CIRCUIT DESCRIPTIONThe Dash Integration Module (DIM) has a designated circuit for monitoring vehicle system voltage. The DIM sends the system voltage status to the instrument cluster via Class 2 message. When the DIM sets B1390, the system voltage status sent to the instrument cluster will default to 12.9 Volts.
CONDITIONS FOR RUNNING THE DTC
Engine speed is greater than 400 RPM.
CONDITIONS FOR SETTING THE DTC
The battery voltage is less than 10.5 volts for 30 seconds.
CONDITIONS FOR CLEARING THE DTC
^ The DTC will clear from current status when the voltage is greater than or equal to 10.5 volts for 30 seconds with the engine running.
^ A history DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present.
^ Use the ON-Board clearing DTCs feature.
^ Use a scan tool.
DIAGNOSTIC AIDS
