    Right everything depends on os and transmission and brake switch. Different pins need grounding depending on if it is a manual or auto.He is probably thinking parking brake and not the footbrake. He also needs to know what his setup is regarding c1 32 and c1 34

    He may be running a manual trans file.

    Also we are talking foot brake and not park brake correct? There is no input for the parking brake is there? That is what they were talking about a few posts up

    Yes sir ... you are correct ... PCM does not monitor the parking brake (emergency brake). PCM does monitor the "foot brake" pedal switch in both auto & manual trans OS, and clutch pedal switch in manual OS.

    02020003 os, it is a th-400 car, the tune is from a 4l60 car with the trans stuff shut off. the tcc is not hooked up, the P/N wire is grounded.

    when i try the case, it tells me "no reply"

    That is a COS ... what was the original OS the COS is based on ? What year and model vehicle was the original OS from ?

    Camaros use a very simple P/N switch ... trucks use a more complex switch. Also, brake pedal switch input pin varies by OS / application.

    Your pcm may be looking for a clutch pedal switch

    That OS / vehicle uses a simple P/N switch ... grounding PCM C1 (Blue) pin 34 (orange / black wire) will indicate Park / Neutral to the PCM.

    The brake input (12 volt 10 amp circuit - described previously) for that OS is PCM C1 pin 33 (purple wire). The tune was from an A4 - so no clutch switch input is required.

    With these PCM inputs properly configured, no relevant DTCs stored in the PCM, the CKP learn routine should run.
