What is preventing me to read my ECUs?

Here's some info. from QSilver7...

"KL" in bimmerspeak refers to the ignition "terminal" positions. For many, the terms "run" & "accessory" still raises questions...because it doesn't plainly explain which ignition positions they are for those that don't refer to their owners manual for better clarification.

Below is some simple explanation:

• KL 0 = OFF (ignition off position)
• KL R = ignition position 1 ("run" - some electonics & modules are powered up)
• KL 15 = ignition position 2 ("accessory" - all electronics & modules re powered)
• KL 30 = ignition position 3 (where the ignition defauts after starting the engine)
• KL 50 = ignition start position

Note that I mis-spoke in my earlier post about it working better in KL R - I got the labels backwards... it works best in KL 30.

oh i see what you mean.

yea you are right, you are suppose to turn the key to 2nd position, sometimes even, leave the car running (started)
