    Ok - I've been searching, but I can't seem to find any details on how to change the headlight timeout (after turning off ignition and opening door) from the default of 30 seconds to 0 seconds. I've found lots of references to the ability to change it, but nothing on how.

    Anybody have any ideas?

    I imagine it can be done the same way that we can turn off the backup and seatbelt beeps with Putty and an ODBII adapter. I just don't know the necessary commands.

    Or, maybe there is another way. ?

    Thanks

    I believe that dealer has to do that with tech-stream, or someone with laptop/software to do it. ODBII won't cut it.

    I believe Spiderman is correct......in the 10-11 it has to be done via tech stream.

    Oh - there's got to be a way.

    Techstream ( I imagine ) and the Laptop/OBDII process just changes register values in the ECU.
    Hmmm - "How to figure out which register and which value to use"....

    Found some people talking about this relative to ScanGauge II and how it doesn't support the CAN 5-Byte protocol.
    Looks like a different protocol than the (apparent) CAN 11-bit I was using to change the backup and seatbelt beeps.

    Toyota Specific : Linear Logic : Home of the ScanGauge


    Rats!

    Still looking for ideas.
