HUB END REASSEMBLY CONTINUED
26. Check A.B.S. sensor performance as follows :-
Before commencement of this check It is important that the number of teeth be checked
and found to be the correct, on both LH and RH hubs.
a) Insert the probes from a volt-meter into the two plugs in the sensor connector.
b) set the voltmeter to read mili-volts AC.
c) Rotate the hub in any direction at a constant speed of 60Hz (7Kph).
To determine this speed use the following calculation ;
where z = the number of teeth on the pole wheel.
Note :- The reading may not be steady due to the possibility of pole wheel run out and the
inconsistent speed of the wheel.
d) The maximum reading (Vmax) must not be more than 80% greater than the minimum
reading (Vmin). ie.
If the following is true then it is likely that there is excessive pole wheel runout. The pole
wheel installation will therefore need to be inspected and remounted or replaced.
e) The minimum reading must be greater than the voltage threshold (Vt) ie.
If this is not the case, then the sendsor gap is too large or there may be excessive pole
wheel runout. The pole wheel will therefore need to be inspected and remounted or
replaced.
f) If sections d) and e) are satisfied, then the installation can be considered as satisfactory.
Note :- The above test procedure is as recommended by A.B.S. manufacturers.
