Driving with a C0981 code can be risky, as it may affect vehicle stability and braking. It's best to have your vehicle inspected as soon as possible to avoid potential safety hazards.
How can I diagnose C0981 myself using GeekOBD APP?
To diagnose C0981 using the GeekOBD APP, first connect the app to your vehicle's OBD2 port. Use the app to scan for codes and view freeze frame data, which provides insights into when the code was triggered. Follow the troubleshooting steps based on the findings.
What vehicles are most commonly affected by C0981?
C0981 frequently occurs in models like the 2015-2020 Nissan Altima and Rogue, where the Chassis Control Module plays a vital role in vehicle safety systems.
How can I prevent C0981 from happening again?
Regularly inspect wiring and connectors associated with the Chassis Control Module, and ensure that your vehicle's software is up-to-date. Routine maintenance checks can help catch issues before they become severe.
What is C0981?
The diagnostic trouble code (DTC) C0981 indicates a malfunction related to the Chassis Control Module (CCM), particularly in vehicles like the 2015-2020 Nissan Altima and Rogue. This code arises when the CCM detects an internal error or failure in its communication with other vehicle components, leading to potential issues with stability control, traction control, and anti-lock braking systems. The CCM plays a critical role in ensuring the vehicle's handling and safety systems function correctly. When C0981 is triggered, drivers might experience symptoms such as warning lights on the dashboard, compromised vehicle handling, or unexpected behavior during driving. Additionally, the issue could impact the vehicle's braking response, making it vital to address promptly. Ignoring this code may lead to further complications, including a complete failure of the chassis control functions, which can pose serious safety risks. Therefore, understanding this code is essential for maintaining vehicle performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0981 is present:
- The check engine light or ABS warning light remains illuminated on the dashboard, indicating a potential issue with the vehicle's control systems.
- Drivers may notice the vehicle handling poorly, particularly during turns or when braking, leading to decreased driver confidence and safety.
- Fuel economy can decrease significantly, potentially by 10-20%, as the vehicle's stability systems may not operate optimally.
- Unexpected activation of traction control or stability control systems, leading to loss of power when accelerating under certain conditions.
- In some cases, the vehicle may enter a ‘limp mode,’ restricting speed and power until the issue is resolved.
Possible Causes
Most common causes of C0981 (ordered by frequency):
- The most common cause of C0981 is a loss of communication between the Chassis Control Module and other electronic control units, which occurs in about 40% of cases. This can be due to damaged wiring or poor connections.
- Another likely cause is software malfunctions within the CCM itself, which can occur due to updates or glitches, accounting for around 30% of cases.
- A third cause might be related to sensor failures, such as the wheel speed sensors or steering angle sensor, which can lead to incorrect data being sent to the CCM. Regular checks can help prevent these issues.
- Less commonly, a complete failure of the Chassis Control Module could lead to this code, necessitating replacement of the unit, which is a more severe issue.
- Rarely, external factors such as water intrusion into the CCM can cause function loss, though this is less frequent.
