ICC 003695.03 – Diesel Particulate Filter Regeneration Inhibit Switch Voltage Above Normal, or Shorted to High Source
ICC 003695.03 (ICC 3695.03)
Code: 003695.03
Shortcode: 3695.03
Description:
This code indicates that the voltage for the Diesel Particulate Filter (DPF) regeneration inhibit switch is above normal, suggesting that the switch is stuck on or there is a short to power. This could be due to a faulty switch, wiring issues, or problems within the control module.
Reaction:
The DPF regeneration process may be inhibited, leading to an accumulation of soot in the filter, increased emissions, and potential engine performance issues. The operator might see a warning light or message on the dashboard.
Recommendations:
- Inspect Inhibit Switch:
- Check the DPF regeneration inhibit switch for proper operation. Replace the switch if it is found to be defective.
- Examine Wiring and Connectors:
- Inspect the wiring harness and connectors associated with the inhibit switch for signs of damage, corrosion, or loose connections.
- Repair or replace any damaged components.
- Test Control Module:
- Verify the functionality of the control module managing the inhibit switch.
- Update the control module software to the latest version.
- Check for Voltage Issues:
- Use a multimeter to check for proper voltage levels in the inhibit switch circuit.
- Repair any issues with high voltage or short circuits.
Note:
Regular inspection and maintenance of the DPF system and associated switches can help prevent issues and ensure proper operation of the regeneration process.
