What vehicles are most commonly affected by C0D43?
C0D43 is often seen in vehicles like the 2015-2018 Ford F-150, 2016 Chevrolet Malibu, and 2017 Dodge Charger, particularly those with electrical system issues.
How can I prevent C0D43 from happening again?
To prevent C0D43, regularly inspect electrical connections for corrosion, maintain your battery, and keep the BCM dry and protected from moisture.
What is C0D43?
The DTC C0D43 is a generic diagnostic trouble code that typically indicates an issue with the vehicle's body control module (BCM) or a related circuit. This code can manifest in various vehicle makes and models, particularly in recent models from manufacturers such as Ford, Chevrolet, and Dodge. When the C0D43 code is triggered, it suggests that there may be a malfunction in the communication between the BCM and other modules, which can lead to inconsistent vehicle behavior such as issues with door locks, lighting, and even starting problems. For instance, a 2016 Ford Fusion might experience random interior lights flickering or failure to unlock the doors remotely. It's crucial to address this code promptly as it can lead to further electrical problems or security issues, making it essential for vehicle owners to understand its implications. Ignoring the C0D43 code can potentially worsen the situation and lead to more expensive repairs down the line. Regular diagnostics using tools like the GeekOBD APP can help in keeping the vehicle running smoothly and catching such issues early on.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0D43 is present:
- The check engine light remains illuminated, indicating a persistent issue with the vehicle's body control module.
- Drivers may experience unresponsive power windows or door locks, which can be frustrating and inconvenient.
- You might notice erratic behavior of the interior lights, such as flickering or lights that do not turn on or off as expected.
- In some cases, the vehicle may have difficulty starting due to BCM miscommunication with the ignition system.
- There could be a noticeable decrease in fuel economy as the vehicle's electrical systems struggle to function optimally.
Possible Causes
Most common causes of C0D43 (ordered by frequency):
- The most common cause of the C0D43 code is a faulty body control module, accounting for roughly 60% of cases. This may happen due to water intrusion, corrosion, or internal failure.
- Another potential cause is damaged wiring or connectors leading to the BCM, which can cause intermittent communication. This occurs in about 25% of reported cases.
- Poor battery connections or low voltage can also trigger this code, as the BCM requires stable power to function correctly. Regular battery maintenance can help prevent this issue.
- Less commonly, a failed ignition switch may impact the BCM's operation, affecting overall vehicle performance.
- In rare instances, software glitches in the BCM can lead to the C0D43 code being set, which may require a software update from the dealer.

Diagnostic Steps
Professional C0D43 Diagnosis Process
Follow these systematic steps to accurately diagnose C0D43. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Begin with an initial visual inspection of the wiring harness and connectors related to the BCM
Step 1: Begin with an initial visual inspection of the wiring harness and connectors related to the BCM. Look for signs of wear, corrosion, or damage (5-10 minutes).
Step 2: Step 2: Use the GeekOBD APP to perform an OBD2 scan
Step 2: Use the GeekOBD APP to perform an OBD2 scan. Retrieve all existing codes and review freeze frame data to understand the context of the fault (10-15 minutes).
Step 3: Step 3: Conduct component testing on the BCM and associated circuits using a multimeter to check for continuity and voltage (20-30 minutes)
Step 3: Conduct component testing on the BCM and associated circuits using a multimeter to check for continuity and voltage (20-30 minutes).
Step 4: Step 4: If repairs are made, perform a system function test to verify that all modules are communicating properly and clear the codes (10-15 minutes)
Step 4: If repairs are made, perform a system function test to verify that all modules are communicating properly and clear the codes (10-15 minutes).
Step 5: Step 5: Complete a road test under various conditions to confirm that the vehicle operates correctly and the C0D43 code does not return (15-20 minutes)
Step 5: Complete a road test under various conditions to confirm that the vehicle operates correctly and the C0D43 code does not return (15-20 minutes).
