Diagnostic trouble code BCU 523920.05 is triggered when the power module PC0 measures a current of less than 500 mA in lead 1047, while the outer worklights on the front of the roof (E18/2) are activated. This condition typically indicates an open circuit, suggesting a break or disconnection in the electrical pathway that should be…

Diagnostic trouble code BCU 523920.04 is activated when the power module PC0 detects a current exceeding 15 amps in lead 1047 while the outer worklights on the front of the roof (E18/2) are switched on. This high current condition typically indicates a short to ground within the circuit, which can lead to overheating, potential damage…

Diagnostic trouble code BCU 523920.01 is generated when the power module PC0 measures a supply voltage of less than 3 volts at lead 0802, specifically when the outer worklights on the front of the roof are switched on. This low voltage condition indicates a power supply fault, potentially due to issues such as inadequate wiring,…

Diagnostic trouble code BCU 523920.00 is triggered when the power module PC0 detects a total amperage exceeding 40 amps at the E3 and H1 outputs, which are associated with both the inner (E18/1) and outer (E18/2) worklights on the front of the roof. This excessive current typically indicates a short to ground or a defective…

Diagnostic trouble code BCU 523919.19 is triggered when there is a communication error involving the inner worklights on the front of the roof (E18/1), specifically the output being energized by more than one control unit. This error typically results from a misconfiguration in the CAN (Controller Area Network) bus system, leading to multiple signals being…

Diagnostic trouble code BCU 523919.12 is triggered when the power module PC0 detects a current of more than 1 amp in lead 1046, even though the inner worklights on the front of the roof (E18/1) are switched off. This condition typically indicates a short in the circuit or an internal fault within the power module…
