TIA 003509.02 – 5-Volt Supply Voltage Faulty

TIA 003509.02 (TIA 3509.02)

Code: 003509.02

Shortcode: 3509.02

Description:

This diagnostic trouble code (DTC) is generated when the control software detects multiple incorrect output signals from the 5-volt components. This indicates a problem with the 5-volt supply voltage. If related codes TIA 003509.03 or TIA 003509.04 are not stored, it suggests an issue with the ground lead for the 5-volt components.

Reaction:

Limited or no function of the transmission.

Recommendations:

Inspect 5-Volt Supply Voltage:

  • Check the 5-volt power supply to ensure it is providing a stable and correct voltage.
  • Measure the output voltage using a multimeter to confirm it is within the expected range (4.75 V to 5.25 V).

Check Ground Lead:

  • Inspect the ground lead connections for the 5-volt components for any signs of damage, corrosion, or loose connections.
  • Repair or replace any faulty ground connections.

Verify Component Integrity:

  • Ensure that all 5-volt components are functioning correctly and are not causing shorts or drawing excessive current.
  • Replace any faulty components.

Inspect Wiring and Connectors:

  • Check all wiring and connectors associated with the 5-volt supply for damage or wear.
  • Repair or replace any damaged wiring or connectors.

Update Control Software:

  • Ensure that the control software is up-to-date with the latest version from the manufacturer.

Consult Technical Support:

  • If the issue persists, consult technical support for further diagnostic procedures or potential hardware issues.

Note:

Regular inspection and maintenance of the power supply system and related components can prevent issues related to 5-volt supply voltage. Ensuring all connections are secure and free from corrosion is crucial for reliable operation.
