Failsafe

Due to a failure in the battery current sensor or battery temperature sensor, the ECM may determine the necessity of performing a fail-safe operation. Then, the ECM stops the charging control and the generator switches to the normal power generation mode.

When the ECM detects a malfunction in a sensor, the ECM memorizes the DTC (Diagnostic Trouble Code). The MIL (Malfunction Indicator Lamp) does not illuminate.
