TSC 000084.15 – Wheel Speed Detected During Calibration (Cab Suspension or TLS)
TSC 000084.15 (TSC 84.15)
Code: 000084.15
Shortcode: 84.15
Description:
This diagnostic trouble code, TSC 000084.15, is triggered when the TSC control unit detects a wheel speed above 0.5 km/h (0.3 mph) via CAN BUS during calibration of the cab suspension or TLS. Potential causes include:
- Defective wheel speed sensor B09/B35 (for PowrQuad transmission) or transmission output speed sensor B63 (for AutoPowr/IVT transmission).
- Incorrect wheel speed or transmission output speed data received via CAN BUS.
- Tractor not positioned on a level surface during calibration, causing movement and resulting in detectable wheel speed.
Reaction:
When this error occurs, the calibration process will be interrupted or fail, preventing proper calibration of the cab suspension or TLS system.
Recommendations:
Inspect Wheel Speed Sensors:
- Check Sensor B09/B35 (PowrQuad) or B63 (AutoPowr/IVT):
- Ensure sensors are properly connected and free from damage.
- Replace defective sensors if necessary.
Verify CAN BUS Data:
- Check CAN BUS Communication:
- Inspect CAN BUS wiring and connections for damage, loose connections, or corrosion.
- Repair or replace damaged components as necessary.
Ensure Level Surface During Calibration:
- Reposition Tractor:
- Place the tractor on a flat, level surface before starting the calibration process to avoid movement and incorrect speed detection.
Additional Actions:
- Repeat Calibration:
- After addressing potential issues, restart the calibration process and ensure no movement during the procedure.
Note:
Ensuring the tractor is stationary and on a level surface is critical for successful calibration. Regularly check sensor conditions and CAN BUS communications to prevent similar issues.
