All Functions Do Not Operate (Without Memory)

Step	Check	Yes	No
1 CHECK SEAT FUNCTIONS. Operate each power seat switch and check that each power seat function operates normally.	Does all function fails to operate?	Go to step 2 .	Check the motor which does not operate. < Ref. to SOME MOTORS DO NOT OPERATE (WITHOUT MEMORY) , INSPECTION, Power Seat System. >
2 CHECK FUSE. Check the power seat fuse inside the fuse box.	Is the fuse blown out?	Replace the appropriate fuse.	Go to step 3 .
3 CHECK POWER SUPPLY CIRCUIT. Disconnect the connector of power seat switch assembly. Measure the voltage between harness connector and chassis ground. Connector & terminal Driver's seat (R369) No. 7 (+) - Chassis ground (-): Passenger's seat (R190) No. 7 (+) - Chassis ground (-):	Is the voltage 10 V or more?	Go to step 4 .	Check body harness.
4 CHECK POWER SUPPLY CIRCUIT. Measure the resistance between power seat switch harness connector and chassis ground. Connector & terminal Driver's seat (R369) No. 8 - Chassis ground: Passenger's seat (R190) No. 8 - Chassis ground:	Is the resistance less than 10 Ω?	Replace the power seat switch assembly.	Check body harness.
