Honda Element. Manual - part 681

Is DTC P0606 indicated?  

YES -If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE 
ECM/PCM ), then go to step 8. If the ECM/PCM was substituted, go to step 1. 

NO -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, 
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or 
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING. 

DTC P0630: VIN NOT PROGRAMMED OR MISMATCH 

1. Turn the ignition switch ON (II).  

2. Check the VIN with the HDS. 

Does the HDS show the vehicle's VIN?  

YES -Go to step 5. 

NO -Go to step 3. 

3. Input the VIN to the ECM/PCM with the HDS. 

Does the screen show COMPLETE?  

YES -Go to step 5. 

NO -Go to step 4. 

4. Check for DTCs with the HDS. 

Is DTC P0603 indicated?  

YES -Go to the DTC P0603 troubleshooting. 

NO -Go to step 9. 

5. Clear the DTC with the HDS.  

6. Turn the ignition switch OFF.  

NOTE:



Before you troubleshoot, record all freeze data and any on-board 
snapshot, and review the general troubleshooting information (see 
GENERAL TROUBLESHOOTING INFORMATION ).  



This DTC is stored only when the ECM/PCM does not have the VIN 
information of the vehicle. Use the HDS to input the missing VIN 
information.

7. Turn the ignition switch ON (II), and wait 5 seconds.  

8. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P0630 indicated?  

YES -Go to step 9. 

NO -Intermittent failure, the system is OK at this time. If any other Temporary DTCs or DTCs are 
indicated, go to the INDICATED DTCS TROUBLESHOOTING.

10. Check for Temporary DTCs or DTCs with the HDS. 

Is DTC P0630 indicated?  

YES -If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING THE 
ECM/PCM ), then recheck. If the ECM/PCM was substituted, go to step 1. 

NO -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, 
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or 
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING.

Is DTC P0685 indicated?  

NOTE:



Before you troubleshoot, record all freeze data and any on-board 
snapshot, and review the general troubleshooting information (see 
GENERAL TROUBLESHOOTING INFORMATION ).  



If the problem doesn't return after you clear the DTC, or if this DTC is 
stored intermittently, check for loose terminals at the IGP line connectors 
before replacing the ECM/PCM.
