Hi, my name is***** your mechanic automotive expert, and I will be happy to assist you today. I apologize for any delay.
Dear customer, I think that the alarm system has been deconfigured, your mitsubitshi has the central locking system and the alarm system a little independent from each other, since the vehicle has an alarm system that works on specific programming and a locking module. centralized that works with other specific programming
What I observed is a programming problem in the alarm module, but not in the central locking system.
Therefore what you have first should do is factory data reset through a diagnostic tool with Mitsubishi software.
if this corrects the fault you should check if it is necessary to replace the alarm module.
A problem at the controls level is ruled out because both controls are working normally.
Do you understand me, dear customer?
My goal is to give you the best advise i can, therefore please do not doubt to ask if you have any doubt or if there is anything else i can help you with.
Kind regards, Sebastian.
