i got codes 600, 432 and 1493 i know what the codes mean but i was wandering if there is a fix besides changing the computer for the 600 code

also if anyone has anysuggestions for the other two it would help out greatly
thanks in advance.

1493 is the batt temp sensor voltage too low. This sensor is used to increase/decrease the alt output volts to charge the batt based on the temp near the bat.

432 left front catalyst efficiency failure (below required level)
