3.2.148 DTC reading and erasing

[DH Individual]

Hi Guys,

i ran into something i yet was not able to figure out if it's a bug in the VCM Scanner or really in the ECM:

Yet had this in GM E38 and different DCX ECMs.

When reading out DTCs and afterwards erasing them it nearly always happens, that the formerly shown codes still appear as permanent DTC although those are definatly gone.
F.E. a ETC Sensor Circuit high caused by an unplugged sensor. Plug it in, erase the code, code still shown.

When reading with a different tool as OEM Tools, SCT, Diablo or whats actually handy, there are no codes shown.

Anyone else yet ran into this?

Thanks

Flo

VCM Scanner shows things that a lot of regular scanners don't display.

Permanent codes can't be "cleared", that's the whole point of them...

This isn't really an issue, Scanner is just giving you more info
