@prabhu I messaged ICICI. It didn't work. First register in ICICI website your vehicle details. Take acknowledgement of registration details. Also take a print of Fastag empty form from ICICI Fastag website, fill details and affix passport size photograph. Visit NHAI office by taking filled forms, photocopies of Adhaar, RC book and DL and deposit amount of R's.500. They will arrange your fastag within a week's time. You can contact NHAI Coimbatore office reg Fastag. They can also guide you.
