failure
1. Fault codes 01 and 02 indicates problems with the comm
board pca. To clear the fault:
2. Check cable that connects to the comm pca to the main
pca and try action again.
3. Turn off the Controller and disconnect and reconnect the
cable connecting the comm pca to the main pca and cycle
power.
4. Replace the wire that connects to the comm pca to the
main pca.
5. Replace comm pca. See Chapter 4 for Controller part
replacement procedures.
Fault codes 21 through 23 indicate problems with the main pca.
To clear the fault, reset from on-screen error message and try
again. If the reset does not clear the fault, replace the main pca
and try again. See Chapter 4 for Controller part replacement
procedures.
Fault codes 31 through 36 indicate problems with the
microprocessor pca. If any of these faults show, there is a
problem with the microprocessor pca and it must be replaced to
clear the fault. See Chapter 4 for Controller part replacement
procedures.
