Purpose-built OBD2 adapter

The GODIAG GT105 is a specialised OBD2 adapter designed for automotive technicians who perform ECU programming, immobiliser matching and battery replacements. It maintains continuous 12 V power to the vehicle so that stored data, clock settings and anti-theft codes remain intact during service work.

Technicians needing full-protocol support

Workshops that regularly handle VAG fourth- and fifth-generation immobilisers, Toyota ECU synchronisation, Mitsubishi all-key-lost matching or older Porsche Cayenne key learning will benefit from the built-in wake-up button and short-circuit controls. Shops that only require basic code reading or lack compatible programmer hardware will not use the advanced functions.

Integrates with existing programmers

The adapter supplies a full-protocol OBD2 jumper and independent PIN 4 and PIN 5 leads that connect to tools from Autel, Launch, Xhorse, VVDI and similar platforms. A 0.75 mm² sheathed DC cable with 5.5 × 2.1 mm and 5.5 × 2.5 mm plugs draws power from the vehicle battery, while a resettable 7 A fuse protects the circuit during outdoor key-cutting or bench diagnostics.
