Procedure 6.1 - Troubleshooting the Lower and Upper Data
Cable
Typical symptoms associated with a defective data cable are either an error 30 or no power to
the upper PCA. This procedure requires that you have a known good upper data cable, lower
data cable and mid-point connector.
1.
If you are troubleshooting an error 30, 31 or 32 continue with step 2, otherwise see
Procedure 6.3.
2.
Expose the upper top of outrigger tubes by removing the upper and lower display bracket
covers from the rear of the display.
3.
Remove the three bolts that fasten the top, remove the four bolts that fasten the bottom and
remove the clamp from the center of the left outrigger tube. See Diagram 6.1.
Diagram 6.1 - Left Outrigger Tube
4.
There is a data cable in the left outrigger tube, care must be taken when removing the
outrigger tube to avoid damaging the data cable. Carefully remove the left outrigger tube
from the shaft at its center point.
5.
Slide the upper data cable, the cable in the outrigger tube, out of the main frame tube to
expose the mid-point connector and the lower data cable.
6.
Disconnect both cables from the mid-point connector and replace the mid-point connector
with a known good mid-point connector. If the mid-point connector does not correct the
problem, replace the original mid-point connector and continue with step 7. If the mid-point
connector corrects the problem, skip to step 12.
7.
Remove the top, left and right rear covers per procedure 7.1.
8.
Disconnect the lower data cable from the lower PCA and the mid-point connector. Substitute
a known good data cable from the lower PCA to the mid-point connector. It is not necessary
to route the test data cable through the frame tube, for convenience route it externally.
Ensure that the external cable does not interfere with crank arm movement.
