When Monitored & Set Condition

WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.

This code is monitored with the engine running. The engine speed is greater than 1157 RPM. DTC P2503 is set when the battery sensed voltage is one volt below the charging goal for 13.47 seconds. The PCM senses the battery voltage, turns off the field driver and senses the battery voltage again. If the voltages are the same, the code is set.
