less than 1 ampere within 4 to 90 seconds.
(c) Disconnect the leads from terminals.
(d) Approximately 60 seconds later, connect the positive (+)
lead from the battery to terminal 2 (1) and the negative (-)
lead to terminal 1 (2), check that the seat cushion begins
to move backwards.
If operation is not as specified, replace the seat adjuster.
11. INSPECT FRONT VERTICAL 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 counterclockwise.
(b) Reverse the polarity, check that the motor turns clock-
wise.
If operation is not as specified, replace the seat adjuster.
12. INSPECT FRONT VERTICAL MOTOR PTC THERM-
ISTOR OPERATION
( ): Passenger side
(a) Connect the positive (+) lead from the battery to terminal
