To diagnose U0087 using GeekOBD APP, start by scanning for diagnostic trouble codes. Review freeze frame data for context, check wiring and connectors, and perform component tests to pinpoint the issue.
What vehicles are most commonly affected by U0087?
U0087 is frequently seen in 2010-2015 Ford F-150 models, but it can also affect other vehicles across various makes such as Chevrolet and GMC trucks, especially those with complex electrical systems and numerous modules.
How can I prevent U0087 from happening again?
Regular inspections of your vehicle's wiring and connections, along with timely software updates, can help prevent U0087 from recurring. Keeping your vehicle clean and protected from harsh environmental factors also contributes to longevity.
What is U0087?
The diagnostic trouble code (DTC) U0087 indicates a lost communication issue between the control module A and other modules in your vehicle's network. This code typically points to a breakdown in the data communication link, which is critical for various systems such as the engine control module (ECM), transmission control module (TCM), or even the anti-lock braking system (ABS). When your vehicle's onboard computer systems cannot communicate effectively, it can lead to a range of performance issues. Owners may notice symptoms such as warning lights illuminating on the dashboard, erratic vehicle behavior, or even complete system failures in severe cases. U0087 is often triggered by problems like damaged wiring, poor connections, or faulty control modules. Addressing this issue promptly is crucial as it can impact the vehicle's performance and safety. A thorough inspection and diagnostic process is necessary to identify the root causes and ensure all systems function correctly. Ignoring this code could lead to more severe issues and costly repairs down the line.
System: U - Network (Communication, CAN Bus)
Symptoms
Common symptoms when U0087 is present:
- The check engine light may illuminate or blink intermittently, indicating a communication issue.
- Drivers may experience erratic behavior such as stalling or hesitation during acceleration, making the vehicle difficult to control.
- Fuel economy may decrease significantly, often by 10-15%, as the vehicle struggles to manage engine performance.
- In some cases, engine performance may be severely impacted, resulting in reduced power and responsiveness.
- The vehicle may fail to start or enter 'limp mode,' restricting speed and engine power as a safety measure.
Possible Causes
Most common causes of U0087 (ordered by frequency):
- The most common cause of U0087 is a damaged wiring harness or connector, with a likelihood of around 50%. This can stem from wear and tear or exposure to harsh conditions.
- A second possible cause is a faulty control module, which could be due to manufacturing defects or electrical failures. This has about a 30% chance of being the issue.
- Poor connections, often due to corrosion or loose fittings, can also trigger this code. Regular maintenance can help prevent these issues.
- Less common but serious causes include a short circuit in the vehicle's electrical system, which could lead to multiple module failures.
- A rare but possible cause is software glitches in the control module, which may require a software update from the manufacturer.
