Unveiling U1343: Common Symptoms You Shouldn’t Ignore
If you notice the Engine Light ON (or Service Engine Soon Warning Light), it could be due to the u1343 fault code.
Here are the symptoms to look out for:
- The U1343 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
- Other symptoms may include issues with the vehicle’s transmission, such as difficulty shifting gears or the transmission slipping.
- The vehicle may also experience a decrease in power or acceleration, and the engine may stall or misfire.
- Additionally, the vehicle’s fuel efficiency may decrease, and there may be issues with the vehicle’s braking system.
Decoding U1343: Common Causes Of The Fault Code
The automobile fault code U1343 can be caused by a faulty control module, open or shorted harness, or poor electrical connection.
- The automobile fault code U1343 can be caused by a faulty control module that sets the diagnostic trouble code (DTC).
- It can also be caused by an open or shorted control module harness.
- Additionally, a poor electrical connection in the control module circuit can also trigger this fault code.
- These are the three main causes of the U1343 fault code in automobiles.

Crunching The Numbers: U1343 Repair Cost & Complexity
The automobile fault code U1343 can be diagnosed and fixed within an estimated repair time of 1.0 hour. The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour.
Therefore, the total cost of diagnosis and fixing the U1343 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.
Decoding U1343: Understanding Your Car’s Abs System Fault
The U1343 fault code is related to the Local Interconnect Network (LIN) Bus in a vehicle. The LIN Bus is a single wire that transmits data at a rate of 10.417 Kbits between a master control module and other LIN devices within a subsystem.
If the serial data communication is lost between any of the LIN devices on the LIN bus network, the master control module will set a no communication code against the non-communicating LIN device. The U1343 code specifically refers to a fault in the Chassis Control Module LIN Bus. This fault code sets when a supervised periodic message that includes the transmitter device availability has not been received.
