The {{product}} module enables your vehicle to start. If faulty, the car typically won’t crank and no start signal will be generated.

For the vehicle to start the {{product}}, key, and the engine control unit (ECU or DME) need to be in sync. Secondly, the {{product}} stores the vehicle order (VO). The VO is essentially the coding that knows and controls all the car’s features, similar to the DNA of a human. It has information about the type of transmission, extra features, VIN, engine type, etc. Typical signs of a faulty {{product}} in {{year}} {{brand}} {{engine}} vehicles include: No vehicle crank Vehicle not accepting the key Vehicle starts and stalls Yellow ELV steering lock on the dash Once the {{product}} module fails, it will either require a repair or replacement unit. Repairs can typically be performed if the software on the unit is corrupt, which is often caused by failed software updates or when adding additional keys with incorrect tools. If there is physical hardware damage to the unit, potentially from water or another force or decay, it will likely require a replacement {{product}} unit. Regardless of the type of failure, the ECU Pro can offer you a repair service at a fraction of the OEM repair price. It is recommended that you first send your {{product}} for testing services.
