Schematic Reference: Power Seats Schematics

DEFINITION: This test is used by the technician to aid in the diagnosis of the recline function of the seat being inoperative. The test diagnoses the seat adjustment switch and the motor circuits.

Did you perform the Diagnostic System Check-Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle

1. With the ignition OFF, disconnect connector C2 from the seat module.
2. Use an ohm meter to test the seat entry position switch status. The switch should be normally open.

Does the meter indicate the switch to be normally open?

Go to Step 3

Go to Step 17

1. Remove the seat adjustment switch from the seat. Refer to Power Seat Switch Replacement .
2. Test the seat adjustment switch. Refer to the Diagnostic Aids above.

Does the seat switch test good?

Go to Step 4
