NFC troubleshooting

Introduction to NFC troubleshooting

The NFC HW block consists of NFC ASIC, antenna matching circuit, antenna and power supply decoupling

capacitors.
The testing is performed with Phoenix service SW. The menus used are Self Tests and Near Field

Communication.
The following problems can occur with the NFC hardware:

Symptom

Problem

Action

Repair solution

Unable to switch on NFC

on phone user interface

Open circuit solder joints or

component failure of NFC ASIC

or chassis

NFC test coverage

The tests listed in the table below should be performed to verify whether NFC is functional. NFC should be

re-tested after repair.

Self Test: ST_NFC_TEST

NFC ASIC host interface including

I2C, IRQ and FW_RESET

Replacement of engine PWB

Self Test: ST_NFC_ANTENNA_TEST

Antenna matching circuit and

antenna

Replacement of antenna (B-

cover) or engine PWB

Near Field Communication Test:

Single Wire

SWP interface between NFC ASIC

and SIM

Replacement of SIM connector

or engine PWB

Near Field Communication Test:

Upgrade Firmware

Check and update NFC ASIC’s

firmware

The self tests run from Phoenix software are used for fault diagnosis.
If Phoenix software is not available, the functional tests with phone accessories are sufficient to verify the

functionality of NFC.
