CHANGEOVER SWITCH: Diagnosis Procedure

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

1. CHECK CHANGEOVER SWITCH SIGNAL
   1. Turn ignition switch ON.
   2. Check voltage between automatic drive positioner control unit connector and ground.

      Terminals			Change over switch condition	Voltage (V) (Approx.)
      (+)		(-)
      Automatic drive positioner control unit connector	Terminal
      M33	2	Ground	RIGHT	0
      			Other than above	5
      	18		LEFT	0
      			Other than above	5
