VERIFIED ENGINEERING SPEC
This 1-page technical case study details a 2011 Chevrolet Cruze no-start issue where the immobilizer light stays on. It explains how an aftermarket aluminum ignition ring shielded the RF signal between the key and the reader coil, causing B3055 and B2955 fault codes.
WHAT IS INSIDE THIS DOCUMENT (CIRCUITS, PINOUTS & SECTIONS):
- Vehicle no-start and immobilizer light symptom description
- GDS diagnostic scan results and fault code analysis
- Key programming and immobilizer transponder replacement attempts
- Identification of aftermarket metal ignition ring interference
- Root cause analysis of RF signal shielding by metal
- Final repair procedure and fault code clearing
