PCM Removal and Installation

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.

1. HDS - Connect
1.
Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode, but do not start the engine.
2.
Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
3.
Make sure the HDS communicates with the PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting.

2. READ DATA (Engine Oil Life) - Select

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 and the starter counter 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.
2.
Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.

4. PCM Cover - Remove
Remove PCM cover (A).


5. PCM - Remove
1.
Disconnect PCM connectors A, B, and C.
NOTE: PCM connectors A, B, and C have symbols (A=?, B=?, C=?) embossed on them for identification.
2.
Remove the PCM (D).


NOTE
If you are removing the PCM, skip the procedures of using the HDS.
If you are substituting the PCM, skip the procedures of WRITE DATA.

1. PCM - Install
1.
Install the PCM (D).
2.
Connect PCM connectors A, B, and C.
NOTE: PCM connectors A, B, and C have symbols (A=?, B=?, C=?) embossed on them for identification.

2. PCM Cover - Install
Install the PCM cover (A).


3. VIN - Input
1.
Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
NOTE: DTC P0630 VIN Not Programmed or Mismatch may be stored because the VIN has not been programmed into the PCM; ignore it, and continue this procedure.
2.
Manually input the VIN to the PCM with the HDS.

4. WRITE DATA (Engine Oil Life) - Select

NOTE: If the READ DATA (engine oil life) failed in "READ DATA (Engine Oil Life) - Select", skip this procedure.
1.
Select the REPLACE PCM MENU, then select WRITE DATA, and follow the screen prompts.

5. Other Procedures for PCM Replacement - Do

If the READ DATA (engine oil life) failed in "READ DATA (Engine Oil Life) - Select", replace the engine oil and the engine oil filter.

6. IMMOBI SYSTEM - Registration

Do the immobilizer system or the keyless access system registration procedure.

7. DTC - Clear

Clear the Pending or Confirmed DTCs with the HDS.

9. PCM - Idle Learn

Do the PCM idle learn procedure.
