Stratus L4-2.4L DOHC (1995)
Charge Lamp/Indicator: Description and Operation
The PCM sends a message over the CCD Bus to the Body Control Module (BCM). The BCM turns the instrument panel Charging System Lamp
on. Refer to Charging System for more information.
CIRCUIT OPERATION
The Charging System lamp is used to alert the operator that the charging system voltage has fallen below the normal operating range. When the
Powertrain Control Module (PCM) determines a problem, a message is sent across the CCD Bus to the Body Control Module (BCM).
The BCM processes this message and sends a signal on the CCD Bus to the instrument cluster for lamp illumination. This lamp also is illuminated,
for a few seconds, when the ignition switch is moved from the OFF to the RUN position as a bulb check.
