U0514
Dados inválidos recebidos do Módulo de Controle de Espelhos A.
Generic OBD-II
O que significa
A module expected valid network data from the mirror control module A and received messages it could not use, such as bad values or failed checks. The mirror control module A is a module that controls power mirror movement, folding or heating. The wiring and network are carrying something, so this is a data-validity fault rather than a total loss of communication.
Can I keep driving? Usually yes in the short term, but get it read.

Causas comuns
Mais prováveis primeiro
- Poor power or ground at the mirror module, causing garbled or unstable messages

- Fault in the module that receives the data
Como diagnosticar e corrigir
Siga os passos em ordem
- Read codes from all modules, not just one; note any lost-communication or power codes.
- Check battery voltage and charging system; low voltage commonly causes invalid-data codes.
- Check fuses, power and ground at the mirror module.
- Inspect the connector and wiring at the mirror module and the shared network wiring.
- Clear the code and see if it returns; replace or update a module only after power, ground and wiring check out.
