SubscriberI have a problem with my sons BF falcon. I feel it is related to the drive by wire. My question here is. Does anyone own an OBD2 diagnostic tool? I would like to buy one but know nothing about them.
Do they give out codes that I will then need a manual for this specific model to decipher them, or will the fault be displayed on the screen?
Do all OBD2 scanners do the same thing?
Any other advice before I purchase one would be appreciated.

It's a Ford what did you expect ?

SubscriberIt tends to drive like the cruise control is on. If I take my foot off the pedal it keeps going. It does slow down but very slowly. I was doing 100kph and put it in nuetral and rolled to a stop. The engine rpm stayed at around 2000 until vehicle was almost stopped, at which time it then returned to idle. When braking every thing is normal. It is definitely not the cruise control. When selecting 1st(auto) and then taking foot off the brake and on a flat road, it will slowly go to about 25kph, which is around 2000rpmOriginally Posted by tomisawesome
It also has a minor problem at idle. When the aircon kicks in it idles roughly for a few seconds, almost like an old car if you pulled out the choke when it was warm. It was this problem that my son noticed and told me, so I took it for a drive, and that was when I noticed the other problem.
This vehicle is an Egas model but I am sure it is not a gas specific problem.

In this case the pot is very shiny.

is there a light on the dash? i would start by buying some throttle body cleaner and cleaning out the throttle body, and checking there is nothing restricting the airflow in the intake piping. has the battery been disconnected or flattened in the car recently?
ForumSage
SubscriberNo there is no "check engine" light or any other lights that are not normal.
The battery is about 14 months old and has not been disconnected or flat.
I see where you are coming from with the throttle body clean, but when the car is idling ok, and then put in drive it starts to automaticly and very slowly increase its speed. This does not point to a sticking throttle body.
Dave.
its normal for the rpm to be held up when the car is moving.
2000rpm sounds a little high.if it stumbling a little its probly in first stages of sparkplugs-coil failure or has gas/vac problems.
someone on ford forum found a faulty pcv after a few weeks chasing.

normal--this is to clear the exhaust of any unburnt fuel.
dont go spraying too much around the throttle body--but it should be kept clean inside.also the gas stepmotor spindal.[most common fault].
the convertor will need cleaning now and then and the mixtures checked..it has a idle jet and mixture diaphrams.its not user friendly in a take it back to the dealer and they dont care way.lots of specalist around cashing in on fords silly ways.ive been told that you can adjust mixtures with the ford tools but not with any of the $5000 scanners i played with.
the throttle plate and intake passages have to be clean so the computor knows whats going on.its so smart it falls over when silly things like lower water temps and more throttle opening.the crud the collects on the valve stem can absorb fuel and give intermitant issues etc.
things dont add up so it fails.
battery on these must be disconected now and then to reboot--to help with self learn.if the battery is poor the ecu will compensate untill it cant.
.the car used in normal drive mode is adaptive and will adjust to suit a driver.most complain about poor auto shift after coming into a city after a country drive..if you drive manually the car will eventually have issues and also need a reboot.

"I have a problem with my sons BF falcon. I feel it is related to the drive by wire. My question here is. Does anyone own an OBD2 diagnostic tool? I would like to buy one but know nothing about them."
Yes. Several. You get what you pay for.
"Do they give out codes that I will then need a manual for this specific model to decipher them, or will the fault be displayed on the screen?"
That depends on the tool and weather the code is OBD2 compliant or manufacturer specific. Quite a few varients here. The tool may display the code but not the 'sub code'. On the other hand it may show nothing at all.
For example (made up code). "B2743 Passenger occupancy sensor fault" is what you may get if you're lucky on broad coverage middle of the road ($4000) scan tool. Where as a more manufacturer specific tool would diplay "B2743-2 Passenger occupancy sensor - Short to ground"
Some tools may display the just the code with no discription others may give the wrong discription. Always best to confirm the discription.
"Do all OBD2 scanners do the same thing?"
In theory they probably should but in reality they don't. After all it is a protocol. See above.
"Any other advice before I purchase one would be appreciated."
Try and get something that displays live data. That is probably your biggest friend.
Do your research. But as a tip Launch are producing some good value code readers. They have one for about $150 which is apparently excellent value for money. But I think just displays codes.
Remember there is OBDI and OBDII and don't forget EOBD.
How compliant is the BF Falcon. The BA is not very. Don't be fooled by the connector. Holden only went compliant in the last few models. As a guide only if pin 9 is used it probably is not compliant.
