Går det koppla förbi immobilasern så man får igång bilen

Nu vet jag inte vilken antenn du bytt. Vad jag misstänker är att din nyckel inte pratar med anrennringen under ratten. Ta bort batteri minus. Ta bort lite paneler under ratten och ta loss den gröna (?) antennringen under Nyckelhålet och ratten. Spraya elektronik rengörnings spray på, vicka lite på kontakterna för bättre kontakt och sätt tillbaka kontakten. Testa starta nu efter batteriet är inkopplad.

Har läst på en USA site och fick denna information: Make:
Volvo
Code:
ECM-720A
Definition:
Immobilizer Communication (Communication Fault, Signal Missing Or Comparison Fault)
Description:
The engine control module (ECM) contains a code for the immobilizer which is unique to each car. The unique code is checked so that it corresponds to the central electronic module (CEM) and the engine control module (ECM). The electronic immobilizer has another criterion that must be met before it allows the engine to start. A check is performed via CAN communication to ensure that the hardware series number on the brake control module (BCM) corresponds to the number stored in the engine control module (ECM). The hardware series number is automatically stored when downloading software to the engine control module (ECM). If the hardware series number corresponds to the engine control module (ECM) and the brake control module (BCM), the electronic immobilizer will allow the engine to start. The diagnostic trouble code (DTC) is stored (signal missing) if the engine control module (ECM) registers that there is a fault in the CAN communication between the engine control module (ECM) and the brake control module (BCM). The diagnostic trouble code (DTC) is stored (comparison fault) if the hardware series number in the brake control module (BCM) does not correspond to the number stored in the engine control module (ECM). The diagnostic trouble code (DTC) is stored (communication fault) if the engine control module (ECM) registers a fault related to the immobilizer function in the central electronic module (CEM). The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.
Cause:
Signal missing
Fault trace the brake control module (BCM).
Comparison fault
The programmed hardware series number in the engine control module (ECM) does not correspond to the relevant hardware series number in the Brake Control Module (BCM).
Communication fault
Fault trace the central electronic module (CEM)
The engine control module (ECM) or central electronic module (CEM) has been replaced and contains incorrect software.

Jo den antennringen men beter sig likadant

Du får bogsera den till Volvo då. Säkert bara mindre fel.
