Troubleshooting
Troubleshooting Procedures (cont,dl
ll, Engine Control Module (ECM)/powertrain Control Module (pCM) Reset procedure
NoTE: Resetting the EcM/PcM will erase any stored DTcs and any freeze data. lt will also restart all readiness codemonitors.
Either of the following actions will reset the ECM/PCM.
. Use the OBD ll scan tool or Honda pGM Tester to clear the EClM,s/pCM,s memory.
NorE: see the oBD ll scan tool or Honda PGM Tester user's manuals for specific operating instructions.
' Turn the ignition switch oFF. Remove the BACK uP (7.5 A) fuse from the under-hood fuse/relay box for 10 sec-onds.
NorE: Bemoving the BACK uP (7 5 A) fuse cancels the clock and the radio presets. Make note of the customer,spresets so you can reset then
lll. Final Procedure (this procedure must be done after any troubleshoottng)
1. Remove the SCS Service Connector if it is connected.
NoTE: If the Scs service connector is connected and there are no DTcs stored in the EcMipcM, the MtL will stayon when the ignition switch is turned ON 0l).
2. Do the ECM/PCM Reset procedure.
3. Turn the ignition switch OFF.
