This diagnostic trouble code (TCU 524154.04) is generated if the control unit registers a resistance at the CF proportional solenoid valve that does not correspond with the switch status of the forward clutch, and a voltage drop at the proportional solenoid valve is also detected. This typically indicates a short to ground in the circuit…

This diagnostic trouble code (TCU 524154.03) is generated if the control unit registers resistance and voltage at the CF proportional solenoid valve that do not correspond with the switch status of the forward clutch. This indicates a short to a positive lead in the circuit of the proportional solenoid valve.

This diagnostic trouble code (TCU 524153.05) is generated if the control unit registers a resistance at the solenoid valve that does not correspond with the switch status of BG disk brake. This indicates that the solenoid valve’s circuit is open, leading to insufficient current flow.

This diagnostic trouble code (TCU 524153.04) is generated if the control unit registers a resistance at the solenoid valve that does not correspond with the switch status of BG disk brake, and a voltage drop at the solenoid valve is also registered. This typically indicates a short to ground in the solenoid valve circuit.

This diagnostic trouble code (TCU 524153.03) is generated if the control unit registers resistance and voltage at the solenoid valve that do not correspond with the switch status of disk brake BG. This indicates a short to a positive lead or a defective solenoid valve. The fault can be recognized by the control unit during…

This diagnostic trouble code (TCU 524110.08) is generated if a difference in frequency is detected between the two sensor output signals for transmission output speed. This indicates that the speed in channel 2 is lower than in channel 1, suggesting a potential issue with the B63 sensor or its circuitry.

This diagnostic trouble code (TCU 524110.04) is generated if the control unit detects that the voltage at the signal input from channel 2 of the transmission output speed sensor (B63, lead 6083) is too low. This typically indicates a short to ground in the sensor circuit.

This diagnostic trouble code (TCU 524110.03) is generated if the control unit detects that the voltage at the signal input from channel 2 of the transmission output speed sensor (B63, lead 6083) is too high. This indicates that there is a supply voltage problem or that the sensor’s circuit is open or shorted to a…

This diagnostic trouble code (TCU 524109.10) is generated if the PLC control unit reports a faulty wheel speed sensor (B84) via CAN BUS. In its active state, this fault also generates a diagnostic trouble code at the PLC, which takes priority.

This diagnostic trouble code (TCU 524108.05) is generated if the control unit registers a resistance at the proportional solenoid valve Y1 that does not correspond with the commanded operating status of the hydrostatic unit. This indicates that the circuit of the proportional solenoid valve is open. If diagnostic trouble code TCU 524107.05 is also stored,…
