   Connector	Terminals (Wire color)		Reclining switch condition	Voltage (V) (Approx.)
   	(+)	(-)
   B152	25 (L/OR)	Ground	FORWARD	0
   			Other than above	Battery voltage
   	38 (LG/B)		BACKWARD	0
   			Other than above	Battery voltage

   OK or NG 

   OK: Reclining switch circuit is OK.

   NG: GO TO 2.

2. CHECK HARNESS CONTINUITY 
   1. Disconnect driver seat control unit connector and power seat switch connector.
   2. Check continuity between driver seat control unit connector B152 terminals 25, 38 and power seat switch connector B175 terminals 25, 38.

      25 (L/OR) - 25 (L/OR) : Continuity should exist. 

      38 (LG/B) - 38 (LG/B) : Continuity should exist. 

   3. Check continuity between driver seat control unit connector B152 terminals 25, 38 and ground.

      25 (LO/R) - Ground : Continuity should not exist. 

      38 (LG/B) - Ground : Continuity should not exist.

   OK or NG 

   OK: GO TO 3.

   NG: Repair or replace harness between driver seat control unit and power seat switch.

3. CHECK RECLINING SWITCH
