This would be supported by the scan tool from monodax.

I have not seen it in the current version.

It might be supported in the upgraded pro version to be released in the future.

Instructions for performing a Crank Position Sensor Learn.

Please note the following precautions:
· Apply the vehicle's parking brake.
· Close hood.
· Turn off all accessories (including A/C).
· Place transmission in park (auto) or neutral (manual).
· Keep foot on brake during the learn procedure.
· Only one successful learn procedure per ignition cycle is learnt.
· Once the learn procedure is started, you have 10 seconds in which to complete the test.

The four monitors will display the following values from the vehicle:
· ECT - Engine coolant temperature must be between 150°F and 220°F (65°C and 105°C).
· RPM - Engine speed should be below 2400rpm prior to starting the learn procedure.
· TPS - Throttle position sensor.
· VSS - Vehicle speed sensor.

None of the following diagnostic trouble codes must be set - or the CKP learn procedure will not run.
· P0335 Crankshaft Position (CKP) Sensor A Circuit
· P0336 Crankshaft Position (CKP) Sensor A Performance
· P0341 Camshaft Position (CMP) Sensor Performance Bank 1 Sensor A
· P0342 Camshaft Position (CMP) Sensor Circuit Low Bank 1 Sensor A
· P0343 Camshaft Position (CMP) Sensor Circuit High Bank 1 Sensor A
· P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low
· P0118 Engine Coolant Temperature (ECT) Sensor Circuit High
· P1539 Air Conditioning (A/C) Clutch Feedback Circuit High Voltage
· P1546 Air Conditioning (A/C) Clutch Feedback Circuit Open
· P0705 Transmission Range (TR) Switch Circuit
· P0706 Transmission Range (TR) Switch Performance
· P1810 Transmission Fluid Pressure (TFP) Position Switch Circuit
· P1825 Internal Mode Switch-Invalid Range

Procedure

Start the engine and allow it to idle until it has reached operating temperature:
150°F or 65°C.
Once all four monitors are green, the [CKP Learn] button will be enabled.
During the learn procedure the four monitors will not be updated.

· Click on the [CKP Learn (F3)] button - or press the F3 hotkey.
· If you have configured a delayed start, wait for the delay to elapse. When the delay has elapsed the alarm sound will be played and EFILive will initiate the learn procedure.
· Using the vehicle's accelerator pedal, raise the engine speed to 5,000rpm. The PCM will cut fuel to the fuel injectors once the engine reaches the required speed which may be prior to 5,000rpm.
· When the fuel injectors are cut, the engine will stumble momentarily, release the throttle immediately. The PCM will only cut the injectors for about 1/2 second.
· Allow the engine speed to drop back to idle.
· Turn the ignition OFF for at least 15 seconds to allow the PCM to "save" the learned info.


hope this helps

cheers

Any idea of when this will be available?

[FeetDry]

I don't believe Dax or TC ever said they would support crank relearn, (or any Mode06 operation). I doubt it is an easy task to support.

Actually I remember James sayinmg that he is going to work in the CASE relearn function into the Pro version of MXScan.

That would be sweet, even though I know someone with access to a Tech II, I would like to be able to do it myselfe.

[Hog]

Yes the Tech 2 is a very handy device. Thats what all the dealerships use around here. Having friends is cool.

James: any updates as far as the crank relearn; and is the PRO version ready yet? I am moving from the "black box" to the 0411. Want to be completely ready. Thanks!
