DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK OTHER COMMUNICATION. Perform communication with the system other than the power seat control module using the Subaru Select Monitor.	Is the communication to other control module possible?	Go to step 2 .	Perform the "Communication for Initializing Impossible" of LAN system. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >
2 CHECK LAN SYSTEM. Perform the inspection for LAN system. < Ref. to PROCEDURE , Basic Diagnostic Procedure. >	Is there any fault?	Perform the diagnosis according to the inspection for LAN system.	Go to step 3 .
3 CHECK FOR POOR CONTACT. Turn the ignition switch to OFF. Disconnect the connector of power seat control module. Disconnect the connector of body integrated unit. Connect the disconnected connectors. Turn the ignition switch to ON. Perform communication with the power seat control module using the Subaru Select Monitor.	Is communication possible?	The circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector, temporary open or short circuit of harness may be the cause.	Replace the power seat control module. < Ref. to POWER SEAT CONTROL MODULE (SEAT WITH MEMORY FUNCTION) , REMOVAL, Power Seat System. >
