Communications Error Troubleshooting
Errors 30 through 33 all indicate the loss of communications or erratic communications
between the Upper PCA "
UPCA
1
" and the Lower PCA " LPCA
2
".
The main reason for a general communication error is a faulty interconnect cable, either it is
not connected securely, or it has become damaged. Error 30 can be caused by an overloaded
or s3.3 Vdc or +5 Vdc on the lower PCA, which can be caused by an external com-
ponent plugged into the lower PCA. Error 32 is often caused right after service or installation,
when the interconnect cable is unplugged from the upper PCA while the lower PCA is
powered. It is also caused when the cable is plugged into the
CSAFE
3
port on the upper PCA.
