Vehicle Driveability Computer Relearn Procedure

If vehicle battery is disconnected for 5 minutes or more, the Powertrain Control Module (PCM) Keep Alive Memory (KAM) will be cleared. KAM is the vehicle operating parameters that are stored in the PCM. Clearing KAM will cause a Diagnostic Trouble Code (DTC) P1000 to set. To clear DTC P1000, OBD-II drive cycle must be performed and completed. Purpose of the drive cycle is to execute each OBD-II monitor and identify any OBD-II concerns. To perform drive cycle, see DRIVE CYCLE PROCEDURE under ADDITIONAL SYSTEM FUNCTIONS in the appropriate TESTS W/CODES - DIESEL article in ENGINE PERFORMANCE.
