NOTE:

Before beginning this troubleshooting, do a customer diagnostic interview.

When the symptom cannot be duplicated, you can do the troubleshooting using the on-board snapshot information in this procedure. Refer to the diagnostic interview (date, place) and the present total mileage, and compare the total mileage which is estimated from the interview when a failure occurred and the parameter (total mileage) in the on-board snapshot information. Make sure the date when the failure occurred corresponds with the date on which the on-board snapshot information was recorded. If it doesn't, the on-board snapshot information cannot be used in this troubleshooting.

Before beginning this troubleshooting:

?	Make sure the 12 volt battery is fully charged.
?	Make sure the fuel tank is at least 1/4 full.
?	Make sure the engine oil level is correct.

After the troubleshooting, reset the PCM with the HDS to erase the on-board snapshot information recorded on the PCM.
