need help with codes
452c - Insufficient input from Programable Speedometer/Odometer Module (PSOM)
I got these under Key On Engine Running:
412r - Cannot control rpm during Self-Test high rpm check
411r - Cannot control rpm during Self-Test low rpm check
311r - Thermactor air system inoperative
538r - Operator error Dynamic Response Test
Any help with any of the codes will be gladly accepted. I'm mostly looking for what some of the thing mean and what they are. I would like to do repairs myself so I will actually learn something rather than taking it to the dealership. Thanks in advance.
