<br />
<br />
* '''''Notes'''''<br />
** If a coding needs to be altered, it has to be converted from decimal (dec) to hexadecimal (hex).<br />
** Bytes are counted from right to left, starting with 0. This is backwards from what you may be used to from editing Long Codings.<br />
** Bits are counted from right to left, starting with 0.<br />
** Once converted to hex each byte has to be converted to decimal seperately.<br />
** Byte 02 coding is the sum of the individual options.<br />
* '''''Example'''''<br />
** Coding is "00217165" (dec) = "03504D" (hex)<br />
** Byte 00 = 4D (hex) = 77 (dec) = Rain Sensor Correction value is 77%<br />
** Byte 01 = 50 (hex) = 80 (dec) = Light Sensor Correction value is 80%<br />
** Byte 02 = 03 (hex) = 03 (dec) = 01+02 = Options 01 (Highway Light) and 02 (Rain Light) set</div>RtWiKiSyS0p
