System Check

WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The HDS can be used to check the state of the immobilizer key registration and the IMOCD (S-Net) line by doing a 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 "Immobilizer system is normal", the immobilizer system is OK. If the HDS displays any other messages, check as follows:
    IMMOBILIZER SYSTEM TABLE

    Status Log No. System Check Possible Failures
    A-1 Immobilizer system is not normal
    • This key is not registered in the immobilizer control unit-receiver. Try to register keys by using "KEYS".
    • The communication was not good between the antenna and the immobilizer key by influence of metal such as key chains.
    • The communication was not good between the antenna and the immobilizer key by battery voltage low.
    A-2 Immobilizer system is not normal
    • Intermittent interruption between transponder and immobilizer control unit-receiver.
    • The immobilizer key type is different. It is not for this vehicle but for another one or for other company's one.
    • Key failure (transponder failure)
    • The communication was not good between the antenna and the immobilizer key by influence of metal such as key chains.
    • The communication was not good between the antenna and the immobilizer key by battery voltage low.
    A-3 Immobilizer system is not normal
    • The ignition switch was turned on with a non-immobilizer key.
    • The immobilizer key type is different. It is not for this vehicle but for another one or for other company's one.
    • Key failure (transponder failure)
    • The communication was not good between the antenna and the immobilizer key by influence of metal such as key chains.
    • The communication was not good between the antenna and the immobilizer key by battery voltage low.
    • Immobilizer control unit-receiver failure
    B-1 Immobilizer system is not normal
    • The PCM was not registered. Try to register the PCM by using "REPLACE PCM".
    • The communication was not good between the PCM and the immobilizer control unit-receiver by battery voltage low.
    • The communication was not good between the immobilizer control unit-receiver and the PCM by influence of some noise.
    B-2 Immobilizer system is not normal
    • The PCM was not registered. Try to register the PCM by using "REPLACE PCM".
    • The communication was not good between the PCM and the immobilizer control unit-receiver by battery voltage low.
    • The communication was not good between the immobilizer control unit-receiver and the PCM by influence of some noise.
    C-1 Immobilizer system is not normal The imos unit was not registered. Try to register the imos unit by using "REPLACE MICU/IMOES".
    C-2 Immobilizer system is not normal
    • The imoes unit was not registered. Try to register the imoes unit by using "REPLACE MICU/IMOS".
    • The communication was not good between the immobilizer control unit-receiver and the PCM by influence of some noise.
    D-1 Immobilizer system is not normal
    • Harness short from the PCM to the immobilizer control unit-receiver (IMOCD line short).
    • The communication was not good between the PCM and the immobilizer control unit-receiver by battery voltage low.
    • The communication was not good between the immobilizer control unit-receiver and the PCM by influence of some noise.
    • Immobilizer control unit-receiver failure
    • PCM failure
    D-2 Immobilizer system is not normal
    • Blown fuse
    • Harness open from the immobilizer control unit-receiver and imoes unit..
    • The communication was not good between the immobilizer control unit-receiver and the imoes unit by influence of some noise.
    D-3 Immobilizer system is not normal
    • Blown fuse
    • Harness open from the PCM to the immobilizer control unit-receiver.
    • The communication was not good between the PCM and the immobilizer control unit-receiver by battery voltage low.
    • The communication was not good between the immobilizer control unit-receiver and the PCM by influence of some noise.
    • Immobilizer control unit-receiver failure
