Repair the Central Locking of the Tata Sumo Grande

Model: Tata Sumo Grande MK 2 - Years 2010-2014

To repair the central locking of the Tata Sumo Grande, go under the steering column (since this is an Indian-built vehicle, it has right-hand drive), where you will find a multi-plug that connects to the CPU of this electronic device. Remove it for inspection. In this case, there were some unsoldered contacts, which could be repaired with a soldering iron and some skill. The YouTuber also removed the inner door cover to rule out that the issue with the door not closing could be due to any mechanism or wiring inside the door. By exclusion, he arrived at the electronic part. Unfortunately, he did not show how he removed the inner upholstery of the door, while it is evident that the CPU was in an accessible position under the steering column.
