Scheme 282: Driver's Seat

Scheme 283

Remove the driver's seat (see «FRONT SEAT REMOVAL/INSTALLATION»(/acura/zdx/i-2009-2013/remont/seats/#seats__front-seat-removalinstallation) ).
Remove the seat-back panel (see «FRONT SEAT-BACK COVER REPLACEMENT»(/acura/zdx/i-2009-2013/remont/seats/#seats__front-seat-back-cover-replacement) ).
Disconnect connector A (3P) and connector B (2P) from the seat heaters.
Check for continuity between seat heater connector A (3P) terminal No. 3, and seat heater connector B (2P) terminal No. 2. There should be continuity.
If there is no continuity, replace the seat wire harness.
Check for continuity between seat heater connector B (2P) terminals No. 1 and No. 2. There should be continuity.
If there is no continuity, replace the seat-back heater (see «SEAT HEATER REPLACEMENT»(/acura/zdx/i-2009-2013/remont/seats/#seat-heaters) ).
Check for continuity between seat heater connector A (3P) terminals No. 1 and No. 3, and terminals No. 2 and No. 3. There should be continuity.
If there is no continuity, replace the seat cushion heater (see «FRONT SEAT CUSHION HEATER»(/acura/zdx/i-2009-2013/remont/seats/#seat-heaters__front-seat-cushion-heater) ).

Front Passenger's Seat

Scheme 284

Scheme 284: Front Passenger's Seat

Remove the front passenger's seat (see «FRONT SEAT REMOVAL/INSTALLATION»(/acura/zdx/i-2009-2013/remont/seats/#seats__front-seat-removalinstallation) ).
Disconnect the 4P connector from the seat heater.
Check for continuity between seat heater 4P connector terminals No. 1 and No. 3 and terminals No. 2 and No. 3. There should be continuity.
If there is no continuity, replace the seat cushion heater (see «FRONT SEAT CUSHION HEATER»(/acura/zdx/i-2009-2013/remont/seats/#seat-heaters__front-seat-cushion-heater) ).

Scheme 285

Scheme 285: Rear Seat

Remove the rear seat cushion (see «REAR SEAT REMOVAL/INSTALLATION»(/acura/zdx/i-2009-2013/remont/seats/#seats) ).
Disconnect the 3P connectors (A) from the seat cushion heater.
Check for continuity between seat cushion heater 3P connector terminals No. 1 and No. 2 and terminals No. 2 and No. 3. There should be continuity.
If there is no continuity, replace the seat cushion heater (see «REAR SEAT CUSHION HEATER»(/acura/zdx/i-2009-2013/remont/seats/#seat-heaters) ).

Scheme 286

Scheme 287

Remove the center console panel (see «CENTER CONSOLE PANEL REMOVAL/INSTALLATION»(/acura/zdx/i-2009-2013/remont/gauges-instrument-panels/#consoles__center-console-panel-removalinstallation) ).
Remove the two screws, and the seat heater switch from the panel.
Check for continuity between the terminals in each switch position according to the table. NOTE: Make sure the correct test lead (+ or -) is placed on the terminal. When checking for continuity across the diode, use the diode setting (-->-)on the digital volt/ohm meter to check the diode bias. Note this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).
If the continuity is not as specified, replace the switch.
Install the parts in the reverse order of removal.

Remove the two screws, and the seat heater switch from the trim.
Check for continuity between the terminals in each switch position according to the table. NOTE: Make sure the correct test lead (+ or -) is placed on the terminal. When checking for continuity across the diode, use the diode setting (-->-) on the digital volt/ohm meter to check the diode bias. Note this important operating characteristic; diode bias causes a diode to fully conduct electricity in one direction (forward), while not at all in the opposite direction (reverse).
