NOTE:

To initiate a chime code sequence cycle, turn the ignition switch ON and OFF 3 times within 5 seconds.  The

first digit will chime, then a pause, followed by the second digit.  For example, a code 13 will have 1 chime, fol-

lowed by a pause, and then 3 chimes.  The third row power folding seat control unit will clear all codes that

have been corrected after 255 ignition cycles.
