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.
A/T Controls - Reset and Relearn Adaptive Values
2003 Hyundai Accent L4-1.6LSECTION A/T Controls - Reset and Relearn Adaptive Values

Subject:
AUTOMATIC TRANSAXLE CONTROL MODULE - RESET AND RE LEARN ADAPTIVE VALUES
This bulletin supersedes TSB 05-40-004 to include additional models.
DESCRIPTION:
The PCM or TCM contains logic to adjust solenoid duty and line pressure as needed to compensate for normal clutch wear over the life of the transaxle. This bulletin provides the procedures necessary to reset (erase) and "relearn" the adaptive values in the PCM/TCM.
After the following repairs have been completed, the PCM/TCM adaptive values must be reset in order to provide optimum shift quality:
^ Replace automatic transaxle
^ Reprogram or swap PCM/TCM from another vehicle
Adaptive values must be reset using procedure # 1 or # 2 according to model and model year (MY) as shown below.
I. RESET PCM/TCM ADAPTIVE VALUES
HI-SCAN PROCEDURE:
1. Turn the Ignition key to the "ON" position (do not start engine) and move the shift lever to "P".
2. Attach the Hi-Scan Pro to the data link connector (DLC):
^ Select vehicle
^ Select "AUTOMATIC TRANSAXLE" menu.
^ Select "RESETTING ADAPTIVE VALUES", press "ENTER"
^ Press "ENTER", then "REST" (F1)
^ Turn Ignition key "OFF" for 10 seconds.
II. RELEARN ADAPTIVE VALUES:
NOTE:
After the adaptive values have been reset (erased), an "adaptive learning" procedure must be completed as shown.
3. Attach a Hi-Scan Pro or GDS and select "Engine" menu, "Current Data" menu and throttle position sensor in volts ("THROTTLE POS. SENSOR" "ACCEL. POS. S". or "ACCEL PEDAL 1 VOLT", depending on model).
4. Drive the vehicle until the ATF temperature is within the temperature range shown.
5. Request an assistant to monitor the Hi- Scan while accelerating the vehicle at small throttle openings (approximately 25-30% throttle). Hold the accelerator pedal steady at a throttle position sensor value of 1.45-1.75v during several 1-2-3-4 upshifts. Repeat until normal gear transitions occur.
6. Repeat this procedure for 4-3, 3-2 and 2-1 downshifts.
NOTE:
Adaptive learning does not occur below the ATF temperature range previously shown.

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.
