Diagnosis Procedure

Regarding Wiring Diagram information, refer to "WIRING DIAGRAM ".

1. CHECK RECLINING MOTOR LH POWER SUPPLY 
   1. Turn the ignition switch OFF.
   2. Perform "Active test" ("SEAT RECLINING") with CONSULT
   3. Check voltage between driver seat control unit harness connector and ground.

      Terminal			Test Item		Voltage (V) (Approx.)
      (+)		(-)
      Driver seat control unit connector	Terminal
      B203	36	Ground	SEAT RECLINING	OFF	0
      				FR (forward)	Battery voltage
      				RR (backward)	0
      	44			OFF	0
      				FR (forward)	0
      				RR (backward)	Battery voltage

      Is the inspection result normal? 

      YES: Replace reclining motor LH. (Built in seatback assembly). Refer to "DISASSEMBLY AND ASSEMBLY ".

      NO: GO TO 2

2. CHECK RECLINING MOTOR LH CIRCUIT 
   1. Disconnect driver seat control unit connector and reclining motor LH.
   2. Check continuity between driver seat control unit harness connector and reclining motor harness connector.
