Diagnostic Overview

The Seat Backrest will not Fold Down, Fold Upright - 40 Percent, Manual Release

Normal Operation and Fault Conditions

Pulling the seat recliner handle releases the backrest for recline positions and to fold down. When the backrest is folded fully down, pulling the recliner handle again to the second stop position releases the seat latch feet from the strikers for the E-Z entry position. The inboard and outboard recliners are synchronized and both lock the backrest when upright. When folding the backrest down, the outboard recliner is released directly by the recliner lever while the inboard recliner is released by a cable attached to the outboard recliner. If the backrest is not folded all the way down, the seat does not release to the E-Z entry position.

The seat recliner contains a safety mechanism to prevent the backrest from being raised upright until the seat latches are latched to the strikers on the floor. When the backrest is folded down, the safety mechanism is engaged by the cable attached to the inboard latch foot and outboard recliner. The safety mechanism is disengaged when the seat latch feet are completely locked around the strikers, which then allows the backrest to be raised upright.

Pinpoint Test

1. CHECK THE OUTBOARD RECLINER AND CABLES FOR DAMAGE

1. Remove the outboard recliner outer cover and check for foreign objects, disconnected or damaged cables or obvious damage to the outboard recliner.

2. Pull the release strap and check the outboard recliner operation.

- The release lever should move smoothly in both directions without binding and return to the rest position with light spring tension.
- With the strap pulled, the backrest should move forward and rearward in all the recline positions.
- With the backrest fully upright, release strap pulled fully rearward and with forward pressure applied to the backrest, the backrest should move slightly forward beyond the stopping point.

Is there any foreign object, disconnected or damaged cables or obvious damage to the outboard recliner found?








2. CHECK THE RECLINER HANDLE POSITION

1. Check if the recline handle is pointing downward instead of forward as compared to the handle position of the 60 percent seat.

Is the recline handle pointing downward?
