Fault Codes

[alan robertson]

I have connected the Rovergauge to my ecu. I appear to be getting readings from all sensors and can control the idle valve. I can see a lot of historical error codes but when I try to clear them it does not work. The message says the codes have been cleared but they are still there. Also do the readings shown in the second photo look ok? I have no clue as to what the "normal" readings are. Any help greatly appreciated.

If the ECU is still detecting a fault, the corresponding fault code will be immediately set again and it will look as though it was never cleared. It will only stay cleared if the problem has been corrected. Which fault codes are you seeing? In your photo, I don't see any of them set -- the red lamps all appear to be off.

The sensor readings in your second photo all appear to be normal for idle conditions.

Looking at your message again, I think I understand the confusion. The error code screen isn't showing historical error codes -- it's showing all possible fault codes and the red lamp to the left of each one indicates whether that fault code is set. It appears that your ECU has no fault codes set.

Thanks for clearing that up. I did think that it seemed to be a lot of fault codes. :-)
