EXCERPT:
Removal and Installation
I When removing or installing the seat trim, carefully handle it to keep dirt out and avoid damage.
H For Wiring Diagram, refer to EL-251, “POWER SEAT” for details.
CAUTION:
I Before removing the front seat, turn the ignition switch off, disconnect both battery cables and wait at least 3 minutes.
I When checking the power seat circuit for continuity using a circuit tester, do not confuse its connector with the side air bag module connector. Such an error may cause the air bag to deploy.
I Do not drop, tilt, or bump the side air bag module installed in the seat. Always handle it with care.
Front seatback finisher
1. When removing, first disconnect clips C101 located on front seatback finisher lower side.
2. Lift up front seatback finisher lower part and remove upper hooks.
I Install in the reverse order of removal.
