FRONT POWER SEAT CONTROL SYSTEM (w/ Memory) - Wireless Transmitter Memory Function does not Operate


DESCRIPTION

With the ignition switch ON, press the manual door control switch LOCK or UNLOCK while holding a seat memory switch (M1 switch or M2 switch). Doing so registers the transmitter recognition code into the seat memory switch that was pressed. After registration is completed, the answer-back buzzer sounds.
