A few clicks of the emergency brake pedal turns it offI don't know if you can do that, not sure the lamp module is tied to the computer. But i was able to re-calibrate my speedometer for the tire size though so that was cool . The coolest thing to me is the snapshot feature because you can set the PID's and go drive down the road for when the event happens and hit record, since it is on a buffer it'll capture everything before you hit the button too so you can look at it at the end of the drive. You can also set triggers, like a specific DTC thrown ect. to take the snapshot.
Another cool thing is all the data list etc. are set up like in the official service manuals so if your using the manual to diagnose you just follow the steps listed in the service manual exactly as written for a tech 2. Makes service pretty easy.
Don't get me started on the marvelousness of an ignition/automotive oscilloscope.
'Scopes--in particular, digital storage 'scopes--are terrific for diagnosing fooked electric motors such as heater/AC blower motors, electric fuel pumps, power seat motors, etc.; as well as solenoids like fuel injectors, idle-stop solenoids, and such. You'd need a "low amps" current probe for small loads, and a "high amps" current probe for testing alternators and starter motors.
Customers go wild when you can tell them how many amperes each armature bar of their in-tank fuel pump is drawing, and how fast the fuel pump motor is spinning (typically about 6000 rpm, more-or-less.) You can print out the 'scope pattern showing that--for example--the third armature bar is shorted, drawing way too much current compared to the other seven--or eleven. As a result, the fuel pump is only spinning 5000 rpm, and that's why the fuel pressure is low. Guaranteed fuel pump sale.
The ignition 'scope capacity is best used on Distributor ignitions. They're somewhat less useful on coil-pack ignitions with waste-spark. Coil-near-plug or coil-on-plug ignitions need some dicking-with to use with a 'scope, and it's not at all convenient or easy, you're pretty-much down to one-cylinder-at-a-time.
Does your Modis have the capacity to do cylinder-shorting? I'm thinking "no", but I've never worked with a Modis. I have a full-blown Counselor II (looks like an old-fashioned 19" TV on a metal cart), and a hand-held OTC/Matco automotive 'scope that I've hardly ever used.
Oh. Looks like you got me started after all.
Automotive field? You don't want "just" an oscilloscope. You want a specialized automotive diagnostic 'scope.Shopping for a stand alone oscilloscope now.
I know the really high priced ones are for electrical PhD's but what should I be looking for in the automotive field?
