10. INSPECT RECLINING MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (±) lead to terminal 2, check that the
motor turns clockwise.
(b) Reverse the polarity, check that the motor turns counter-
clockwise.
If operation is not as specified, replace the seat adjuster.
11. INSPECT RECLINING MOTOR PTC THERMISTOR OP-
ERATION
(a) Connect the positive (+) lead from the battery to terminal
2, the positive (+) lead from the ammeter to terminal 1 and
the negative (±) lead to the battery negative (±) terminal,
then recline the seat back to the most forward position.
(b) Continue to apply voltage, check that the current changes
to less than 1 ampere within 4 to 90 seconds.
(c) Disconnect the leads from the terminals.
(d) Approximately 60 seconds later, connect the positive (+)
lead from the battery to terminal 1 and the negative (±)
lead to terminal 2, check that the seat back begins to fall
backward.
If operation is not as specified, replace the seat adjuster.
12. INSPECT LUMBAR SUPPORT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (±) lead to terminal 2, check that the
lumbar support moves to release side.
(b) Reverse the polarity, check that the lumbar support
moves forward.
If operation is not as specified, replace the seat adjuster.

13. INSPECT LUMBAR SUPPORT MOTOR PTC THERM-
ISTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (±) lead to terminal 1 on the lumbar
support motor connector and move the lumbar support to
front end position.
(b) Continue to apply voltage, check that a circuit breaker op-
eration noise can be heard within 4 to 60 seconds.
(c) Reverse the polarity, check that the lumbar support be-
gins to move to release side within approximately 60 se-
conds.
If operation is not as specified, replace the motor.
