__FORCETOC__
== Coding ==

* '''Byte 00''': ''Rain Sensor Correction (Infrared Transperency at 880nm)''
* '''Byte 01''': ''Light Sensor Correction (Transperency)''
* '''Byte 02''': ''Options''
** +1 = Highway Light
** +2 = Rain Light
** +4 = Rain Closing


* '''''Notes'''''
** If a coding needs to be altered, it has to be converted from decimal (dec) to hexadecimal (hex).
** Bytes are counted from right to left, starting with 0.   This is backwards from what you may be used to from editing Long Codings.
** Bits are counted from right to left, starting with 0.
** Once converted to hex each byte has to be converted to decimal seperately.
** Byte 02 coding is the sum of the individual options.
* '''''Example'''''
** Coding is "00217165" (dec) = "03504D" (hex)
** Byte 00 = 4D (hex) = 77 (dec) = Rain Sensor Correction value is 77%
** Byte 01 = 50 (hex) = 80 (dec) = Light Sensor Correction value is 80%
** Byte 02 = 03 (hex) = 03 (dec) = 01+02 = Options 01 (Highway Light) and 02 (Rain Light) set
