4X4 Low (4X4L) Switch

DESCRIPTION
The 4x4 Low (4x4L) range switch is located on the transfer case cover. It provides an indication of when the 4x4 transfer case gear system is in the low range. The PCM then modifies shift schedule for 4x4L operation.

SYMPTOMS
Failed ON - early shift schedule in 4x2 and 4x4H.
Failed OFF - shifts delayed in 4x4L.
If the 4x4 low indicator light fuse is blown, the transmission will shift according to 4x4 low shift schedule regardless of transfer case position.
