- Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
- Turn the ignition switch to ON (II).
- Make sure the HDS communicates with the ECM/PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting (see «DLC CIRCUIT TROUBLESHOOTING»(ref-355245-S06359967292010012100000) ). If you are returning from DLC circuit troubleshooting, skip steps 4 through 7,21 through 23, and 26 and 27, then do this after replacing the ECM/PCM: Replace the engine oil (see «ENGINE OIL REPLACEMENT»(ref-290812-S28045107832008072200000) ) and the engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-290812-S04100809992008072200000) ). Clean the throttle body (see «THROTTLE BODY CLEANING»(ref-290823-S19534659422008072200000) ).
- Select the PGM-FI system with the HDS.
- Select the INSPECTION MENU with the HDS.
- Select the ETCS TEST, then select the TP POSITION CHECK, and follow the screen prompts. NOTE: If the TP POSITION CHECK indicates FAILED, continue with this procedure.
- Select the REPLACE ECM/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 ECM/PCM so you can later download (WRITE) it into the new ECM/PCM. If READ DATA indicates FAILED, continue with this procedure.
- Turn the ignition switch to LOCK (0).
- Jump the SCS line with the HDS.
- Remove the passenger's dashboard undercover (see «GLOVE BOX REMOVAL/INSTALLATION»(ref-290806-S13331020522008072200000) ), the side kick panel (see «TRIM REMOVAL/INSTALLATION - DOOR AREAS»(ref-290846-S09306060772008072200000) ), and the glove box (see «GLOVE BOX REMOVAL/INSTALLATION»(ref-290806-S13331020522008072200000) ).
- Cut the plastic cross brace in the glove box opening with diagonal cutters in the area shown, and discard it.
- Remove the relays (A), then remove the bolts (B), and the glove box frame (C).
- Remove the gray 20P ECM/PCM wire harness connector (A) from the ECM/PCM mounting bracket.
- Disconnect the ECM/PCM connectors (B).
- Remove the ECM/PCM mounting bolt (C) and the bracket.
- Remove the nuts (D), then remove the ECM/PCM (E)
- Install the parts in the reverse order of removal.
- Open the SCS line with the HDS.
- Turn the ignition switch to ON (II).
- Manually input the VIN to the ECM/PCM with the HDS. NOTE: DTC P0630 VIN Not Programmed or Mismatch may be stored because the VIN has not been programmed into the ECM/PCM; ignore it, and continue this procedure.
- If the READ DATA (engine oil life) failed in step 7 , go to step 24 . Otherwise, go to step 22.
- Select the PGM-FI system with the HDS.
- Select the REPLACE ECM/PCM MENU, then select WRITE DATA and follow the screen prompts. NOTE: If the WRITE DATA indicates FAILED, continue with this procedure.
- Select the IMMOBI system with the HDS.
- Enter the immobilizer code that you got from iN, and use the ECM/PCM replacement procedure in the HDS; it allows you to start the engine.
- If the TP POSITION CHECK failed in step 6 , clean the throttle body (see «THROTTLE BODY CLEANING»(ref-290823-S19534659422008072200000) ), then go to step 27.
- If the READ DATA failed in step 7 or the WRITE DATA failed in step 23, replace the engine oil (see «ENGINE OIL REPLACEMENT»(ref-290812-S28045107832008072200000) ) and the engine oil filter (see «ENGINE OIL FILTER REPLACEMENT»(ref-290812-S04100809992008072200000) ), ), then go to step 28.
- Select the PGM-FI system, and reset the ECM/PCM with the HDS.
- Update the ECM/PCM if it does not have the latest software (see «ECM/PCM UPDATE»(ref-355245-S27182940282010012100000) ).
- Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-290807-S02808252682008072200000) ).
- Do the CKP pattern clear/CKP pattern learn procedure (see «CRANK (CKP) PATTERN CLEAR/CRANK (CKP) PATTERN LEARN»(ref-290833-S05169572102008072200000) ).
