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, CPS power 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, careful checking of all terminal contacts is required prior to any parts being replaced.

Code B336 indicates an intermittent loss of IPC data has occurred. Should intermittent problems persist, Check the following circuits for opens or poor terminal contact. If intermittent problem are still present, replace IPC.
