TSC 000084.19 – Incorrect CAN BUS Message, Wheel Speed from BCU
TSC 000084.19 (TSC 84.19)
Code: 000084.19
Shortcode: 84.19
Description:
This diagnostic trouble code, TSC 000084.19, is triggered when the BCU (Brake Control Unit) transmits incorrect sensor status signals on the CAN BUS. These signals indicate either:
- The wheel speed sensor is not available, likely due to incorrect configuration.
- The sensor signal is faulty, possibly due to a circuit problem at the wheel speed sensor.
Reaction:
When this error is detected, the system may experience inaccurate wheel speed data, which can affect various control functions dependent on this information.
Recommendations:
Check Wheel Speed Sensor Configuration:
- Verify Configuration:
- Ensure the wheel speed sensor is correctly configured in the system settings.
- Reconfigure if necessary.
Inspect Sensor Circuit:
- Check for Circuit Issues:
- Inspect wiring and connections of the wheel speed 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 wheel speed sensor and CAN BUS system is essential to prevent incorrect sensor status signals and ensure accurate data transmission.
