DTC B2750: Pass-Key(R) II Data Communication Malfunction: Testing

Using scan tool, check for DTCs. If DTC U1016 is also set, diagnose and repair it first. If PCM DTC P1604 is set, diagnose and repair it first.
DTC B2750 may be caused by a password mismatch between IPC and PCM. If this condition exists, PCM DTC P1631 will also be set. Reprogram IPC. See REPROGRAMMING IPC under PROGRAMMING.
