- The 1991 Chevrolet Truck Emissions Manual (Helm) in the (Electronic
- Control Module System) refers to "block learn values". As far as I
- can guess this seems to be some data value(s) stored in the ECM. It
- can be viewed by a Scan Tool. Diagnostic charts give normal values to
- expect. It also appears to be lost when the vehicles battery is
- disconnected. This would lead me to believe it is somehow generated
- by the ECM and stored in there.
-
- How is the "block learn value" generated?
- How is it used by the ECM?
