| Abstract: | A CROWN 3.0 with smart entry start system can not be started sometimes. Through fault code reading, data flow and waveform analysis and line measuring, the starter, P/N gear switch, ECUs of transceiver key and steering-locking were analyzed so that the reason and resolution of no starting were found. The reason was that the steering-locking actuator stuck sometimes. |
