System Check

  1. Connect the HDS to the data link connector.
  2. Turn the ignition switch ON (II).
  3. Monitor the System Check in the Immobilizer Info with the HDS.
  4. If the HDS displays the "Normal", the immobilizer system is OK. If the HDS displays any other messages, check as follows:
    TROUBLESHOOTING CHART

    System Check No. Status Log. Indication System Check Possible Cause
    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 metal such as key chains/key rings/ other keys.
    • Low battery voltage.
    A-2 Possible Communication error between the key and immobilizer unit
    • Intermittent interruption between transponder and immobilizer-keyless control unit.
    • The immobilizer key type is incorrect non-Honda key.
    • Key failure (transponder failure)
    • No communication between the antenna and the immobilizer key by influence of metal such as key chains/key rings/other keys.
    • Low battery voltage.
    A-3 Possible No communication between the key and immobilizer unit
    • The ignition switch was turned on with a non-immobilizer key.
    • The immobilizer key type is incorrect non-Honda key.
    • Key failure (transponder failure)
    • The communication was not good between the antenna and the immobilizer key by influence of metal such as key chains.
    • 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.
    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 No registration of Imoes Unit
    • Imoes unit was not registered.
    • No communication between the imoes unit and the immobilizer control unit-receiver because of low battery voltage.
    • No communication between the imoes unit and the immobilizer-keyless control unit because of interference.
    C-2 Possible Error of communication format in 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.
    D-1 Possible S-net line short
    • Harness short from the ECM/PCM to the immobilizer-keyless control unit. (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 control unit and the ECM/PCM because of interference.
    • Immobilizer-keyless control unit failure
    • ECM/PCM failure
    D-3 Possible No communication between ECM/PCM and Immobilizer 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 Unit is not completed The immobilizer-keyless control unit is not registered. Try to register the immobilizer-keyless control unit using the HDS.
