Have a 2009 IC with Maxforce DT.
Engine warning light keeps coming on, (yellow triangle).
ESC dash code retrival has five inactive codes.
597
4057
2637
2636
520803
I have not been able to find any info on these codes.
Can anyone help?

depending on the source address and the fmi # i believe 597 has to do with the brake switch 4057,2636 and 2637 have to do with the wiper motor and the 520803 is to do with the park brake relay. those are from ISIS code book #SO8327 but chances are if the yellow triangle is coming on it has a problem with engine protection, emission or doc system any other mil lights coming on? i had that light come on when coolant was not at full mark when eng was at norm oper temp, if there is a sensor in the surge tank. that was on a 2008 with a maxforce DT
