U0140Lost Communication With Body Control Module
Oto co oznacza kod usterki U0140, dlaczego się pojawia i co z nim zrobić.
Układ: Network / module communication
Zwykle można bezpiecznie przejechać krótki dystans, ale jak najszybciej zleć to sprawdzić.
Co oznacza 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.
Typowe objawy
- 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
Typowe przyczyny
Uporządkowane od najczęstszych do najrzadszych.
- 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
Co zrobić
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.
