I. Replace ECM/PCM [Video]

 

When the ECM/PCM is replaced, it is necessary to synchronize the ECM/PCM and the Immobilizer Control Unit-Receiver using the HDS (Honda Diagnostic System). For vehicles with Keyless Access System, the ECM/PCM must also be synchronized with the Keyless Access Control Unit; otherwise, the engine cannot be started.

Step-by-step ECM/PCM Replacement Process:

 

1. From the System Selection Menu, click [IMMOBI].
   
2. Click [Replace ECM/PCM].
   
3. Press tick to continue.
   (Obtain PCM-code from maris2/genpo/Distributor.)
   
4. Input PCM-code and press tick to continue.
   (The PCM-code is calculated using the Acura Code Generator.)
   
5. Turn the ignition switch off.
   
6. Turn the ignition switch on.
   
7. Turn the ignition switch off again.
   (The registration of immobilizer codes into the Immobilizer unit has been completed.)
   
8. Press tick to continue.
   (Check all keys to ensure each can start the engine.)
   
9. Click [NO] when asked if the vehicle is equipped with a Keyless Access Remote System.
   
10. Registration is complete. Press tick to continue.
