DTC P1676: Immobilizer-Smartra Message Error: General Description

WARNING: This page is about a different car, the 2022 Genesis G90. However, it is still accessible from the selected car via links, so may be relevant.

The PCM/ECM controls the engine, in a normal way for starting and running, and starts communication with the IBU (SMK + BCM + TPMS), sending a PIN request to the IBU (SMK + BCM + TPMS) and waiting for valid release message from it until the release time period has ended.

In case of IBU (SMK + BCM + TPMS) immobilizer function is locked, the IBU (SMK + BCM + TPMS) answer is the no release message. PCM/ECM enters in the locked state, which causes the activation of the immobilization actions of the engine.

In case of IBU (SMK + BCM + TPMS) immobilizer function state is released, the IBU (SMK + BCM + TPMS) answer is the release message, including the information IBU (SMK + BCM + TPMS) in learn mode and the PIN code.
