How can I diagnose U0057 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for codes and view freeze frame data, which will help you understand the circumstances under which the U0057 code was triggered.
What vehicles are most commonly affected by U0057?
Commonly affected vehicles include the 2011-2019 Ford F-150, 2014-2019 Chevy Silverado, and 2012-2018 Dodge Ram models, often due to electrical system failures.
How can I prevent U0057 from happening again?
Regular inspections of wiring and connections, along with timely software updates from dealerships, can help prevent the recurrence of U0057.
What is U0057?
DTC U0057 indicates a loss of communication with the Body Control Module (BCM), which is critical for various vehicle functions such as lighting, security systems, and interior controls. This code typically arises when there is an interruption in the communication network between the BCM and other modules like the PCM (Powertrain Control Module) or the ABS (Anti-lock Braking System). In practical terms, this can lead to erratic behavior of electrical components, such as non-functioning lights, failure of central locking systems, or even issues with the vehicle starting. Owners of affected vehicles may experience a range of symptoms that can vary in severity. It's important to understand that while this code may not immediately affect the drivability of the vehicle, it can lead to more serious electrical issues if left unresolved. Addressing DTC U0057 promptly ensures that all electrical systems function correctly, enhancing both safety and convenience while driving.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0057 is present:
- Check engine light stays on constantly, indicating a potential electrical issue that needs attention.
- Interior lights may malfunction, flickering or failing to turn on when the doors open, which can be frustrating for drivers.
- Central locking system may become inoperative, preventing doors from locking or unlocking properly.
- Dashboard warning lights might illuminate erratically, leading to confusion about the vehicle's actual status.
- Vehicle may experience intermittent starting issues, making it unreliable for daily use.
Possible Causes
Most common causes of U0057 (ordered by frequency):
- The most common cause of U0057 is damaged wiring or connectors in the communication network, which occurs in about 60% of cases due to wear and corrosion.
- Another frequent cause is software issues or glitches in the BCM, which can lead to communication failures, particularly after updates or repairs.
- Faulty modules, such as a malfunctioning PCM or ABS module, can also trigger this code; ensuring all modules are functioning correctly is essential.
- Less common causes include electrical shorts or ground issues, which may not be immediately visible but can disrupt communication.
- Rarely, environmental factors, such as water ingress from leaks, can damage the BCM and lead to U0057.

Diagnostic Steps
Professional U0057 Diagnosis Process
Follow these systematic steps to accurately diagnose U0057. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Perform a visual inspection to look for damaged wiring, loose connections, or corrosion in the BCM wiring harness (5-10 minutes)
Step 1: Perform a visual inspection to look for damaged wiring, loose connections, or corrosion in the BCM wiring harness (5-10 minutes).
Step 2: Step 2: Use the GeekOBD APP to scan the vehicle for all diagnostic trouble codes, including freeze frame data that can provide context for the fault (10-15 minutes)
Step 2: Use the GeekOBD APP to scan the vehicle for all diagnostic trouble codes, including freeze frame data that can provide context for the fault (10-15 minutes).
Step 3: Step 3: Test components using a multimeter to verify proper voltage and ground at the BCM and related modules (20-30 minutes)
Step 3: Test components using a multimeter to verify proper voltage and ground at the BCM and related modules (20-30 minutes).
Step 4: Step 4: Conduct a system function test to ensure all systems are operating correctly after any repairs and clear the codes (10-15 minutes)
Step 4: Conduct a system function test to ensure all systems are operating correctly after any repairs and clear the codes (10-15 minutes).
Step 5: Step 5: Perform a road test under various conditions to ensure that the communication issue has been resolved and the vehicle operates normally (15-20 minutes)
