Dodge 45RFE/545RFE/68RFE Electrical Circuit Tests
Diagnos
tic procedure;
1. Unplug the TCM or Single New Generati on Computer (NGC) with the ignition key off .
2. Jump voltage (always through a fusible link) across the connector pins found in the wire schematic for the vehicle being worked on.
3. Check the return voltage (source voltage) at the pins shown in each diagram.
Note: If necessary the positive meter lead can be moved to the amps jack then with the meter switched to DC amps the same circuits can be checked for load.
The following diagrams are derived from information that has been carefully compiled from industry sources known for their reliability and should be accurate.
Always verify the circuits be tested with factory manuals whenever possible.
Wire colors vary from module to module as well as year to year. Always identify the circuits that are being tested by their connector pin identification.
