SeatIMirrorlSteering Column Memory
< The basic features of seaffmirrorlsteering column operation,
including memory positions are integrated into the
ZKE Ill
system. Driver adjustment positions can be memorized and
stored for three different
users.The seat control module is in-
tegral with the seat and mirror switches. The seat control
module stores seat memory position via the "ripple" counter
module.
NOTE-
Passenger seat on sedan models uses a simple control cir-
cuit and do not include a memory module or on-board diag-
nostics.

With the transmission range selector in "P and the mirror
change over switched in the left position, switch the ignition
on and press the
"M" on the memory switch.
Press one of the three position switches
(1, 2 or 3) within
the
7 second memory period (memory indicator lamp will
illuminate for
7 seconds)
- The current positions of the mirrors, seat and steering col-
umn will now be stored in memory.
NOTE- Seat memory is held in an
EEPROM in the seat module and
is stored in memory before the
ZKE goes into its sleep mode.
If the battery is disconnected before the 16 minute sleep
mode activation, seat memorypositions are lost and repro-
gramming is required.
