Try it. You have nothing to lose. It may be that after the upgrade the system needs to calculate the new input data and readjust the burning characteristics of the engine. Try to take it for a highway drive of 100 miles to give it enough statistics and then take it to Honda for the emissions test! In that way, you will KNOW if their explanation is BS!

SOURCE: Transmission computer software update

Your dealer is shooting you straight. Actually the software update is out. I just had my wife's 2006 R350 software updated yesterday and so far the abrupt downshift has not happened.

SOURCE: 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

SOURCE: My 2002 VW Jetta failed smog due to MIL/Check

if this vehicle is driven in the city almost exclusively, take it out on the freeway a good 30-40 miles prior to taking it back to the smog shop. that should prime all the readiness sensors. make sure your doing some speed and not just going 55 in the slow lane. get the system nice and hot.

If the neutral safety switch is broke on my 2005 jeep liberty how much will it cost to get fix about?

dealer scanned? with there fancy tool>? if not you may fail.
the transmission needs full scans not autozoned,
did you ask the dealer if there are transmission TSB updates
new update transmission programs? y/n.?

so how do you know that switch is bad, ?
no engine stated, not even gas or diesel. 42RLE trans?
no symptoms stated.
just asking (vague parts) ok

there are 4 factors here. and more.
  1. whats really bad. (parts) (did you prove it bad and test it yet?)
  2. cost of parts.
  3. labor costs (vary all over earth , no country or town stated)
  4. and other related damage, collision or rust.

my guess, wild, right p/n switch contact failure.

You might want to call your Honda dealer. Your car might be under a recall: Product Update: IMA Battery Software Update

it should be free if it's under the recall. Just give the dealer your vin# over the phone and have them check it. good luck.
