P16E3 ACURA Description

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