{{year}} {{brand}} {{engine}} {{product}} failure, repairs, and symptoms. {{product}} module failure is a common problem in {{year}} {{brand}} {{engine}} vehicles. The {{product}} module enables your vehicle to start. If faulty, the car typically won’t crank and no start signal will be generated. The {{product}} module is an important module in {{year}} {{brand}} {{engine}} vehicles for two reasons. Firstly, it functions as an anti-theft system in your vehicle. 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. Once we have determined what is wrong with the unit, we will recommend either a repair or replacement {{year}} {{brand}} {{engine}} {{product}}. To get the process started, simply send us your {{year}} {{brand}} {{engine}} {{product}}, KEY, and DME / ECU. Upon checkout, detailed removal instructions will be provided for your vehicle. {{year}} {{brand}} {{engine}} {{product}} repairs/clone highlights: 100% plug-and-play - There is no additional coding required. 1-3 day turnaround - Most of our repairs/clones are completed within 3 days. Time is impacted by the availability of parts and the extent of the damage to the unit. Some units can take between 5-10 days. 6-month warranty - All our ECU repairs/replacements come with a 6-month warranty.
