NOTE:

Check electrical and electronic components and wires before removing seat further to avoid unnecessary repair costs.

-- Perform the following tests:

Check the fuse. Refer to appropriate SYSTEM WIRING DIAGRAM
Check the voltage at the connector station and perform fault finding if necessary. Refer to appropriate SYSTEM WIRING DIAGRAM
Check the voltage to the control module. Refer to appropriate SYSTEM WIRING DIAGRAM Wiring Diagram.
Check the voltage to the Seat Forward/Back Adjustment Motor -V288-. Refer to appropriate SYSTEM WIRING DIAGRAM Wiring Diagram.

-- If fuse is faulty: replace fuse. Refer to appropriate SYSTEM WIRING DIAGRAM.Wiring Diagram.

-- If voltage to connector station is low: Repair or replace the wire. Refer to appropriate SYSTEM WIRING DIAGRAM
