What Does the P1682 Chrysler Code Mean?

The Powertrain Control Module (PCM) tries to maintain a system voltage between 12.9 and 15.0 volts. The voltage determined by the PCM as the final goal for the charging system is called "control" voltage. This control voltage is determined from the battery temperature sensor (ambient sensor). The control voltage is compared to the sensed voltage continuously during running. The PCM controls battery voltage by energizing and de-energizing the alternator field winding. When the battery voltage falls below a setpoint voltage, the generator field winding is energized until the battery voltage exceeds a set point.
