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" N-1, the immobilizer system is OK at this time, refer to STATUS LOG  . If the HDS displays any other messages, check as follows:
SYMPTOM TROUBLESHOOTING

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 by interference from 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-Acura key.
  • Key failure (transponder failure)
  • No communication between the antenna and the immobilizer key by interference from 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-Acura key.
  • Key failure (transponder failure)
  • No communication between the antenna and the immobilizer key by interference from metal, such as key chains/key rings/other keys.
  • Low battery voltage.
  • Immobilizer-keyless control unit failure
B-1 Possible The PCM is not registered
  • The PCM was not registered. Try to register the PCM using the HDS.
  • No communication between the PCM and the immobilizer-keyless control unit because of low battery voltage.
  • No communication between the immobilizer-keyless control unit and the PCM because of interference.
B-2 Possible Error of communication format in PCM
  • The PCM was not registered. Try to register the PCM using the HDS.
  • No communication between the PCM and the immobilizer-keyless control unit because of low battery voltage.
  • No communication between the immobilizer-keyless control unit and the 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-keyless control unit 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 PCM to the immobilizer-keyless control unit. (S-net line short IMOCD)
  • No communication between the PCM and the immobilizer-keyless control unit because of low battery voltage.
  • No communication between the immobilizer-keyless unit and the PCM because of interference.
  • Immobilizer-keyless control unit failure
  • PCM failure
D-2 Possible No communication between Imoes Unit and Immobilizer Unit
  • Blown fuse
  • Harness open from the imoes unit to the immobilizer-keyless control unit.
  • 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 PCM and Immobilizer Unit
  • Blown fuse
  • Harness open from the PCM to the immobilizer-keyless control unit.
  • No communication between the PCM and the ' immobilizer-keyless control unit because of low battery voltage.
  • No communication between the immobilizer-keyless control unit and the PCM because of interference.
  • Immobilizer-keyless control unit failure
  • PCM failure
