is all brown > Bike ground > connected with battery minus

Schuppi,

Can I test speed sensors at iabs module connector? from the wiring schematics, pins 33 and 35 are for front and 34 and 36 for rear.
What should I read in ohms for those pins 33-35 and then 34-36?

schuppi:
Hello

Sorry not measurable with your multimeter.
These are Magneto-resistive sensors which cannot generate a signal voltage on their own.
They must have an external power source, provided by the ABS-module.
If your ABS is still not readable, there also will be no output for the sensors.
Checking the sensors an oscilloscope is required.

Only cable resistance measurable.

mayojuaf:
that is why my "invention is not working to test the new sensor....what if i connect my extra battery also?
the meter will read 12 v but when I spin the wheel it will read more than 12?

schuppi:
Hi

I do not know, if that would work :o outside the complete wiring. Never tested it.
But the output of these sensor is in the range of 0,6V to 1,6V when transmitter wheel runs past the sensor.

Checking the sensors an oscilloscope is required.
