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 "Normal" N-1, the immobilizer system is OK. 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 control unit-receiver. Try to register keys using the HDS.
  • 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-2 Possible Communication error between the key and Immobilizer Unit
  • Intermittent interruption between transponder and immobilizer control unit-receiver.
  • 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)
  • No communication between the antenna and the immobilizer key by influence of metal such as key chains/key rings/other keys.
  • Low battery voltage.
  • Immobilizer control unit-receiver 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 control unit-receiver because of low battery voltage.
  • No communication between the immobilizer control unit-receiver 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 control unit-receiver because of low battery voltage.
  • No communication between the immobilizer control unit-receiver 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 control unit-receiver 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 control unit-receiver because of low battery voltage.
  • No communication between the imoes unit and the immobilizer control unit-receiver because of interference.
D-1 Possible S-net line short
  • Harness short from the ECM/PCM to the immobilizer control unit-receiver. (S-net line short)
  • No communication between the ECM/PCM and the immobilizer control unit-receiver because of low battery voltage.
  • No communication between the immobilizer unit-receiver and the ECM/PCM because of interference.
  • Immobilizer control unit-receiver failure
  • ECM/PCM failure
D-2 Possible No communication between Imoes Unit and Immobilizer Unit
  • Blown fuse
  • Harness open from the imoes unit to the immobilizer control unit-receiver.
  • 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 control unit-receiver because of interference.
  • Immobilizer control unit-receiver failure
  • Imoes unit failure
D-3 Possible No communication between ECM/PCM and Immobilizer Unit
  • Blown fuse
  • Harness open from the ECM/PCM to the immobilizer control unit-receiver.
  • No communication between the ECM/PCM and the immobilizer control unit-receiver because of low battery voltage.
  • No communication between the immobilizer control unit-receiver and the ECM/PCM because of interference.
  • Immobilizer control unit-receiver failure
  • ECM/PCM failuer
E-1 - Initial registration of Immobilizer Unit is not completed The immobilizer control unit-receiver is not registered. Try to register the immobilizer control unit-receiver using the HDS.
