A common error code that can be read in certain BMW and Mini models is A559: "Instrument Cluster Power Supply Has Been Switched Off (Closed-circuit Current Cutoff Relay)”. This error often occurs when the voltage in the electrical system falls below a certain level, which can lead to problems with the power supply to the instrument clusterel.
The error code A559 can be read in various BMW and Mini models, including:
Error code A559 refers to a situation where the power supply to the instrument panel has been interrupted. This is usually caused by a voltage that is too low in the 30g-f terminal, which is responsible for the power supply to various components in the vehicle, including the dashboard. This can occur when the car's battery is not sufficiently charged or when the voltage drops below approximately 12.15V.
In addition, the error code can occur due to malfunctions during coding or reading of the vehicle without sufficient power supply. It is common for people to use diagnostic equipment with only the battery voltage, which can interrupt the power supply and cause this error code.
The main causes of error code A559 are:
The first step in solving error code A559 is to check the battery. Make sure it is sufficiently charged and in good condition. If the battery is old or defective, replacing it may fix the error.
However, if the error code continues to appear despite a properly functioning battery, the problem may lie deeper, often in the Footwell Module (FRM). This comfort module is responsible for controlling various electronic components. If this module is defective, all kinds of malfunctions can occur, including problems with the instrument panel.
A permanent solution to this malfunction is to have the footwell module reconditioned. Reconditioning offers a cost-effective way to restore the module to optimum condition without the high costs of complete replacement. ACTRONICS offers professional reconditioning services for BMW and Mini FRM modules, effectively resolving electrical faults such as error code A559.
