2 4 Hydraulic Pressure Test
2 4 Hydraulic Pressure Test
Description
Pressure switches are normally off or open (no pressure applied) and read high (+12 volts). When an element is applied, the corresponding pressure switch closes to ground (0 volts) or turns on. The controller tests the OD and 2 4 pressure switches when they are off (when the corresponding friction element is not applied) by briefly applying the OD and 2 4 elements which will cause the corresponding pressure switch to close. The test verifies that the switches are operational and that the switch will close when the corresponding element is applied. If a switch fails to respond, it is retested. If the repeat test also fails, the MIL illuminates and the transmission system defaults to Limpin mode.
