J,ai un code d'erreur check engine...

P0600
Serial Communication Link Malfunction


Qu'est -ce que c'est et qu'est ce qui peut causer ça ?
 
If you have no other codes then it may be the ECU grounds for the CAN BUS controller.

Take the battery out and locate the ECU. Carefully unplug it (I broke mine) and check the condition of the contacts and wire harness. Repair harness damage depending on damage. Clean connector with contact cleaner apply dielectric grease and reinstall. Check ground point for ECU. Put it all back together and reset the codes if you can or drive for a while and see if the communication is fixed.

If that does not help I hope you get another code cause this one is a PITA
