Description:

This diagnostic trouble code, TSC 001881.19, is triggered when the BCU (Brake Control Unit) transmits incorrect sensor status signals on the CAN BUS. These signals indicate either:

• The draft sensor is not available, likely due to incorrect configuration.
• The sensor signal is faulty, possibly due to a circuit problem at the draft sensor.

Reaction:

When this error is detected, the system may experience inaccurate draft sensor data, which can affect various control functions dependent on this information.

Recommendations:

Check Draft Sensor Configuration:

• Verify Configuration:
  • Ensure the draft sensor is correctly configured in the system settings.
  • Reconfigure if necessary.

Inspect Sensor Circuit:

• Check for Circuit Issues:
  • Inspect wiring and connections of the draft sensor for any signs of damage, loose connections, or corrosion.
  • Repair or replace any faulty components.

Validate CAN BUS Communication:

• Check CAN BUS Data Integrity:
  • Ensure that all CAN BUS communications are functioning correctly and no erroneous messages are being transmitted.
  • Repair or replace any faulty CAN BUS components.

Note:

Regular maintenance of the draft sensor and CAN BUS system is essential to prevent incorrect sensor status signals and ensure accurate data transmission.
