U0167 RAM Code - Lost Communication With Intrusion Transceiver Control Module
Quick Answer
The vehicle's primary communication network, the Controller Area Network (CAN) data bus system, facilitates information sharing among all connected electronic modules. Common causes include Faulty Intrusion Transceiver Control Module, Intrusion Transceiver Control Module harness is open or shorted, Intrusion Transceiver 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.

Code U0167 RAM Description
Modules communicate via these buses using serial transmission of encoded data messages, where data bits are sent sequentially over a single line. Each module can send and receive data simultaneously, with messages comprised of voltage differentials between two bus circuits. Message integrity is critical; corruption of even a single bit can corrupt the entire message, which includes a Cyclic Redundancy Check (CRC) to ensure accuracy. Faulty messages are identified when they conflict with the CRC, indicating communication failure. Diagnosis with a lab scope might show bus data activity even when actual communication is absent, particularly in high-speed buses prone to opens and terminal push outs.
Open circuits or terminal push outs can isolate modules, disrupting communication. An isolated module can send and receive its own messages but fails to interact with others due to the lack of functional arbitration, altering bus voltage and corrupting ongoing communications. The CAN bus modules connect via a twisted pair of wires, shielding against electromagnetic interference and ensuring the integrity of the low voltage signals. During operation, one wire carries a higher voltage (CAN High) and the other a lower voltage (CAN Low), maintaining balanced signal transmission.
What are the Possible Causes of the DTC U0167 RAM?
- Faulty Intrusion Transceiver Control Module
- Intrusion Transceiver Control Module harness is open or shorted
- Intrusion Transceiver Control Module circuit poor electrical connection
How to Fix the DTC U0167 RAM?
Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
What is the Cost to Diagnose the Code?
Labor: 1.0

Frequently Asked Questions about U0167 RAM Code
What does the OBDII code U0167 mean for my RAM vehicle?
U0167 indicates a "Lost Communication With Intrusion Transceiver Control Module," meaning your vehicle's computer is unable to communicate with the intrusion transceiver, which is responsible for the vehicle's security system.
What are the common symptoms associated with the U0167 code?
Common symptoms may include the vehicle not starting, issues with the key fob (such as inability to unlock/lock doors), and potential warning lights on the dashboard.
What could cause the U0167 code to trigger?
The U0167 code can be triggered by a faulty intrusion transceiver module, damaged wiring or connectors, a dead battery, or issues with the vehicle's Body Control Module (BCM).
How can I diagnose the U0167 code effectively?
To diagnose U0167, use an OBDII scanner to confirm the code, inspect the wiring and connectors for damage, check the intrusion transceiver module for faults, and test the battery voltage.
What steps should I take to repair the U0167 code?
Repair steps include checking and repairing any damaged wiring or connectors, replacing a faulty intrusion transceiver module, or reprogramming the BCM if necessary.
Can I drive my RAM vehicle with the U0167 code?
While you may be able to drive the vehicle, it is not recommended as the vehicle may have security issues, and you could experience starting or locking problems.
How can I prevent the U0167 code from reoccurring?
To prevent recurrence, ensure that all wiring and connectors are intact and free of corrosion, maintain the battery in good condition, and regularly check for software updates for the vehicle's modules.
Is it safe to replace the intrusion transceiver control module myself?
Replacing the intrusion transceiver can be safe if you have the necessary tools and knowledge; however, ensure that you follow the manufacturer's instructions and consider professional assistance if unsure.
What is the cost range for repairing the U0167 code?
Repair costs can vary widely, but if it involves replacing the intrusion transceiver module, it can range from $100 to $500 depending on parts and labor.
