Disable DTC errors SID20x LandRover Discovery 2.7TD

by **sa.bondarenko** » Fri May 08, 2015 12:11 pm

Hi All,
I have a dump of my ECU (read by KESS I believe) and looking a way to disable EGR-related fault codes - P0405 and P140A.

Could someone explain how to identify DTC table and DTC switches in the attached dump?

Thanks!

Histeresys is already done (should be there) in the past, that was done while EGR valves where plugged in.
Now I have a need to remove valves completely and while I plug control wires off I've get mentioned dtc errors and MIL light.

disconnect both valves and make few drivings up to working temperature,
than leave it to cool down, than put some ignitions on and off for few times,
check which DTC errors are presented and write that down here.

Hi, there are two errors - P0405 and P140A

here you go,
put hysteresis maps to 0 by yourself.

Thank you ecuedit!
I will study your changes. So you're saying my ecu dump does not contain hysteresis off? Shit. I was told it does.
I'll try to locate maps but obviously without a Damos/mappack for my ECU I will not be able to find them on my own.
Thanks again for your help.
