4x4 Low Range Switch

The 4x4 low range switch is located on transfer case cover. The 4x4 low range switch provides Powertrain Control Module (PCM) with an indication of 4WD low range. PCM modifies shift schedule with output signals to transmission Electronic Pressure Control (EPC) solenoid. Early shifts will occur if switch fails in ON position. Delayed shifts will occur if switch fails in OFF position.
