System Check

  1. Connect the HDS to the data link connector (DLC).
  2. Turn the ignition switch to ON (II).
  3. On the HDS screen, at SYSTEM SELECTION MENU, enter IMMOBI, then select IMMOBILIZER SETUP, select System Check, Number of Keys and Status Log, then select SYSTEM CHECK.
  4. If the HDS displays N-1, the immobilizer system is OK at this time, refer to the STATUS LOG . If the HDS displays any other messages, check as follows:
    STATUS LOG. INDICATION REFERENCE

    System Check No. Status Log. Indication System Check Possible Failures
    A-1 Possible The key is not registered
    • This key is not registered in the immobilizer-keyless control unit. Try to register keys using the HDS.
    • No communication between the antenna and the immobilizer key because of interference from metal such as key chains/key rings/other keys.
    • Low battery voltage.
    A-2 Possible Communication error between the key and immobilizer-keyless control unit
    • Intermittent interruption between transponder and immobilizer-keyless control unit.
    • The immobilizer key type is different. It is not for this vehicle but for another one or for another company's one.
    • Key failure, (transponder failure)
    • No communication between the antenna and the immobilizer key because of interference from metal such as key chains/key rings/other keys.
    • Low battery voltage.
    A-3 Possible No communication between the key and immobilizer-keyless control unit
    • The ignition switch was turned to ON (II) with a non-immobilizer key.
    • The immobilizer key type is different. It is not for this vehicle but for another one or for another company's one.
    • Key failure, (transponder failure)
    • No communication between the antenna and the immobilizer key because of interference from metal such as key chains/key rings/other keys.
    • Low battery voltage.
    • Immobilizer-keyless control unit failure.
    B-1 Possible The ECM/PCM is not registered
    • The ECM/PCM was not registered. Try to register the ECM/PCM using the HDS.
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless control unit and the ECM/PCM because of interference.
    • Open in the IG1 line
    B-2 Possible Error of communication format in ECM/PCM
    • The ECM/PCM was not registered. Try to register the ECM/PCM using the HDS.
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless control unit and the ECM/PCM because of interference.
    C-1 Possible Imoes unit is not registered
    • Imoes unit was not registered.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of interference.
    • Try to register the imoes unit with the HDS.
    C-2 Possible Error of communication format between Imoes unit.
    • Imoes unit was not registered.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of interference.
    • Try to register the imoes unit with the HDS.
    D-1 Possible S-NET line short
    • Harness short from the ECM/PCM to the immobilizer-keyless control unit. (AMMCO (S-NET) line short)
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless unit and the ECM/PCM because of interference.
    • Immobilizer-keyless control unit failure.
    • ECM/PCM failure.
    D-2 Possible No communication between imoes unit and immobilizer-keyless control unit AMMCO (S-NET) line open
    • Blown fuse.
    • Harness open from the imoes unit to the immobilizer-keyless control unit. (AMMCO (S-NET) line open)
    • No communication between the imoes unit and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of interference.
    • Immobilizer-keyless control unit failure.
    • Imoes unit failure.
    D-3 Possible No communication between the ECM/PCM and immobilizer-keyless control unit
    • Blown fuse.
    • Harness open from the ECM/PCM to the immobilizer-keyless control unit.
    • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low battery voltage.
    • No communication between the immobilizer-keyless control unit and the ECM/PCM because of interference.
    • Immobilizer-keyless control unit failure.
    • ECM/PCM failure.
    E-1 -- Initial registration of immobilizer-keyless control unit is not completed The immobilizer-keyless control unit is not registered. Try to register the immobilizer-keyless control unit using the HDS.
