DTC P1676-00: Smartra Message Error: General Description

WARNING: This page is about a different car, the 2023 Kia Seltos. However, it is still accessible from the selected car via links, so may be relevant.

The ECM/PCM and the SM K communicate when the engine is started to confirm that the proper key is in the vehicle. The SM K and ECM/PCM compare the PIN before the a signal is sent to allow the engine to start. If the PIN do not match, engine start is unavailable.

In case of SMK immobilizer function is locked, the SMK does not carry out a start signal and the ECM/PCM enters in to locked state, which causes deactivation of the engine impossible.

In case of SMK immobilizer function state is released, the SMK will carry out start signal along with SMK learnt mode and PIN code.
