P23B4 Error Code
DEF Supply Module Heater Temperature Fault is the main cause of P23B4 error.The condenser converts gases into liquids, which expels heat from your rig. Materials can build up over time, causing a layer of dirt and grime to form on the condenser's coils. Your AC system will only blow hot air since the refrigerant fails to cool down.
