All Functions Do Not Operate

DIAGNOSTIC PROCEDURE

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 fail to operate?	Go to step 2.	Check the motor which does not operate. < Ref. to SOME MOTORS DO NOT OPERATE , 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 (R200) No. 1 (+) - 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 (R200) No. 1 - Chassis ground:	Is the resistance less than 10 Ω?	Replace the power seat switch assembly.	Check body harness.
