On a conversion 99 Silverado with L92+T43 I retained the old LS1B ECM to send some data on the GMLAN to feed BCM and cluster.
Unfortunately the ECM does not detect a running engine and therefore always turns on the BATTERY CHARGE FAULT display in the DIC.
Is there a way to make the ECM think the engine is running?
What signal determines running? crank sensor?
