Code P16E2 Acura Description

The local interconnect network (LIN) line connects the alternator and the Powertrain Control Module (PCM). The LIN uses a master/slave protocol to send and receive data to the different components on the line. The PCM is the master unit, which controls the engine electrical system. The alternator is the slave. The alternator receives data from the PCM and provides feedback to the PCM, which allows the PCM to operate the engine electrical system efficiently. When the PCM does not receive signals from the alternator within its specified amount of time, the PCM detects a malfunction and stores a DTC.
