DTC U3003: Battery Voltage: Description

The PSCM monitors the voltage supplied by the 12-volt battery and charging system and sets the appropriate DTC when necessary.

• DTC U3003:16 (Battery Voltage: Circuit Voltage Below Threshold) - If the voltage supply to the PSCM falls below 9 volts with the ignition ON and with engine speed above 500 rpm, then DTC U3003:16 is set.
• DTC U3003:17 (Battery Voltage: Circuit Voltage Above Threshold) - If the voltage supply to the PSCM exceeds 20 volts for 10 minutes with the ignition ON, then DTC U3003:17 is set.
• DTC U3003:68 (Battery Voltage: Event Information) - If the voltage supply to the PSCM and the battery management message sent by the BCM do not match, then DTC U3003:68 is set.
