Question about 2003 Toyota Matrix

2 Answers

OBD has no power - car runs fine

Have a 2003 Matrix and went to have smog check done. Could not complete the check due to no power to the OBD outlet. Car runs fine, no lights on or difficulty in operation. All fuses I could locate are working. Any ideas what may cause this? I had the smog place check the OBD with two different monitiors and neither showed power.

    Ginko,

    Thanks for the info. I took the car to the dealer yesterday before posting. I was told I likely had a "big problem" However, a bad plug sounds to be more the issue. Any suggestions for me when I take the car back in to repair ?

  • ckmbrown Apr 15, 2009

    Got some good advice suggesting the plug/port may be bad. Any advice as to handle the dealer when I take it back for repair. This is not a warranty issue but I do not wish to be blindsided by the tech if possible.
    Thanks

    Arjun,
    Thanks ! Between yourself and Ginko I feel a little more comfortable with this situation. I will check fuse 14 and wiring a bit closer before I relent and turn it over to the shop.
    Thanks again !

Check fuse 14. See if there is continuity between the fuse and the dlc, because if i remember right there is nothing else in that curciut. look fo broken wires also.
Hope I helped with the repair of your problem. An Accept from you is how I get paid. And a positive feed back tells me how I did with the repair.
Arjun.

The ECU is working for sure, otherwise you will have check engine light and engine would not start.

I know that there are problems with imported models and ODBII readers, read here : Print Page - No Green LED light

A possible explanation is the the ECU has a faulty odbII connector.

I can not get power to the obd port for my 1997 mitssubishi gallant. what do I check?


The OBD port runs off the lighter fuse.Get that fixed and you will probably have power to the port. The black fuses are diodes. One for the PCM, the other for the A/C.

Where is OBD 1 connector location for 1993 Nissan SE-V6 4x4 pick up?


Try disconnecting your battery for 2 minuets then reconnecting the battery . This probably will turn the light off.. then see how long it takes to come back on.. I had Mitsubishi that we never could find out what turned the light on.. The dealer even checked it and could not find the problem (did not even charge us) .. When we would turn off it would stay off for a couple of days.. so to smog it we would turn it off, smog it and worry about it in 2 years..Car ran great, always passed smog eaisly and got over 30mpg and went 200,000 miles..

The person running the test is an idiot. The OBDII test instrument is not capable of determining if there is a warning lamp failure. It is probably guessing based on voltage level, but lamp resistance does normally vary. The test is supposed to be done visually. Take it to someone else, and they will probably be more competent and pass your car.

Hello
Does the light ever come on while you are driving the vehicle? It is possible that the vehicle does not trigger the code on the key cycle when vehicle is connected to the OBDII scan tool (a cycle is the time from when a vehicle is started to the time the vehicle is turned off) you should however most of the time be able to check a vehicles trouble code history to see what may be turning the light on
Good luck

2000 Bettle won't connect to smog machine.


The term "flash" has to do with the on board OBD2 computer flash memory. New software updates or sometimes performance tuning will be programmed to "flash" this memory effectively changing certain preset values such as ignition timing and air/fuel tables. Most cases i have experience with are for the performance market but have been developed in accordance with factory guidlines.

2000 Saturn SL2 fails smog due to failure of OBD Self test


Some vehicles require very specific drive cycles (called "drive traces" if you perform them on a road simulator or dyno) to activate certain self-checks like the catalyst and EVAP monitors. As a general rule, doing some stop-and-go driving around town at speeds up to about 30 mph followed by five to seven minutes of steady 55 mph highway speed driving will usually set most or all of the monitors. Consequently, if you're checking an OBD II system and discover that one or more of the monitors have not run, it may be necessary to test drive the vehicle to set the remaining monitors.

You should talk to a good emission tec, if this is not throwing a code, it is hard to say if that one of the components could be bad. O2,pump,convert, HeO2, every part of the emission system.

With a 1000 miles, and doing what is says above just before the test, and ending driving at the test
should be plenty. If it is not, you will have to have each emission part checked, or when the computer
is plugged in it might show a code that did not trip dash light.

Jetta failing smog due to non communication with OBD - Suggestions?


the no data error can be contributed to a bad interface cable or the scaqn tool was configured wrong and therfore could not connect to the ecm. I would recommend having a scan done again by a certiefied volkswagon tech chances are the mechanics used the wrong adapter cable or reader card. your smog problem could be that your evap canister is clogged therfore gives a bad reading.unfortunately you have to have a scan done but try an independant small shop that delas exclusively with foreign cars such as porche andd mercedez. the will have the correct scan tool and will be much cheaper than a dealership. your cost should be no more than 50 dollars US ... please rate this. thanks
