So i have a 2001 Millenia S 2.3l that i cant get codes from, it has OBDII port and have tested with several different readers, including Autel MD802, and some Delphi that connects to via usb to a computer, (+some cheap ones) they work flawlessly with all other cars but cant connect to my millenia S.
Plugging in a reader gives it power, but no "data connection", having looked at the plug there are 4 pins:
4. chassi ground
5. signal ground
7. ISO9141-2 K-line
16. Battery power.
16 gives 12V, and both grounds are grounded, question is, should there be more pins or does other millenia S have only those 4 aswell?
Via the Diagnostics port under the hood i get no luck either, i am missing the "FEN" pin som i cannot try it with an LED, i have read that just shorting TEN to ground should give u codes via the check engine light, problem is i have never under any circumstanses seen a check engine light.
Are there induvidual bulbs in the instrumentation cluster?, and how hard/much work are they to replace?
WHY i need to read my millenia is that the engine is running poor, missfire for some reason i'm guessing, especially the idle is unstable.
Replaced all the sparkplugs with new ones with the correct gap, 0.8mm (1.1mm was found fitted), while pulling the sparkpluggs 4 came out looking good, while 2 at the front where "gummed up?"(no change in the engine).
bought 2 used ignition coils from a scrapyard (couldnt find any new ones in europe in stock, and the 2 i found was the only 2 on sale in sweden) did make a differance, engine is now running on maby 5cyl+1 perhapps intermittent, up from 4.
i did pull the front sparkplugs again to have a look at them, and they where all coverd in a light film of "soot?", had previously checked that all front ones where getting fuel.
have a quick video but with poor quality, but cant post links yeat
Would really love some help to get it going during the short summer.
