DTI 523774.04 – Vehicle CAN Bus Under-voltage Warning (CAN)

DTI 523774.04 (DTI )

Code: 523774.04

Shortcode:

Description:

This diagnostic trouble code (DTC) signals that the CAN voltage on the vehicle’s CAN Bus has fallen below 0.5 volts, a level too low to support data transmission. This under-voltage condition can lead to a complete halt in communication across the network, affecting vehicle operation and system coordination.

Reaction:

Data transmission may be suspended to protect against data loss and ensure the safety and integrity of system operations.

Recommendations:

  • Check Wiring and Connections: Thoroughly inspect all related wiring and connections for wear, damage, or looseness that could contribute to voltage drops.
  • Regular Voltage Monitoring: Implement routine checks to monitor the CAN voltage, ensuring it does not fall below operational thresholds.
  • Improve Electrical Integrity: Strengthen electrical connections and enhance grounding where necessary to ensure stable and sufficient voltage supply.

Note:

Maintaining sufficient voltage levels is essential for the smooth operation of the CAN Bus. Effective maintenance strategies and regular monitoring are crucial to avoid voltage-related issues that could impact system functionality.
