PCM Removal & Installation: Removal

NOTE: 

• Make sure the HDS or the MVCI has the latest HDS software version.
• If you are replacing the PCM after substituting a known-good PCM, reinstall the original PCM, then do this procedure.
• If you are removing or substituting the PCM, skip the procedures of READ DATA (Engine Oil Life).

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

  1. Select the PGM-FI system with the HDS

  2. 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, continue with this procedure.
• 3. SCS - Short

  1. Jump the SCS line with the HDS, and wait more than 1 minute.

  2. Turn the vehicle to the OFF (LOCK) mode.

• 4. PCM - Remove
