Circuit Description

WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.

When the transponder code in the ignition key is registered in ECM, the ID code is registered in both ECM and keyless start control module at the same time. This DTC is detected only in case that the ID code cannot be registered in both ECM and keyless start control module when the transponder code in the ignition key is registered in ECM.

NOTE:
  • Troubleshoot DTC P1618 first if both DTC P1615 and P1618 are detected at the same time.
  • After replacing ECM, be sure to register the transponder code in the ignition key with ECM referring to REGISTRATION OF THE IGNITION KEY . After replacing the keyless start control module of the vehicle equipped with the keyless start system, be sure to perform REGISTRATION OF THE IGNITION KEY .
