i am to dumb to operate
First warm up engine to operating temp...
then with vehicle parked and engine running at idle:
- connect scantool (click green connect button),
- goto DVT tab,
- select controller,
- click Activate,
- goto Learning subtab,
- click CASE Relearn (see next line),
- open throttle to increase RPM above 4000, you must do this within 10 seconds (see next line),
- when you get the stumble/misfire (it will be quite notcieable) immediately release throttle,
- let engine spindown to idle,
- after reaching idle, turn off engine and wait 20 seconds,
- while waiting 20 seconds, you can click Deactivate.
You may possibly have to have brake applied and/or parking brake applied during this.
Only one CASE relearn can be done per ignition cycle.

The GM manual will instruct you to apply the brakes for the duration of the CKP learn procedure. Generally, this means keeping your foot on the brake pedal.
Your signature indicates an 0411 PCM - not sure what OS you are running - brake input with a truck OS is C1 pin 33.
The PCM receives 12 volts (10 amp circuit) when the brakes are NOT applied - normally closed switch. When the brakes are applied, this circuit opens and the PCM no longer receives power.
If you are not using a brake switch in your vehicle, a simple switch may be wired for the purpose of the CKP learn procedure. Once you have this switch set up check to see if DTC 0719 or 0724 (brake switch related) are in the PCM memory (these will not turn on the MIL). Clear these codes if present.
When warming up the engine prior to the CKP learn procedure make sure there is power going to the PCM brake input. When brake input is required, simply turn off this switch - the CKP learn procedure should then run.
Regards,
Taz
Depending on your o/s, An easy quick way to do this is just ground C1-32 and C1-34. See what you have in these pin locations at the ecm. Either way ground these to pins to a ground on the chassis or engine and run the test procedure. When you are done un ground the wires and it should have completed the relearn.
