Troubleshooting Communications Errors
Error 30, 31, 32 and 33 - Communications Error
Description
Errors 30 through 33 all indicate the loss of communications or erratic
communications between the microprocessors in the upper PCA and the
lower PCA. The trouble shooting procedures for all of the communication
errors are essentially the same.

Error 30 is defined as upper PCA not receiving from lower PCA.

Error 31 is defined as faulty data received from lower PCA.

Error 32 is defined as lower PCA not receiving from upper PCA.

Error 33 is defined as faulty data received from upper PCA
Possible Causes
1
An upper PCA to lower PCA interconnect cable is bad.
2
The interconnect cable at the upper PCA was mistakenly plugged into
the CSAFE connector.
3
+5V DC power supply is being overloaded by another component that is
plugged onto the lower PCA.
4
A defective lower control module.
5
A defective upper PCA.
Possible Remedies
1
Substitute a know good interconnect cable between the upper and
lower PCAs to determine if the interconnect cable is defective.
2
Remove the interconnect cable from the CSAFE connector and insert it
in the correct upper PCA connector.
3
Unplug all the components from the upper PCA and lower control
module except, data cable, and the AC power going to the lower
control module. If the unit shows an error other than a
communication error, plug in components one at a time, cycling power
after each new component is plugged in. If a communication error is
displayed, the last component plugged in is the cause of the error.
4
Substitute a known good lower control module to determine if the
lower control module is defective.
5
Substitute a known good upper PCA determine if the upper PCAs
defective.
