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

Is DTC P0498 indicated?

YES -Check for poor connections or loose terminals at the EVAP canister vent shut valve and the
ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see SUBSTITUTING
THE ECM/PCM ), then go to step 23. If the ECM/PCM was substituted, go to step 1.

NO -Go to step 25.

25. Monitor the OBD STATUS for DTC P0498 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -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 were indicated in step 24, go to the INDICATED DTCS TROUBLESHOOTING.

NO -If the screen indicates FAILED, check for poor connections or loose terminals at the EVAP canister
