TSC 000190.31 – Incorrect CAN BUS Message, Engine Speed from ECU (While in Motion)
TSC 000190.31 (TSC 190.31)
Code: 000190.31
Shortcode: 190.31
Description:
This diagnostic trouble code, TSC 000190.31, is triggered when the ECU transmits an engine speed between 100 and 500 rpm for longer than 5 seconds while the tractor is in motion. This can occur due to a sudden drop in engine speed or if the ECU sends incorrect engine speed data while the tractor is moving.
Reaction:
When this error occurs, it may lead to improper engine performance, potentially causing the tractor to experience power loss, reduced speed, or stalling during operation.
Recommendations:
Verify Engine Operation:
- Check Engine Speed:
- Ensure the engine maintains a stable speed during operation.
- Investigate and resolve any issues causing sudden drops in engine speed.
Inspect ECU and Sensors:
- Check ECU Functionality:
- Ensure the ECU is functioning correctly and not transmitting incorrect engine speed data.
- Replace or reprogram the ECU if necessary.
- Check Engine Speed Sensor:
- Inspect the engine speed sensor for proper operation.
- Replace the sensor if it is faulty.
Validate CAN BUS Communication:
- Check CAN BUS Data Integrity:
- Ensure that CAN BUS communications are functioning correctly and no erroneous messages are being transmitted.
- Repair or replace any faulty CAN BUS components.
Note:
Accurate engine speed data is critical for safe and efficient tractor operation. Regular inspection and maintenance of the ECU and engine speed sensor are essential to prevent operational disruptions.
