Fault Detection

This terminal is also used by the generator to indicate internal faults. The regulator grounds the "L" terminal when it detects an internal problem. This Changes the value of line 225 in the PCM to low. The BCM detects the ground via the UART data line message from the PCM and commands the battery VOLTS telltale lamp on the IPC ON via UART for analog clusters or displays the BATTERY NO CHARGE message on the DIC for digital clusters. Diagnostic Trouble Code (DTC) P110 code will set.
