You should avoid driving your vehicle if the C01F2 code is present, as it indicates potential braking issues that can compromise your safety.
How can I diagnose C01F2 myself using GeekOBD APP?
Using the GeekOBD APP, you can scan your vehicle for trouble codes, view freeze frame data, and check the status of the BCM to identify the specific fault.
What vehicles are most commonly affected by C01F2?
The C01F2 code is most prevalent in 2015-2020 Ford Explorers, with some reports in other Ford models during this timeframe.
How can I prevent C01F2 from happening again?
Regular maintenance of your vehicle's braking system, including checking wiring and connections, can help prevent the C01F2 code from reoccurring.
What is C01F2?
The diagnostic trouble code C01F2 indicates a fault within the Brake Control Module (BCM) of your vehicle, which plays a crucial role in the operation of the anti-lock braking system (ABS) and electronic stability control (ESC). This code typically signifies that the BCM has detected an issue that could impair the vehicle's braking performance. When this code is triggered, it may lead to the ABS light or brake warning light illuminating on your dashboard. It's important to understand that such malfunctions can compromise your vehicle's safety systems, potentially leading to longer stopping distances or loss of control in slippery conditions. Drivers may notice symptoms such as a pulsating brake pedal, unusual noises when braking, or a complete failure of the ABS system. If you own a Ford Explorer from 2015 to 2020, this code is particularly relevant, as these models have been known to experience BCM issues. Addressing the C01F2 code promptly is essential not just for your safety but also to avoid more costly repairs if the problem worsens.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C01F2 is present:
- The ABS light illuminates on the dashboard, indicating potential issues with the braking system.
- Drivers may experience a pulsating brake pedal, especially during hard braking or emergency stops.
- Unusual grinding or squeaking noises when applying brakes may signal that the BCM is malfunctioning.
- Inconsistent braking response, such as the vehicle not stopping as quickly as expected.
- The brake warning light may appear alongside the ABS light, indicating further issues in the braking system.
Possible Causes
Most common causes of C01F2 (ordered by frequency):
- The most common cause is a faulty Brake Control Module, which is responsible for managing the ABS and stability control systems (70%).
- Wiring issues, such as damaged or corroded connections within the BCM circuit, can also trigger this code.
- Moisture intrusion in the BCM or its connectors can lead to electrical short circuits or sensor malfunctions.
- Less common causes include software glitches in the BCM that may require reprogramming.
- Rarely, a malfunctioning wheel speed sensor can cause the BCM to report errors, leading to the C01F2 code.

Diagnostic Steps
Professional C01F2 Diagnosis Process
Follow these systematic steps to accurately diagnose C01F2. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Initial visual inspection - Check for any visible damage to wiring, connectors, or the BCM itself (5-10 minutes)
Step 1: Initial visual inspection - Check for any visible damage to wiring, connectors, or the BCM itself (5-10 minutes).
Step 2: Step 2: OBD2 scan using the GeekOBD APP - Retrieve all codes and review freeze frame data to understand the fault context (10-15 minutes)
Step 2: OBD2 scan using the GeekOBD APP - Retrieve all codes and review freeze frame data to understand the fault context (10-15 minutes).
Step 3: Step 3: Component testing - Use a multimeter to test the BCM and associated wiring for continuity and proper voltage (20-30 minutes)
Step 3: Component testing - Use a multimeter to test the BCM and associated wiring for continuity and proper voltage (20-30 minutes).
Step 4: Step 4: Clear codes and perform a system function test - Verify that the ABS and stability control systems operate correctly (10-15 minutes)
Step 4: Clear codes and perform a system function test - Verify that the ABS and stability control systems operate correctly (10-15 minutes).
Step 5: Step 5: Road test verification - Drive the vehicle under various conditions to ensure the code does not reappear and braking performance is normal (15-20 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to ensure the code does not reappear and braking performance is normal (15-20 minutes).
