DTC Advanced Diagnostics: P16E8: General Description

The local interconnect network (LIN) line connects the shutter grille 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, the 12 volt battery fan motor, the shutter grille, and the DC-DC converter are the slaves. The shutter grille 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 shutter grille within its specified amount of time, the PCM detects a malfunction and stores a DTC.
