1. HDS - Connect
2. READ DATA (Engine Oil Life) - Select (USA models)

   1. Select the REPLACE PCM MENU, then select READ DATA, and follow the screen prompts. NOTE:  Doing this step copies (READS) the engine oil life data from the original PCM so you can later download (WRITES) them into the new PCM. If the READ DATA indicates FAILED, go to next step.

3. SCS - Short

   1. Turn the vehicle to the OFF (LOCK) mode. 2. Jump the SCS line with the HDS, and wait more than 1 minute.
