PINPOINT TEST B : The Power Release Seat Does Not Latch to the Floor

B1 CHECK THE INTERIOR DEMAND LIGHTING/BATTERY SAVER OPERATION

Open any of the vehicle doors and check the interior courtesy lamp operation.

Check the electrical operation of the opposite seat release system to verify system voltage is present.

Do the interior lamps illuminate when a door is opened?

Yes	If the opposite seat does not operate from the seat control switch, GO to B3. Otherwise, GO to B2.
No	REFER to Interior Lighting , Symptom Chart to diagnose the inoperative demand lighting/battery saver concern.

B2 CHECK THE SEAT LATCH FEET FOR MANUAL MECHANICAL OPERATION

Inspect both latch feet on the affected seat to make sure neither of the latches are closed and manually release them from the pull strap, if needed.

Make sure the seat release pull strap is not binding and holding the latches in a released state.

Inspect the release cables for kinks or damage causing the cable(s) to bind.

Check the cables and cable mounting for disconnection.

Is a mechanical concern found?

Yes

DISASSEMBLE the seat as necessary to repair the latch(es), cable(s) or release pull strap. TEST the system for normal operation. If the cause is not found, DETACH the power release seat cable from the latch and RETEST the mechanical latch operation. If the latch(es) continue to be inoperative with the cable detached, INSTALL a new latch mechanism or latch foot/feet as needed. REASSEMBLE the seat and TEST for normal operation. If the seat will latch and manually release correctly with the power release seat motor cable disconnected, GO to B3.

GO to B3.
