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.

Questions about this item

What type of vehicle battery do I need to supply power to the GT105 for outdoor use?

The adapter draws power from a 12 V vehicle battery via the supplied battery clips and DC cable.

Will the GT105 keep the ECU awake on a 2016 Ford when all smart keys are lost?

Yes, the full-protocol OBD2 jumper works with VVDI, OBD-Star or Autel equipment to program 2016-on Ford smart keys.

How can I confirm the GT105 is maintaining power while I swap the battery?

The clock stays correct, the speaker remains unlocked, IMMO does not lock, and no fault codes appear.
