U1450 Jeep Code - Implausible DTCM Torque Message Received
Quick Answer
The messages sent on the Controller Area Network (CAN) bus are distinguished by an Identifier (ID). Common causes include Faulty Drive Train Control Module (DTCM), Drive Train Control Module harness is open or shorted, Drive Train Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Frequently Asked Questions about U1450 Jeep Code
1. What does the OBDII code U1450 mean on a Jeep?
U1450 indicates that the vehicle's Diagnostic Trouble Code Module (DTCM) received an implausible torque message, often due to communication issues among control modules.
2. What are the common symptoms of code U1450 in a Jeep?
Symptoms may include the check engine light turning on, reduced engine performance, erratic shifting, or activation of limp mode.
3. What causes the U1450 code to appear on a Jeep?
Common causes include faulty wiring or connectors, a malfunctioning DTCM, damaged CAN bus communication lines, or issues with other related control modules.
4. Can a bad battery cause the U1450 code on a Jeep?
Yes, a weak or failing battery can cause voltage fluctuations, potentially disrupting module communication and triggering the U1450 code.
5. How is code U1450 diagnosed in a Jeep?
Diagnosis involves scanning the vehicle with an OBDII tool, inspecting wiring and connectors, checking the CAN bus network for continuity, and testing the affected control modules.
6. Is it safe to drive a Jeep with the U1450 code?
Driving with code U1450 may not be safe, as it can affect torque management, potentially leading to reduced performance or unexpected behavior. It’s best to address the issue promptly.
7. How do you fix the U1450 code on a Jeep?
Repairs may involve fixing or replacing damaged wiring, repairing CAN bus communication issues, reprogramming the DTCM, or replacing a faulty module if necessary.

Codes U0414-00 U1450-00
The transfer case module also known as the final drive control module controls front to back torque but also sends a message to the ELSD module the message is sent in bits ID if any of the bits doesn’t get through (bad wire contacts) it will then become an implausible message the ELSD will default to 0lb torque and relay this message on to the ELSD Motor the motor will confirm that it has received this message back to the ELSD module and the electronic limited slip diff module passes the information to the transfer case module which then becomes an implausible message because it is 0 lb and not the (80 lb ). that was the requested torque in this instance, it’s allowed about 20% difference this is to allow for wear in the motor so now you have two faults but are from the same source.
Hope this has helped.
i’ve cleaned the Contacts on both of the modules and will report back after I’ve done several miles
I used a scan tool to graph the requested and actual torque. See photo
