Component Parts and Harness Connector LocationNIS00272
System DescriptionNIS00273
The rear power seat (LH / RH) retreats when the auto return cancel switch is turned on and each door is
opened.
When the rear power seat switch turned on, or auto return cancel switch is canceled, an auto return is discon-
tinued.
Power is all time supplied

through 50A fusible link [letter F, located in the fuse block (J/B)],

to rear LH seat control unit, rear RH seat control unit terminal 1.
REAR POWER SEAT LH AND RH OPERATION
When rear power seat switch is forward, ground is supplied

to rear seat control unit terminal 10,

through rear power seat switch terminal 2,

through rear power seat switch terminal 3,

through body grounds B5, B40, B131.
When rear seat control unit receives power seat switch forward signal, power is supplied

through rear seat control unit terminal 2,

to rear seat sliding motor terminal 3.

Then ground is supplied

through rear seat sliding motor terminals 5,

through body grounds B5, B40, B131.
When power and ground are supplied, rear power seat slide moves forward.
When rear power seat switch is backward, ground is supplied

to rear seat control unit terminal 15,

through rear power seat switch terminal 1,

through rear power seat switch terminal 3,

through body grounds B5, B40, B131.
When rear seat control unit receives power seat switch backward signal, power is supplied

to rear seat control unit terminal 7,

through rear seat sliding motor terminal 4.
Then ground is supplied

through rear seat sliding motor terminals 5,

through body grounds B5, B40, B131.
When power and ground are supplied, rear power seat slide moves backward.
REAR SEAT RETREAT FUNCTION
When rear door open, ground is supplied

to rear seat control unit terminal 16,

through rear door switch terminal 2,
When rear seat control unit receives automatic return cancel switch ON and rear door switch open signal,
power is supplied

through rear seat control unit terminal 7,

to rear seat sliding motor terminal 4.
Then ground is supplied

through rear seat sliding motor terminals 5,

through body grounds B5, B40, B131.
When power and ground are supplied, rear power seat slide moves backward.
When rear seat sliding motor is operated, ground is supplied

to rear seat control unit terminal 12,

through rear seat sliding motor terminal 1,

through rear seat sliding motor terminal 2,

through rear seat control unit terminal 19,

through rear seat control unit terminals 13,

through body grounds B5, B40, B131.
Then rear seat control unit receives rear power seat sliding sensor signal.
