Description:

This fault code indicates that the current in the CAN wake-up output circuit has exceeded the 7-amp fuse rating. High current can be caused by a short circuit within the wiring or excessive load from connected components. This condition risks overheating, potential damage to electrical components, and circuit failure.

Reaction:

The control unit may shut down the wake-up circuit to prevent damage and mitigate any risk of electrical fires.

Recommendations:

• Locate and Rectify Short Circuits: Search for and fix any short circuits in the circuit, especially in areas prone to wear or damage.
• Check and Replace Fuses: Ensure that blown fuses are replaced with ones of the correct rating after all issues have been resolved.
• Assess Connected Loads: Evaluate all components and sensors powered by the wake-up circuit for faults that could contribute to high current draw.
• Comprehensive Testing: After repairs, thoroughly test the wake-up circuit to verify that it operates within safe current limits.

Note:

Maintaining the CAN wake-up circuit within specified current parameters is essential for the safe and effective operation of the vehicle’s electrical system, emphasizing the need for continuous monitoring and maintenance.
