Transfer Case Interlock

The transfer case interlock safety feature is designed to prevent transfer case shifter from being shifted out of "H" or "L" unless vehicle's gear selector is in neutral position.

When gear selector is placed in neutral position, voltage is allied to Interlock Relay 2's coil through Transmission Range Selector Switch (Z110). The relay's coil is grounded through Park/Neutral Position Switch (X167). Interlock Relay 2 now energizes and applies voltage from Fuse E1 to Transfer Box Solenoid. When Transfer Box Solenoid is energized transfer Box shifter can be operated.
