GODIAG GT112 English Manual

1. The GODIAG GT112 is Designed for:

• Professional auto‑locksmiths performing VAG 2nd /3rd‑generation K‑Line dashboard IMMO offline key‑matching and all‑keys‑lost jobs
• Instrument cluster repair technicians for bench read‑write, mileage correction and IMMO data recovery for VAG K‑Line dashboards
• Automotive electronic repair shops for offline bench diagnosis of disassembled instrument clusters
• ECU / IMMO repair specialists doing bench work for older K‑Line‑based VAG instrument PCBs
• Independent workshops without expensive original VAG dealer test equipment
• Automotive vocational training schools for hands‑on teaching of VAG 2nd & 3rd‑gen K‑Line IMMO systems

2. Supported Key Functions & Features

• Off‑line bench connection for disassembled K‑Line dashboard, converts dashboard signals to standard OBD‑2 port for third‑party programming tools
• Complete bench‑mode workflows: key‑chip & instrument synchronization test, IMMO offline diagnosis, dashboard mileage repair, offline key matching
• Hardware‑built‑in independent ignition switch to simulate vehicle ignition ON/OFF status during bench testing
• Integrated key‑induction coil adapter with LED indicator for smart‑key chip detection
• Intelligent IMMO emergency‑start induction‑area detection to locate the smart‑key sensing position on target vehicles
• Visual LED feedback for key‑chip status diagnosis without connecting additional testers
  Test Result Analysis:
   
  1. The light of the key identifier flashes and then goes out, indicating that the IMMO chip and the chip key are working properly.
  2. The light of the key identifier flashes for a long time, indicating that the chip key and the vehicle's IMMO system do not match, and the chip key needs to be re-matched.
  3. The light of the key identifier does not flash, which means that the vehicle's IMMO system is faulty. Please check the vehicle's IMMO system.
