What Is the Advancetrac System on a Ford F-150?

Advancetrac is Ford’s proprietary stability and traction control system that helps provide improved vehicle control, especially in slippery road conditions or during emergency maneuvers. It builds upon traditional traction control by including additional sensors and advanced software.

Here are the key facts about Ford’s Advancetrac system:

  • Integrates features like anti-lock brakes (ABS), traction control, electronic stability control, and other functions.
  • Uses data from wheel speed sensors, brake pressure sensors, steering angle sensors, and other components to detect wheel slippage and vehicle instability.
  • Can automatically brake individual wheels and reduce engine power to help steer the vehicle in the intended direction.
  • Helps maintain traction and control when accelerating or turning on wet, icy, gravelly, or other low-grip surfaces.
  • Functions at all speeds and adapts its interventions based on driving conditions.
  • Provides an important safety enhancement that can help drivers maintain control if they need to swerve around an obstacle or turn sharply.

So in summary, the Advancetrac system uses various sensors and braking control to optimize stability for the current driving situation. It helps compensate for driver errors and prevent skids or loss of control, especially in bad weather.

Why Does the “Service Advancetrac” Warning Light Come On?

why does the service advancetrac warning light come on

When your Ford F-150’s instrument cluster displays the message “Service Advancetrac” or the yellow wrench/car icon, it means the vehicle has detected a potential problem or fault with the Advancetrac system.

Here are some of the most common issues that can trigger this warning light:

Faulty Wheel Speed Sensor

The wheel speed sensors monitor how fast each wheel is rotating. If one of these sensors becomes covered in dirt, damaged, or fails electrically it can provide inaccurate data to the Advancetrac control module. This causes the system to turn on the warning light since it can’t function properly.

Malfunctioning Steering Angle Sensor

The steering angle sensor detects the position and movement of the steering wheel. Like the wheel speed sensors, it needs to operate properly to determine vehicle stability and required braking corrections. A mechanical problem or electrical failure in this sensor can illuminate the “Service Advancetrac” alert.

Brake System Problems

Since the Advancetrac relies heavily on the brake system to function, issues like worn brake pads, brake fluid leaks, or problems with the brake hydraulic control unit can also activate the warning light. You may even see other brake related alerts like the ABS light or brake warning indicator.

General Electrical Issues

Like most modern vehicles, the Advancetrac system depends on fuses, relays, wiring, connections, modules, and controllers all working properly. Short circuits, faulty grounds, or failures in those components can cause general electrical gremlins that disable Advancetrac and turn on the warning.

While the “Service Advancetrac” light doesn’t necessarily mean the system is completely deactivated, it does indicate a problem that deserves prompt diagnosis and repair. Driving for extended periods with this warning light on could result in degraded traction and stability control.

How to Diagnose and Fix a “Service Advancetrac” Warning?

When the dreaded “Service Advancetrac” message pops up, don’t panic. Here are the general steps to properly diagnose and repair the underlying problem:

Drive to Your Repair Shop – If the vehicle seems to handle and drive normally, proceed cautiously to your repair shop or mechanic to have the light diagnosed. Avoid harsh acceleration or maneuvers.

Diagnostic Scan for Trouble Codes – The technician will first scan for diagnostic trouble codes (DTCs) that indicate which specific Advancetrac component has failed or needs attention.

Inspect Potential Faulty Components – Based on the fault codes set, the mechanic can test, inspect, and confirm the root cause, whether it’s a bad sensor, brake issue, electrical problem, etc.

Perform Necessary Repairs – With the faulty component identified, the technician can replace or repair it to restore normal Advancetrac functionality.

Reset Service Light – Once everything is fixed, the mechanic can reset the “Service Advancetrac” warning light, often by disconnecting the battery or using a scan tool.

Now let’s take a closer look at some of the specific troubleshooting and repair steps for the most common issues:

Diagnosing and Replacing a Faulty Wheel Speed Sensor

A technician confronted with wheel speed sensor trouble codes will first visually inspect the sensors. Look for loose connectors, chafed wires, or signs of damage from road debris. Unplug each sensor and check resistance values with a multimeter and compare to factory specs. Replace any sensor clearly out of spec. Clear debris or moisture from sensors before reinstalling.

Testing and Replacing the Steering Angle Sensor

For steering angle sensor related fault codes, the tech can observe sensor values and errors via diagnostic scanner data. They may also listen and feel for odd noises or sensations while turning the steering wheel to pinpoint mechanical issues. In most cases, the faulty sensor will need to be replaced and then recalibrated.

Investigating Brake and Hydraulic Problems

Brake problems will be investigated through a combination of visual inspection and scanner diagnostics. Check brake pads and rotors for excessive wear. Look for fluid leaks and low fluid level. Check for damaged hydraulic brake lines. The scanner can also retrieve ABS error codes from the brake control module if present. Replace any severely worn pads, rotors, or hydraulic components.

Pinpointing Electrical Gremlins

A good technician will methodically isolate electrical issues that set Advancetrac trouble codes. They’ll wiggle wiring harnesses while watching for faults. Inspect connectors and grounds for corrosion, damage, or looseness. Check fuses and relays. The scanner may also show details like abnormal voltage values that indicate issues in certain modules and controllers that will need further diagnosis.

Properly diagnosing and repairing the cause of Advancetrac warning lights requires automotive skill, wiring diagrams, tools for testing sensors and circuits, and methodical troubleshooting procedures. In some cases, the underlying problem may not be obvious at first. An experienced repair technician can track it down efficiently.

How to Reset the Service Advancetrac Light?

After successfully completing repairs that fix the problem originally triggering the “Service Advancetrac” light, you’ll want to reset the warning indicator. Here are a few common ways to manually reset the service light:

  • Disconnect Battery – After repairs, disconnect the battery for 30+ seconds to allow system capacitors to discharge. This can clear error codes and reset dash lights.
  • Scanner Reset – A mechanic’s diagnostic scanner tool can directly clear stored Advancetrac codes and reset the warning light.
  • Drive and Restart – Driving the vehicle until the engine warms up fully, then turning the ignition off and back on can also reset the light.
  • Multiple Drive Cycles – In some cases, it may require driving through multiple warm-up cycles for the vehicle computer to finally clear the light.

If the light comes back on shortly after resetting, it likely means the underlying problem was not properly repaired, or there is some other fault present.
