Pasted from SCWC list
-----------------------------------------------------
I farted around with the throttle body last night. Let's just say
I'm not ever going to screw with the ETS ever again! I got myself
stuck in LHM. Turn key on, TCS CTRL light stays on, start, barely
idles... grrrrrr... figured pulling the battery cables overnight
might help... nope! So I had the pleasure of driving around in LHM -
I figure it's probably much easier to drive a manual tranny in LHM
than an auto since you can downshift and heel-toe and all sorts of
tricks to keep the stupid thing running... I had to pick up a couple
of servers in Burnaby this morning, which wasn't too bad, mostly
highway. Let it be known that LHM does indeed work at highway
speeds - it juts takes longer to get there. I called around and the
only place that could accomodate me today was Bob... so I limped over
to Swedish Auto (one of the most interesting driving experiences I
have *EVER* had, driving in traffic on Georgia st. in LHM!), Bob,
with *much* persuasion, and certainly not before informing me I would
need at least $2000 in parts to get me out of LHM (he sounds like a
real big fan of TCS/ETS... "That ETS was a real piece of
shit", he said), cleared all the codes. That got me out of LHM. He
guaranteed me I'd be back in LHM the moment I left the shop. Right.
The TechII is a really cool device! Our cars are ludicrously
complex... there are so many different computers that each throw up
codes, then confuse each other, and throw up more codes. The first
thing Bob did was clear the codes in the "DTM" computer - this seems
to be the "main" one. Intermittent throttle position sensor fault
was the code. Cleared that, tried to start, no go - still LHM, and
the TPS fault code was back right away. Then, after him telling me I
was hosed, I urged him to reset the codes in the ETS system - that
got me out of LHM, then I had him reset the DTM code again to get rid
of the TPS fault code. Started up, no problems. No more codes.
It's funny how one had to be cleared to get the other one to settle
down.
I went and did about 10 adaptation runs up Cypress, and the car is
running better than ever! For whatever reason, it feels like the
turbo spools up even faster now.
It seems there are two different types of ETS codes that can cause
LHM - intermittent and permanent. Each time you turn the key on, the
ETS does a very basic test. From what I can tell, if a permanent
code gets stored, the test will see the permanent code and will not
allow electronic operation of the throttle. On the other hand, if
there is an intermittent code stored, it'll allow electronic
operation until the fault occours again - then it'll LHM until the
key is cycled off and on, and the cycle repeats.
Overall quite a learning experience, and it only cost me about $40 to
have all the e-cobwebs swept away. Clean slate once more...
