P0568 Fault Code

Cruise Control Set Signal Malfunction

• What does that mean?

• Causes
• Solutions

The P0568 fault code indicates a malfunction in the Cruise Control Set Signal. This signal is essential for the cruise control system to function properly, allowing the vehicle to maintain a set speed without continuous driver input.

• The cruise control system typically operates by receiving signals from the accelerator pedal, brake pedal, and various other sensors. If there is a fault in the signal indicating that the cruise control is set, the system may not engage or may disengage unexpectedly.
• This can lead to a lack of control over vehicle speed, which can be dangerous in certain driving conditions.

What are the symptoms of the P0568 code?

A driver experiencing a P0568 fault code may notice:

• Inability to activate cruise control.
• Cruise control disengaging unexpectedly while driving.
• Warning lights on the dashboard related to cruise control or the engine.
• Reduced or erratic vehicle speed when cruise control is intended to be engaged.

What causes the P0568 code?

Several factors may contribute to a P0568 code being triggered:

• Faulty cruise control switch that fails to send the correct signal.
• Issues with the wiring or connectors related to the cruise control system.
• Malfunctioning Engine Control Unit (ECU) that misinterprets the cruise control signals.
• Problems with other related components, such as the throttle position sensor or brake light switch.

How to fix P0568?

To resolve a P0568 fault code, consider the following steps:

• Inspect the cruise control switch for proper operation and replace if necessary.
• Check the wiring and connectors for corrosion, damage, or loose connections.
• Ensure that related sensors, like the throttle position sensor and brake light switch, are functioning correctly.
• If necessary, reprogram or replace the Engine Control Unit (ECU) to restore proper signaling to the cruise control system.
