B2335

THEFT DETERRENT / KEYLESS ENTRY: REMOTE ENGINE STARTER SYSTEM: B2335: Lost Communication with Immobiliser System
B2335 - Lost Communication with Immobiliser System

DESCRIPTION

The certification ECU (smart key ECU assembly) sends the remote engine starter ID to the remote engine starter ECU through the main body ECU (multiplex network body ECU) via the CAN and BRAKES communication line. Then, the remote engine starter ECU certifies the ID code and sends the result to the certification ECU (smart key ECU assembly). When the remote engine starter ECU does not receive the remote engine starter ID from the certification ECU (smart key ECU assembly), this DTC is stored.





INSPECTION PROCEDURE

NOTICE:
* Before replacing the remote engine starter ECU, refer to Registration of the remote engine starter system Remote Engine Starter System.
* Before replacing the certification ECU (smart key ECU assembly), refer to Registration of the engine immobiliser system Engine Immobilizer System (w/ Smart Key System).
