Battery Charger A Cooling System Performance

Check these first

• A charger A cooling fan or pump that is not moving enough air or coolant
• A blocked or restricted cooling path at charger A
• Low coolant or air trapped in the charger cooling loop
• A failing charger A that runs hotter than the cooling can handle

What to do next

1. Command the charger A cooling fan or pump and confirm it runs
2. Check the cooling path for blockage and flow
3. Check coolant level and bleed air from the loop
4. Watch charger A temperature under load
5. Service the cooling component or charger A if temperature stays high
6. Clear the code and retest
