Follow the ECU Relearn procedure before driving on the road
Because your vehicle's engine is electronically controlled by a computer, some control conditions are maintained by power from the battery. When the battery is disconnected or a new battery is installed, the engine must relearn its idle and fuel trim strategy for optimum drive-ability and performance. To begin this process:
1.) With the vehicle at a complete stop, set the parking brake.
2.) Put the gearshift in P (Park) (automatic transmission) or the neutral position (manual transmission), turn of all accessories and start the engine.
3.) Run the engine until it reaches normal operating temperature. Approximately 4-5 minutes.
4.) Allow the engine to idle for at least one minute.
5.) Turn the A/C on and allow the engine to idle for at least one minute.
6.) Drive the vehicle to complete the relearning process.
• The vehicle may need to be driven 10 miles or more to relearn the idle and fuel trim strategy.
• If you do not allow the engine to relearn its idle trim, the idle quality of your vehicle may be adversely affected until the idle trim is eventually relearned.
