When Monitored
WARNING: This page is about a different car, the 2019 RAM 3500 HD. However, it is still accessible from the selected car via links, so may be relevant.
This diagnostic runs continuously when the following conditions are met:
- Common Monitoring Conditions:
- The TCM supply voltage is between 10.0 and 16.0 volts.
- Ignition switch Run position signal is detected via dedicated circuit to TCM.
- Engine speed (CAN Message) is greater than 550 RPM.
- There are no ignition switch failures.
- No Output Speed Sensor errors are detected.
- No Transmission Sump Temperature electrical failures.
- No CAN bus failures.
- Condition One, Stuck In Range:
- Ignition switch is in the run position for greater than 5 seconds.
- Start up transmission oil temperature is between -50° C and 40° C (-58° F and 104° F).
- Engine coolant temperature data (CAN) is normal and greater than or equal to 70° C (158° F).
- Engine coolant temperature increase is greater than 50° C (90° F).
- Output speed sensor greater than 300 RPM for a calibrated amount of time.
- Condition Two, Maximum Gradient:
- Transmission Sump Temperature is less than 150° C (302° F)
- Output speed sensor greater than 300 RPM for a calibrated amount of time.
- Condition Three, Three Sensor Compare:
- Ignition in the run position for greater than 5 seconds.
- Engine coolant temperature data (CAN) is normal and greater than or equal to 70° C (158° F).
- Torque Converter Fluid temperature is greater than 60° C (140° F).
