Ok on the weekend I managed to some more testing and have found this.
Test 1.Pid TBASEPAT code changes from 11 to 9 in with hot state tuned out. No converter lock out during test
Test 2.Pid TBASEPAT code changed from 9 to 4 when at normal driving the converter unlocks for no apparrent reasonand dropped back to third.
Unfortunatley I didnt have TFT and VSS pids loaded.
Logged TCCE,TCCEP,TCCES,TCCEO. They all changed at the same time as the converter unlocked.
TCCE went from unknown to CMD off only fo 3.45secs and went back to unknown.
TCCES,TCCEP and TCCEO all went from unknown to failed back to unknown over the same 3.45 sec periord.
All mills were turned on but didnt throw any codes.
If anybody out there has any idea it would be great.
Cheers Ian
