91 200Q 20V Trouble Codes Help

[Russ Southerlin <russell.s.southerlin@lmco.com>]

Subject: 91 200Q 20V.  Question: Is the process for pulling trouble
codes the same as the standard 200Q - as described on Scott Mockery's
web page.  I can pull the codes just fine (I keep getting the 2121, idle
switch code) but I can not seem to get the output tests to work - when I
do the output test (jumper in and then key on) all I get is a 4411 code
which isn't listed as a valid code and when I try to step through them
nothing happens.

Other problem: I want to clear the trouble codes but since the output
tests will not work and I tried pulling fuse #21 and still get trouble
code 2121 - how do you clear them?  I checked the idle switch and it
appears to be functioning O.K. although I need to check the wiring to
the ECU.

TIA
