Third Row Power Folding Seat Recliner Calibration

THIRD ROW POWER FOLDING SEAT RECLINER CALIBRATION

NOTE: The power folding seats must both be latched before the recliner calibration routine can be initiated. Failure to do so will result in calibration routine failure.

Any time a third row power folding seat assembly or component is removed, replaced or adjusted, a seat recliner calibration must be performed. This calibration enables the third row power folding seat control module to learn or relearn information (travel limits, resistance to seat travel, etc.) which allows it to perform properly and safely. To perform a seat recliner calibration do the following:

1. Obtain an appropriate scan tool.
2. Connect the scan tool to the vehicle and check for any third row power folding seat system stored trouble codes, correct and erase any stored codes.
3. Ensure that all four seat legs are securely latched to the floor strikers.
4. Using the scan tool, check the latch switch states for both seats. If OK, proceed to 5. If not OK, cycle effected seat to stow and then back to normal. Recheck the latch switch states for both seats. If OK, proceed to 5. If seat fails to latch, diagnose the problem using a scan tool and the appropriate diagnostic service information.
5. Using the scan tool, select the third row power folding seat module menu, Miscellaneous Functions and select the Recliner Calibration Test.
6. Using a scan tool check "routine status" for a pass or fail message. If the calibration routine did not pass, Refer to the appropriate diagnostic information for system diagnosis and repair. Rerun the calibration routine following seat repair procedure.
7. Follow the instructions on the scan tool to complete the test.
8. The third row power folding seat recliner calibration routine is complete.

NOTE: If the third row power folding seat will not complete a full cycle a problem exists with the third row power folding seat system.

In order to obtain conclusive testing of the third row power folding seat system, the Controller Area Network (CAN) data bus, and all of the electronic modules that provide inputs to, or receive outputs from the third row power folding seat system components must be checked. Any diagnosis of the third row power folding seat system should begin with, the use of a scan tool and the appropriate diagnostic service information.
