Using the GeekOBD APP, you can scan for error codes, view freeze frame data for context, and even monitor real-time data from the steering control module to assess its performance.
What vehicles are most commonly affected by C0597?
Vehicles such as the 2015-2019 Chevrolet Silverado and GMC Sierra are frequently affected by C0597. It's advisable to check for any recalls or technical service bulletins (TSBs) related to the steering system.
How can I prevent C0597 from happening again?
Regular vehicle maintenance, including checking electrical connections and ensuring software updates are applied, can help prevent issues leading to C0597.
What is C0597?
The diagnostic trouble code (DTC) C0597 indicates a malfunction within the steering control module, which is a critical component for vehicles equipped with electronic steering systems. This code generally surfaces in various Chevrolet and GMC models from 2015 to 2019, including popular vehicles like the Chevrolet Silverado and GMC Sierra. When the C0597 code is triggered, it typically means that the steering control module has detected a fault in its operation. This might be due to issues such as faulty wiring, a malfunctioning module, or even problems with the vehicle's power supply to the module. In practical terms, this can lead to erratic steering behavior or, in some cases, a complete loss of power steering assistance. This can make driving difficult and dangerous, especially at lower speeds or when maneuvering in tight spaces. Furthermore, if the vehicle's power steering fails, the driver might experience increased effort needed to steer, which can lead to driver fatigue over time. Addressing this issue promptly is crucial to ensure safe vehicle operation and prevent further damage to the steering system or related components.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0597 is present:
- Check engine light stays on constantly, indicating a persistent issue with the steering control system.
- Unresponsive or stiff steering at low speeds, making it difficult to turn the wheel, especially when parking.
- Intermittent power steering loss, where steering feels normal at times but suddenly becomes heavy, causing driver anxiety.
- Strange noises from the steering column when turning, which may indicate underlying mechanical issues in the steering assembly.
- Increased effort required to steer, leading to potential fatigue and discomfort during longer drives.
Possible Causes
Most common causes of C0597 (ordered by frequency):
- Faulty steering control module (60% likelihood) - The most common cause, where the module itself fails due to wear or manufacturing defects.
- Wiring issues (20% likelihood) - Damaged wiring or poor connections can disrupt communication between the steering module and the vehicle's computer.
- Power supply problems (10% likelihood) - Insufficient voltage or electrical issues can lead to the module not functioning correctly.
- Corrosion or dirt in connectors (7% likelihood) - Environmental factors can lead to poor connections, affecting module performance.
- Software glitches (3% likelihood) - Rarely, a software update may be needed to resolve conflicts causing the module to malfunction.
