Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Vehicle Driveability Computer Relearn Procedure
2004 Oldsmobile Bravada AWDSECTION Vehicle Driveability Computer Relearn Procedure
WARNING: This page does not describe the selected car, but rather 98 other vehicles, including the 2001 Saturn SW2, 2001 Saturn SL2, 2001 Saturn SL1, 2001 Saturn SL, and 2001 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.
- If vehicle battery was disconnected or Powertrain Control Module (PCM) was replaced, driving the vehicle will enable the PCM to perform a computer relearn procedure for obtaining proper driveability and engine idle. Until PCM has completed computer relearn procedure, driveability or idle may differ from standard vehicle operation. On A/T models, transaxle shift qualities must be relearned.
- On all models, start engine and warm engine to normal operating temperature. Perform 10 sets of upshifts (1-2, 2-3 and 3-4) at about 30 percent throttle.
- On DOHC engine, while coasting at 35 MPH, slowly accelerate to 1/2 throttle to achieve a 4-3 downshift. Place gearshift in "D3" while coasting at 20 MPH, slowly accelerate at 3/4 throttle to achieve a 3-2 downshift.
- Repeat step 3 5 times. Vehicle driveability computer relearn procedure is now complete.
- On SOHC engine, while coasting at 40 MPH, slowly accelerate to 1/2 throttle to achieve a 4-3 downshift. Place gearshift in "D3" while coasting at 30 MPH, slowly accelerate at 1/2 throttle to achieve a 3-2 downshift.
- Repeat step 5 5 times. Vehicle driveability computer relearn procedure is now complete.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
