I need to have an emission test on a honda element 2004 and the drive cycle needs to be done to get the information, I had a battery change and it erased the information

Disconnect the battery for 5 minutes and reconnect, positive then negative with the key in the ignition, but not turned on. You may have to do a relearn on the security system. You will have to enter the radio code. You won't pass an emissions test until you have done a full drive cycle.

A high level scan tool computer will reset any features that you need resetting.

Before an OBD test or auto diagnostics can be done, most of the emission control system monitors have to complete their checks of the emission control equipment. Depending on the age of your vehicle, if one or two monitors have not yet completed their checks, the vehicle is not ready for an OBD test. If this happens, you will need to drive your vehicle further to allow these monitors to finish testing the equipment. The amount and type of driving needed varies according to the vehicle.

95 Accord is pre-obd 2 and will probably need dedicated Honda diagnostic equipment. There was no requirement at that time to use a standard connector or to place the connector within reach of the driver's seat as with obd 2.

Honda service information should provide more details or for simplicity ask your local Honda dealer to check the emission?

The simplest method would be to check the emissions the old-fashioned way - like it is still done in lots of places, by testing the emissions at the tailpipe with a suitable gasalyser...

Instructions on How to Turn Off The Check Engine Light:
Step 1. If not using a scan tool, locate your vehicle's battery. Disconnect the 12v positive cable (red wire) from battery terminal (+). Leave it disconnect for 5 minutes. While the battery is disconnected, cycle the ignition switch to ON position 3 times. If using a scan tool to turn off the check engine light, follow manufacturers directions. You will need to find your vehicle's OBD II Data Link Connecter (DLC) and connect your scan tool to the DLC, then follow the steps indicated on your scan tool or scan tool manual.

Step 2. Insure ignition switch is OFF. Reconnect the battery 12v positive cable (red wire) to battery terminal (+).

Step 3. Cycle ignition switch to ON position and wait 1 minute, then start your vehicle. Check Engine Light or Service Engine Soon Light should be reset and turned OFF.

Step 4. Drive your vehicle for one week under normal driving conditions. During this period the emissions computer is gathering data and re-learning your vehicle's emissions components and systems. The emissions computer OBDII (on-board diagnostics) system must complete at least one drive cycle (in some cases two or three). A drive cycle is a sequence of internal tests which the emissions computer runs while your vehicle is being driven. This insures all emissions systems are functioning properly. Proper "readiness flags" are set as the computer completes it's cycles. Test cycles are unique to a vehicle. Certain cycles run under very strict parameters, and may require extended driving time to trigger on. Cycle data and readiness flag information is available through your dealership's service department. The data vary widely.

A new cat what was the original code. Usually you need to drive the car for a while after changing a battery (1/2 hour to an hour) on the road so that the cpu as all the data it needs before going for etest especially the new etest machine. The place that change the cat is it the same place that is doing the emission test?

The light could be blinking because you haven't driven it enough for it to register. Drive it for awhile and check again. If the light still blinks, you will need to know what code it has.

Take it to autozone or another place like it and have them read the codes and tell us what they are.

a drive cycle is very complicated and is outlined in the factory emission manual, but here is the short version, u need to do about 20 miles of mixed driving, freeway steady speed, then stop and go and steady low speed, repeated idle times and stop and go, so just drive it in town and on the freeway for a few days and I am sure it will clear the drive cycle test and be ready to pass emission test.

is your check engine light on? if not you can bring it back in to see if the monitors are ready yet, the only thing you can do is drive it until its ready or the CEL comes on good luck and please rate -jeff
