Using the GeekOBD APP, you can scan for DTCs, view freeze frame data, and monitor live data from the power steering system. This will help you pinpoint the specific issue affecting your vehicle.

What vehicles are most commonly affected by C0C37?

This code frequently appears in Ford F-150 models from 2013 to 2018 and Chrysler 300 models from 2015 to 2019. It's essential to check for any manufacturer recalls or TSBs related to power steering issues in these vehicles.

How can I prevent C0C37 from happening again?

Regular maintenance, including checking fluid levels and inspecting wiring for signs of wear or corrosion, can help prevent C0C37 from occurring again. Additionally, keeping your vehicle's software updated may reduce the risk of software-related issues.

What is C0C37?

DTC C0C37 indicates a malfunction within the power steering control module, particularly affecting vehicles from manufacturers like Ford and Chrysler. This trouble code generally arises when the power steering system detects an anomaly in its electrical circuit or communication. Essentially, it suggests that the power steering control module is not functioning as it should, which could hinder the vehicle's steering responsiveness. In real-world terms, this could mean that drivers may experience difficulty when turning the steering wheel, particularly at lower speeds, resulting in a potentially unsafe driving condition. Considering safety, a malfunctioning power steering system can lead to increased steering effort, making it challenging for drivers to navigate tight corners or park their vehicles. This issue can escalate quickly if not addressed, leading to further complications or even complete steering failure. Being aware of this code is crucial for vehicle owners, especially those of 2013-2018 Ford F-150 or 2015-2019 Chrysler 300 models, as it can help them seek timely repairs and maintain vehicle safety.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0C37 is present:

  • The check engine light may illuminate, indicating an issue with the power steering system.
  • Drivers might notice increased difficulty in steering, especially during low-speed maneuvers, leading to potential safety hazards.
  • Unusual noises can occur when turning the steering wheel, such as whining or grinding, signaling a problem within the power steering system.
  • In some cases, the steering wheel may feel unusually stiff, making it challenging to navigate tight spaces or perform regular driving tasks.
  • A sudden loss of power steering assist can happen, resulting in a complete inability to steer the vehicle effectively.

Possible Causes

Most common causes of C0C37 (ordered by frequency):

  1. The most common cause is a faulty power steering control module, which occurs in about 60% of cases. This module can fail due to electrical issues, overheating, or software glitches.
  2. A second cause could be a wiring issue, such as corrosion or short-circuiting in the wiring harness, affecting approximately 25% of reported cases. Regular inspections can help prevent this.
  3. Another cause is low power steering fluid levels, which can lead to overheating and eventual component failure. Keeping fluid levels topped off can mitigate this risk.
  4. Less commonly, a failed steering rack can contribute to C0C37, particularly in older vehicles, which may require a complete replacement.
  5. In rare instances, a software bug in the vehicle's ECU could cause this code to trigger, necessitating a software update from the dealership.
