I have these two codes, cleared the codes but they keep coming back up.

C0575 Left Front solenoid circuit malfunction.

C0580 Right Front solenoid circuit malfunction

I just replaced the ALC Relay, the pump kicks on once when car is first turned on but does not kick on when I load some weight.

I attached the testing for this code. More than likely you have a circuit issue which is causing the module to shut the pump off. Once these codes are set the pump will not run as a safety precaution. It runs initially as a self check so that is normal.

Run through this testing and let me know what you find.
