I brought a new battery, alternator, starter, spark plugs, and water pump but my battery light still comes on and shuts off after 5 minutes of driving. AutoZone gave me the codes C0040, C0899, and P0528.

Good afternoon.

The PCM can't control the cooling fan, it will trigger the P0528 code. So it sounds like the fan motor is bad. The other codes are ABS and indicate you have a failed ABS module. The charging system diagram is attached. Check the voltage at the back big terminal of the alternator for power.

Did AutoZone check the charging system?
