E37 anti theft disable

[Taz]

Ok I did the crank relearn procedure this morning (some instructions would have REALLY helped here) and it starts and runs fine now.)

Hello Bill,

Generic CKP system variation learn procedure instructions are included in the Scan Tool User Manual - pages 152 and 153. When you downloaded the EFILive software, user manuals and about a dozen tutorials would have also been downloaded - these are generally downloaded to C:\Program Files\EFILive\V7.5\Doc.

The CKP variance instructions are also included in the OEM service manuals - available from Helm Inc. - the only manuals worth owning in my opinion.


Regards,
Taz

+1 on the GM service manuals. OP could probably benefit from the electronic version (covers all years/models).

Cool! That's great to hear that VFS will run when it sees all the right sensors. How long did it take before the learn started and it settled on an ethanol content %?

Sorry for the late reply...been out of civilization range (Nebraska) for the weekend.

It happens pretty darn quick...within a minute probably it is very close and within the next minute, maybe two, has completely settled. Switching from E~85 to E~10 seemed to go quicker.

Couple of things to note...cruise control doesn't work and the brake pedal doesn't release the TCC (thought lifting throttle does). This is due to a difference in how the system processes brake pedal signals...2007 uses two individual switches, one for lighting (to the BCM) and one for TCC/cruise (to the ECM) whereas 2010 uses a single Brake Pedal Position Sensor (potentiometer) to the BCM. 2010 ECM has no dedicated brake pedal signals. (maybe these are programmable...haven't really looked yet)
