Immobilizer 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:

System
Check No. 		System Check Possible Cause Status Log.
Indication 
A-1 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 influence of metal such as key chains/key rings other keys.
  • Low battery voltage.
 		Possible 
A-2 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 was not good between the antenna and the immobilizer key metal such as key chains/key rings/other keys.
  • Low battery voltage.
 		Possible 
A-3 No communication between 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 metal such as key chains/key rings/other keys.
  • Low battery voltage.
  • Immobilizer-keyless control unit failure
 		Possible 
B-1 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.
 		Possible 
B-2 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.
 		Possible 

System
Check No. 		System Check Possible Cause Status Log.
Indication 
C-1 Immobilizer system is not normal The MICU (Imoes unit) was not registered. Try to register the MICU by using ‘‘Imoes unit''.
  • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low.
  • No communication between the immobilizer-keyless control unit and ECM/PCM because of interference.
 		Possible 
C-2 Immobilizer system is not normal 
  • The MICU (Imoes unit) was not registered. Try to register the MICU by using ‘‘Imoes unit''.
  • No communication between the ECM/PCM and the immobilizer-keyless control unit because of low.
  • No communication between the immobilizer-keyless control unit and ECM/PCM because of interference.
 		Possible 
D-1 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 unit and the ECM/PCM because of interference.
  • Immobilizer-keyless control unit failure
  • ECM/PCM failure
 		Possible 
D-2 Immobilizer system is not normal 
  • Blown fuse
  • Harness open from the MICU (Imoes unit) to the immobilizer-keyless control unit.
  • No communication between the MICU (Imoes unit) and the immobilizer-keyless control unit bacause of low battery voltage.
  • No communication between the immobilizer-keyless control unit and the MICU (Imoes unit) because of interference.
  • Immobilizer-keyless control unit failure
  • MICU failure
 		 
D-3 No communication between ECM/PCM and the 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
