SYSTEM SOFT LIMITS
This portion of the system becomes activated when
the control module must shut off a specific seat, re-
cliner or mirror motor because it has reached the end
of its travel. When a mechanical stall condition is de-
tected, the control module will set a soft limit in its
memory and will not allow the motor to be driven
past that point.
To override the soft limits, activate the seat or re-
cliner switch twice in the desired direction holding
the switch activated until the end of travel has been
reached. Reactivate and hold the switch once more
for three seconds. This will cause new soft limits to
be set in the control module.
SETTING SYSTEM SOFT LIMITS
If the control module or motor assemblies have
been replaced, the control module must learn its new
soft limits. To do this, perform the memory seat di-
agnostic self-test. After the tests are completed, the
control module will have learned and memorized its
new soft limits.
TEST PROCEDURES
Before any testing is attempted, the battery should
be carefully charged and all connections and termi-
nals cleaned and tightened to insure proper continu-
ity and grounds.
MEMORY SEAT AND MIRROR DIAGNOSTIC
SELF-TESTS
The system has a built-in set of three self-tests
which check all components in the system while giv-
ing a visual feedback.
To enter the first self-test mode, switch test, press
memory position 1 and 2 buttons, hold for at least
five seconds and no longer than ten seconds. Follow
this immediately by pressing the Set button and hold
for at least five seconds but less than ten seconds.
Three seconds after the button is released, the seat,
recliner and mirrors will move to a mid-travel posi-
tion. Within ten seconds, press and release a seat
button to activate a seat or recliner motor. All
switches except the mirror switches may now be
tested one at a time. The memory switches, Position
1 and 2 and Set buttons, may also be tested. A good
switch contact actuation will NOD the seat. The seat
nod consists of seat front up and seat track forward
followed by seat front down and seat track rearward.
The nod also includes both outside power rear view
mirrors operating in the vertical plane. The system
will continue NODDING for good switches until 10
seconds pass without any switch actuation.
Within 10 seconds of the last seat nod, press mem-
ory position 1 and 2 buttons for at least 5 seconds
