Code B336, Loss Of IPC Serial Data

This code can only be viewed as a "history" code because if it were current, service diagnostics could not be entered. Since serial data and ground terminals are redundant, it would take a double open in any of those circuits to set the code. A single intermittent open in circuit No. 750 would also set this code.

If codes are intermittent, check all terminal contacts carefully prior to replacing any parts.
