This diagnostic trouble code, TSC 000628.12, is triggered when an electronic malfunction is registered in the control unit, causing it to fail to boot. This fault may also occur during the reprogramming of the TSC (Tractor Steering Controller).
- John Deere error TSC codes
This diagnostic trouble code, TSC 000597.19, is triggered when the BCU (Brake Control Unit) transmits incorrect sensor status signals on the CAN BUS. These signals indicate either: The brake pedal sensor is not available. The sensor signal is faulty, possibly due to a circuit problem at the brake pedal sensor unit.

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…

This diagnostic trouble code, TSC 000190.19, is triggered when the ECU transmits an engine speed between 100 and 500 rpm for longer than 5 seconds while the tractor is stationary. This can occur if the engine speed drops suddenly or if the ECU sends incorrect engine speed data while the tractor is not in motion.

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.

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…
- John Deere error TIQ codes
This operator information (diagnostic trouble code) is generated when the reverse drive lever is in the position for forward or reverse travel while the tractor is being started or the ignition is being turned on. If this code is generated despite the lever not being in a travel position, an operational checkout should be performed.
