For a complete wiring diagram, refer to appropriate SYSTEM WIRING DIAGRAMS article  .

1. Perform the following after completion of a diagnostic repair:
   1. With the scan tool check pinion factor (if equipped) for proper tire identification and program or reprogram if necessary.
   2. Connect the scan tool to the Data Link Connector (DLC).
   3. Reconnect any disconnected components.
   4. If the PCM has been replaced or updated (flashed), or the transmission has been repaired or replaced, using the scan tool, perform a Quick Learn Procedure.
   5. With the scan tool, erase all Transmission and Engine DTCs.
   6. With the scan tool, perform a BATTERY DISCONNECT, this will clear the Event Data.
   7. With the scan tool, display Transmission Temperature. Start and run the engine until the Transmission Temperature is HOT.
   8. Check the Transmission fluid level and adjust if necessary. Refer to the Service Information for the Fluid Fill procedure.
   9. Road test the vehicle.
   10. Perform the following shifts from a standing start with a constant throttle opening of 20 to 25 degrees to the speeds of 97 km/h (60 mph); make fifteen to twenty 1 to 2, 2 to 3, 3 to 4, 4 to 5, 5 to 6 upshifts.
   11. Perform the following shifts with speeds below 40 km/h (25 mph); make five to eight wide open throttle kickdowns to 2nd gear. Allow at least 5 seconds each in 3rd and 4th gear between each kickdown.
   12. Check for DTCs during and after the road test.
   13. If after performing the road test, if any shift concerns are noted, perform the drive learn procedure for those affected shifts.
   14. Use the OBDII task manager to run Good Trip time in each gear, this will confirm the repair and to ensure that the DTC does not re-mature.
