Code B336, Loss Of IPC Serial Data

This code can only be viewed as a history code because if it was current, service diagnostics could not be entered. Since serial data, battery 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. 343 would also set the code.

If codes are intermittent, careful checking of all terminal contacts is required prior to any parts being replaced.
