1. Check speed sensor cable and connectors or the port on the back of the
console for loose pins.
2. Clean pins and sockets on speed sensor cable connectors.
3. If no speed sensor extension cable is installed, the speed sensor switch
assembly may require a replacement. Contact a local Raven dealer for
further assistance.
1. Check that the issue is encountered on hard surface roads.
a. If the speed display is accurate on hard surfaces, investigate
mounting the speed sensor on a different wheel.
b. If the speed display is still inaccurate on hard surfaces, proceed to
step 2.
2. Verify that all magnets are detected by the speed sensor by:
a. Removing one set of magnets (one red and one black) from the
wheel.
b. Reposition remaining magnets directly across from each other.
c. Adjust the speed cal by entering a value twice as large as the
correct speed cal value.
d. Recheck speed display on hard surface road.
e. Continue checking sets of magnets (replacing previously removed
set) these two magnets and replace with other two.
f. Run speed check again.
3. If the speed display is inaccurate with only one set of magnets, replace
the bad set.
4. If the speed display is inaccurate with all sets of magnets, replace speed
sensor assembly.
5. Re-enter original speed cal after testing is complete.
