My 99 suburban has an anti-theft feature that is somehow related to battery removal. It seems that if you remove or replace the battery it goes into a mode where it will start but will not run. After scouring the service manual for an hour I found a way to reset it. It involves cycling from off to run over the course of 30 minutes.
For some reason now when I go down to the gulf coast the salt air or something down there causes this lockout feature to happen fairly often.
Is there a way to defeat this feature altogether? I do have an OBDII scanner but it shows nothing related to this.
Obviously, when I'm launching the boat down there I NEVER turn the engine off if I'm anywhere close to the boat ramp. :-(
