DTC P1691 ANTENNA COIL ERROR
COMPONENT LOCATION
EBEC2385
SCMBE6752D
GENERAL DESCRIPTION
E0D9D74B
This wireless communication runs on RF (Radio frequency of 125 kHz). The SMARTRA is mounted at the ignition lock
close to the antenna coil for RF transmission and receiving. The RF signal from the transponder received by the antenna
coil is converted into messages for serial communication by the SMARTRA device. And the received messages from the
EMS are converted into an RF signal, which is transmitted, to the transponder by the antenna.
DTC DESCRIPTION
E58B7CDE
The ECM sets DTC P1691 if there’s any fault in immobilizer antenna coil.
