Wait Detection Switch

  1. The wait detection switch releases the "booming" torque produced in the propeller shaft. After the release of the "booming" torque, the wait detection switch helps provide the 4WD lock gear (clutch drum) shifts. A difference may occur between the operation ("4LO" to "4H" shift only) of the 4WD shift switch and actual drive mode. At this point, the wait detection switch senses an actual drive mode.
  2. The wait detection switch operates as follows:

    4WD lock gear (clutch drum) locked: ON

    4WD lock gear (clutch drum) released: OFF

  3. The wait detection switch senses an actual drive mode and the 4WD shift indicator lamp indicates the vehicle drive mode.
