What is C1047?
DTC C1047 refers to a fault detected in the vehicle's ABS (Anti-lock Braking System) or traction control system. This code indicates that the system has detected an issue within the wheel speed sensor circuit or related components. When the ABS module notices discrepancies in wheel speed data, it triggers the C1047 code. This fault can lead to compromised braking performance and traction control, making it important for vehicle safety. Drivers may experience issues such as the ABS warning light illuminating on the dashboard, and in some cases, they may feel the vehicle's braking system behaving unexpectedly. For example, the brakes might engage or disengage erratically, leading to potential safety hazards. It's crucial for car owners, particularly those with 2015-2019 Ford F-150 models, to address this code promptly to ensure safe driving conditions. This problem is not exclusive to Ford; it can also affect vehicles from various manufacturers that utilize similar ABS technology. Understanding this code and its implications can help drivers take appropriate action before the problem worsens.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1047 is present:
- ABS warning light illuminates on the dashboard, indicating a malfunction in the braking system.
- Unusual braking behavior, such as brakes not engaging when pressed or engaging too harshly, can be felt during driving.
- Degraded traction control, leading to skidding or slipping of the vehicle on wet or slippery surfaces, which can be dangerous.
- Increased stopping distances due to improper functioning of the ABS system.
- Potential noise from the ABS module or wheel speed sensors, which may indicate electrical or mechanical failure.
Possible Causes
Most common causes of C1047 (ordered by frequency):
- The most common cause is a faulty wheel speed sensor, accounting for about 65% of C1047 occurrences. These sensors can become damaged from road debris or corrosion.
- Wiring issues, such as frayed or shorted wires in the ABS circuit, can also trigger this code, often leading to intermittent faults.
- Poor connections at the wheel speed sensor or ABS module connectors can lead to loss of signal, making up about 15% of the causes.
- In rare cases, a malfunctioning ABS control module itself can result in this code, which may require extensive diagnostics and replacement.
- Environmental factors, such as exposure to moisture or road salt, can lead to corrosion of electrical components, although this is less common.
