U0140Lost Communication With Body Control Module
Iată ce înseamnă codul de eroare U0140, de ce apare și ce ai de făcut.
Sistem: Network / module communication
De obicei se poate circula în siguranță pe distanțe scurte, dar verifică problema cât mai curând.
Ce înseamnă U0140
A module on the communication network has stopped receiving messages from the Body Control Module (BCM), the computer that runs many comfort and body electrical features such as lights, locks, wipers, and interior electronics. In practice, several electrical features may stop working or behave strangely. It is usually caused by lost power to the BCM or a break in the network wiring.
Simptome frecvente
- Multiple warning lights or messages on the dash
- Exterior or interior lights not working correctly
- Power locks, windows, or wipers not responding
- Gauges, chimes, or accessories behaving erratically
- Other modules reporting communication faults
Cauze frecvente
Enumerate de la cea mai frecventă la cea mai rară.
- 1Loss of power or ground to the BCM (blown fuse, corroded connector)
- 2Damaged, broken, or shorted CAN bus wiring to the BCM
- 3Corroded, loose, or backed-out connector pins at the BCM
- 4Another module disrupting the communication bus
- 5Failed or faulty Body Control Module
Ce să faci
Have this diagnosed soon, since the BCM controls many electrical features and the loss can affect lights and other functions you rely on. A technician should check BCM power, grounds, and fuses and inspect the network wiring before replacing the module. It is usually safe to drive short distances if your exterior lights and essential controls still work, but get it fixed before depending on the car.
