ALDL modes

im going to actually go and document all of the aldl modes in $ee

so in $EE i understand the following modes which i understand some other ECMs use:

MODE1: READ DIAGNOSTIC INFORMATION
MODE2: READ 64 BYTE DATA SEGMENT
MODE3: READ BYTES OF ARBITRARY MEMORY (UP TO 84?)
MODE4: TESTING (ACTUATORS, TIMING, FUELING)
MODE5: ENTER PROGRAMMING MODE (ENABLE MODE6)
MODE6: UPLOAD AND EXECUTE PROGRAM SEGMENT
MODE8: DISABLE CHATTER
MODE9: ENABLE CHATTER
MODEA: CLEAR MALF CODES
MODED: SECURITY CHALLENGE/RESPONSE (ENABLE MODE5)

but i can't quite figure out these guys:

MODE7
MODEB
MODEC

anyone have any insight?

MODE 07 is used for module to module communication. For example in the Y array the PCM exchange data with CCM ABS, through this mode.
Most interesting is for traction control there are two system, one is analog, other uses ALDL communication.

MODE 0C is used for writing CALid and VIN to EEPROM tside memory
I have the information available how to do it.
f4 .. 0c 01 [VIN IN HEX-17 bytes]
f4 .. 0c 02 [CAL ID HEX-4 bytes]
I haven`t tested it but it should work like this.

Mode 0b is still undefined. The way it is configured i guess it`s not used in this application.

ah that makes sense, thanks. mode c does seem to work as described!

thanks for that, i wrote vin and cal id# programming into my next tool release. there's no verification, it seems you can program any phrase you want into it as long as it's 16 bytes. my vin is now BLKTRANSAM!
