DTC B1849 Dodge

Description

The Transmission Control System tests the pressure switches when they are off. The test verifies the switches are operational (Close with pressure applied). The Transmission Control System verifies the switch closes when the corresponding element is applied. If a switch fails to close, it is re-tested. If it fails the second test, the DTC will set, the MIL will illuminate and the transmission system will default to the orderly Shutdown routine.
