Step
Check
Yes
No
1
CHECK SWITCH.
1) Disconnect the harness connector of mem-
ory switch assembly.
2) Check memory switch. <Ref. to SE-28,
CHECK MEMORY SWITCH (MEMORY-
EQUIPPED), INSPECTION, Power Seat Sys-
tem.>
Is there any problem on the
inspection result?
Go to step 2.
Replace the mem-
ory switch assem-
bly.
2

Measure the resistance between the memory
switch connector and memory module connec-
tor.

harness.
3
CHECK COMBINATION METER.
Turn the ignition switch to ON and check the
indicator inside the meter while the selector
lever is in P position.

Go to step 4.
Check the combi-
nation meter. <Ref.
to IDI-5, INSPEC-
TION, Combina-
tion Meter
System.>

10.FAILS TO PERFORM THE REPLAY OPERATION (DRIVER’S SEAT, WITH MEMORY)
Step
Check
Yes
No
1
CHECK MEMORY FUNCTION.
Perform the memory operation of the seat posi-
tion, and check the memory replay operation.
Does the seat position memory
replay correctly?
Memory function is
normal. Memory
seems to be
cleared since volt-
age was less from
the operation-
ensured voltage
temporary at the
time of memory
restoring and man-
ual operation. It
operates normally
by registering a
memory.
Go to step 2.
2
CHECK MEMORY FUNCTION.
At the step 1 memory operation, check the beep
sound (once).
Check the beep sound?
Go to step 3.

ory switch assembly.
2) Check memory switch. <Ref. to SE-28,
CHECK MEMORY SWITCH (MEMORY-
EQUIPPED), INSPECTION, Power Seat Sys-
tem.>
Is there any problem on the
inspection result?
Go to step 4.
Replace the mem-
ory switch assem-
bly.
4
CHECK HARNESS.
Measure the resistance between the memory
switch connector and memory module connec-
tor.
Connector & terminal

(R195) No. 14 — (R198) No. 2:
(R195) No. 15 — (R198) No. 8:
Is the resistance less than 10
:? Go to step 5.
Check power seat
harness.
5
CHECK COMBINATION METER.
Turn the ignition switch to ON and check the
indicator light inside the meter.
• AT model: when the select lever is in “P” posi-
tion
• MT model: when the parking brake lever is
pulled
Is indicator light displayed?
Go to step 6.
Check the combi-
nation meter. <Ref.
to IDI-5, INSPEC-
TION, Combina-
tion Meter
System.>
6
CHECK OPERATION.
Check the rotation of each motor when perform-
ing all the power seat switch operation.
Does each motor rotate for one
second or more when operating
each switch?
Replace the mem-
ory module.
Encoder defec-
tion. Replace the
appropriate motor.

ory module.
Replace the power
seat switch assem-
bly.
Step
Check
Yes
No
1
CHECK SEAT FUNCTION.
Operate each power seat switch and check that
each power seat function operates normally.
Does all function fails to oper-
ate?
Go to step 2.
Check the motor
which does not
operate. <Ref. to
SE-39, SOME OF
THE MOTORS DO
NOT OPERATE
