ESOF Operation PDF

A document that explains the principles of operation for the Electronic Shift on the Fly (ESOF) feature used in four-wheel drive vehicles. It describes how the system allows shifting between 2WD, 4X4 HIGH, and 4X4 LOW, using a control motor on the transfer case managed by several vehicle inputs such as the 4X4 selector switch and brake switch. The pages also include a schematic diagram illustrating the vacuum system used in the ESOF for engaging and disengaging the front hubs.
