Brief guide: start authorization (EZS/ELV) and required documentation
Guía de una avería documentada. La fecha indica su incorporación a nuestra web.

What to provide to the workshop for EZS/ELV diagnosis: documents, keys and vehicle data before assessing the unit.
Qué ocurre
No start authorization: instrument cluster dark, no terminal 15, immobiliser active or diagnostic error reporting no start permission.
Qué conviene comprobar
Confirm VIN, how many keys are available, visible condition of EZS/ELV, general battery/ground presence and any connector corrosion or moisture.
El siguiente paso
Collect vehicle registration, count of available keys, part number and connector photos. Send these details for assessment; if external checks still show no permission, consider unit evaluation.
