   Terminals (Wire color)			Condition	Voltage (V) (Approx.)
   Connector	Terminal
   	(+)	(-)
   B152	24 (L/R)	Ground	Sliding switch ON (forward operation)	0
   			Sliding switch OFF	Battery voltage
   	37 (L/P)		Sliding switch ON (backward operation)	0
   			Sliding switch OFF	Battery voltage

OK or NG

1. OK: Sliding switch circuit is OK.
2. NG: GO TO 2.

1. Disconnect driver seat control unit connector and power seat switch (driver side) connector.
2. Check continuity between driver seat control unit connector B152 terminals 24 (L/R), 37 (L/P) and power seat switch connector B154 terminals 24 (L/R), 37 (L/P).

   24 (L/R) - 24 (L/R): Continuity should exist. 

   37 (L/P) - 37 (L/P): Continuity should exist. 

3. Check continuity between driver seat control unit connector B152 terminals 24 (L/R), 37 (L/P) and ground.

   24 (L/R) - Ground: Continuity should not exist. 

   37 (L/P) - Ground: Continuity should not exist. 

OK or NG

1. OK: GO TO 3.
2. NG: Repair or replace harness between driver seat control unit and power seat switch.

Check continuity between driver seat switch as follows.
