Fit L4-1.5L (2008)
Engine Control Module: Removal and Replacement
ECM/PCM Replacement
Special Tools Required
-
Honda diagnostic system (HDS) tablet tester
-
Honda interface module (HIM) and an iN workstation with HDS and CM update software
-
HDS pocket tester
-
GNA600 and an iN workstation with HDS and CM update software
NOTE:
-
Make sure the HDS is loaded with the latest software version.
-
If you are replacing the ECM/PCM after substituting a known-good ECM/PCM, reinstall the original ECM/PCM, then do this procedure.
-
During the procedure, if any READ DATA, WRITE DATA, or other data checks fail, note the failure, then continue.
1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
2. Turn the ignition switch ON (II).
3. Make sure the HDS communicates with the ECM/PCM and other vehicle systems. If it doesn't, go to the DLC circuit troubleshooting. See:
Computers and Control Systems/Testing and Inspection/Component Tests and General Diagnostics/DLC Circuit Troubleshooting If you are
returning from DLC circuit troubleshooting, skip steps 4 through 9,17 through 22, and 25 through 27, and do this after replacing the ECM/PCM:
-
Replace the engine oil and the engine oil filter.
-
Replace the ATF (A/T).
-
Clean the throttle body.
4. Select the PGM-FI system with the HDS.
5. Select the INSPECTION MENU with the HDS.
6. 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.
7. 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.
8. A/T: Select the A/T system with the HDS.
9. A/T: Select the REPLACE TCM/PCM MENU, then select READ DATA and follow the screen prompts.
NOTE:
-
Doing this step copies (READS) the ATF life data from the original PCM so you can later download (WRITE) it into the new PCM.
-
If READ DATA indicates FAILED, continue with this procedure.
10. Turn the ignition switch OFF.
11. Jump the SCS line with the HDS.
12. Remove the passenger's dashboard under cover, the side kick panel, and the glove box.
13. Disconnect the connectors (A), and remove the bolts (B) then remove the ECM/PCM (C).
