This diagnostic trouble code, BCU 523692.00, occurs when the power module PC0 detects a current exceeding 40 amps at the A3 and D1 outputs, which are linked to the upper worklights and other lighting systems on the cab frame. This overcurrent condition generally indicates a short to ground or a defective component within these circuits:…

Error code BCU 523691.19 occurs when the output for controlling the lower worklights on the cab frame (E20/R and E20/L) or the xenon (HID) worklights on cab frame (E36/R and E36/L) is erroneously energized by more than one control unit. This indicates a communication error or configuration issue within the CAN BUS system, where multiple…

Error code BCU 523691.12 is triggered when the power module (HF) PC6 detects a current of more than 1 amp in lead 1034 to the lower worklights on the cab frame (E20/R and E20/L) or the xenon (HID) worklights on cab frame (E36/R and E36/L), despite these lights being switched off. This condition typically indicates…

The diagnostic trouble code BCU 523691.09 is activated when there is a disruption in the data transfer between the power module (HF) PC6 and the Body Control Unit (BCU). This error manifests as intermittent or nonexistent reception of one or several CAN bus messages from the BCU to the power module (HF) PC6, potentially due…

This diagnostic trouble code, BCU 523691.05, is triggered when the power module (HF) PC6 detects a current of less than 500 mA at the output for the lower worklights on the cab frame (E20 or E36), specifically in lead 1034, while these lights are switched on. Such a low current measurement typically indicates an open…

Error code BCU 523691.04 occurs when the power module (HF) PC6 detects a current exceeding 15 amps in lead 1034, which services the lower worklights on the cab frame (E20 or E36), when these lights are activated. This high current measurement typically indicates a short to ground within the circuit, posing a risk of damage…

Error code BCU 523691.01 is activated when the power module (HF) PC6 detects a supply voltage of less than 3 volts at output (lead 0732) for the worklights on the cab frame (E20 or E36), while these worklights are turned on. This low voltage condition indicates a possible issue in the power supply circuit or…

This error code, BCU 523691.00, is generated when the power module (HF) PC6 detects an overcurrent condition, measuring total amperage in excess of 40 amps across the A1, C1, and D1 outputs. This code is associated with several functions, which are monitored together and may lead to additional diagnostic trouble codes: Output A1: M02 Compressor…

This error code, BCU 523690.02, is activated when the Body Control Unit (BCU) identifies an unrealistic value from the S23/S68 switches, which are used for remote control of the rockshaft on the right and left sides. This condition suggests a potential fault in the switch mechanism or in the signal processing within the BCU.

Error code BCU 523811.00 is activated when the Power Module PC5 in a John Deere vehicle measures a total amperage exceeding 40 amps at the outputs B3, C3, and D3, specifically linked to the Y73 solenoid controlling PTO Speed 1. This diagnostic trouble code suggests a serious electrical issue, such as a short to ground…

Error code BCU 523806.19 is triggered when the Power Module PC5 in a John Deere vehicle reports that the output for the Y75 solenoid controlling PTO Speed 3 is being energized by signals from more than one control unit. This diagnostic trouble code suggests a conflict or error in the CAN (Controller Area Network) bus…
