IMMOBILIZER SYSTEM DIAGNOSIS
INTRODUCTION TO IMMOBILIZER SYSTEM DIAGNOSIS
The encrypted code should always be re-registered when replacing the immobilizer-ECU.
The immobilizer system consists of the immobilizer-ECU, powertrain control module, ignition key and ignition key ring antenna. If the engine cannot be started by using a registered ignition key, one of these components may be defective. In addition, if the immobilizer system has immobilized the engine, MFI system DTC P1610 will be output. In this case, observe the immobilizer system troubleshooting. Then, if a malfunction is resolved, the MFI system DTC P1610 should not reset.
