What are the most common causes of B0716 and how much does it cost to fix?

Common causes include a faulty steering column lock actuator or a malfunctioning TCM, with repair costs typically ranging from $150 to $400 for part replacements. A thorough diagnostic can help pinpoint the exact issue and provide an accurate estimate.

Can I drive my car with B0716 or should I stop immediately?

It's advisable to stop driving if you see the B0716 code. Continuing to drive can lead to more severe transmission issues and potentially leave you stranded. It's best to have the vehicle inspected as soon as possible.

How can I diagnose B0716 myself using GeekOBD APP?

Using the GeekOBD APP, you can scan for trouble codes and view live data related to the TCM and steering lock. Follow the app's instructions to check for any abnormal readings or codes that could help identify the problem.

What vehicles are most commonly affected by B0716?

The B0716 code is frequently seen in models like the 2015-2018 Honda Accord and 2016-2019 Honda Civic. It's essential to stay updated on recalls or technical service bulletins (TSBs) related to these models for preventive measures.

How can I prevent B0716 from happening again?

Regular maintenance, including inspecting and cleaning the TCM connections, can help prevent issues. Additionally, using quality parts and avoiding aftermarket modifications can reduce the risk of triggering the B0716 code.

What is B0716?

DTC B0716 refers to a transmission control module (TCM) fault, specifically relating to the steering column lock/unlock function. When this code appears, it indicates that the TCM has detected a malfunction in the communication signal between the TCM and the steering lock actuator. This can lead to issues such as the vehicle not starting or the inability to shift gears smoothly. In practical terms, if your car is equipped with this system, you may notice that your steering wheel locks unexpectedly or that your vehicle fails to start. While this issue might not seem immediately critical, it can lead to significant operational problems if left unresolved. Over time, the malfunction could potentially affect the transmission's performance, resulting in shifting delays or erratic behavior. In some cases, the vehicle may enter a 'limp mode,' where it limits speed and power to protect the engine and transmission from damage. Therefore, understanding this code and its implications is crucial for ensuring your vehicle operates safely and efficiently.

Symptoms

Common symptoms when B0716 is present:

  • The check engine light is illuminated on the dashboard, indicating a fault that requires attention.
  • The engine may crank but not start, often due to the steering lock mechanism engaging unexpectedly.
  • There may be difficulty shifting gears, with noticeable delays or rough transitions between gears.
  • The steering wheel could lock unexpectedly, preventing the driver from turning the steering wheel easily.
  • In some cases, the vehicle may enter a reduced power mode, limiting acceleration and overall performance.

Possible Causes

Most common causes of B0716 (ordered by frequency):

  1. The most common cause is a faulty steering column lock actuator, which occurs in about 60% of cases. This component can wear out over time or fail due to electrical issues.
  2. A malfunctioning TCM is the second most common cause, responsible for about 25% of B0716 instances. This could stem from software glitches or hardware failures that disrupt communication.
  3. Loose or damaged wiring in the transmission control circuit can account for approximately 10% of cases. Regular inspections can help prevent this issue by identifying wear and tear.
  4. Less common but serious causes include issues with the vehicle's battery or charging system, which can lead to sporadic electrical faults, affecting the TCM's operation.
  5. Rarely, this code can be triggered by third-party aftermarket parts that interfere with the original specification, leading to compatibility issues.
