c. After adjusting the parameters, reboot the system and check the slack
loop number as in Step 4. If the slack loop number is still low, perform
steps "a" thru "c" again until required number is reached.
6. If the number of loops formed is less than four and the bridge speed
parameters are at nominal values, an adjustment to the slack loop flag is
needed.
a. Remove the lower bridge front cover and inspect the slack loop
bracket/flag and sensor. check to see that the slack loop flag swings
freely through the sensor with no binding.
b. Adjust the slack loop bracket back and forth to create a larger or
smaller slack loop. Refer to Figure 2.
c. Reinstall the front cover loosely with one screw on each side. Reboot
the system and check the slack loop number as in Step 4. If the slack
loop number is still below four, perform steps "a" thru "c" again until
the number reaches at least four.
NOTE: If the slack loop number never goes above "0", there may
be a problem with the sensor. Use AVDIAG's "Sensors" test
to verify that the sensor will go active and inactive.
