ECM To TCM Matching (2.0L Engine)

NOTE: Perform ECM To TCM matching if battery is disconnected or if TCM is disconnected or replaced.

Ensure no DTCs exist, battery is fully charged and cruise control is operating properly (if equipped). Turn all accessories off. Connect Scan Tool (VAG 1551/1552) to data link connector. Turn ignition on. Press 0 and 1 buttons to select ADDRESS WORD 01: ENGINE ELECTRONICS. Press right arrow button.

Press 0 and 4 buttons to select FUNCTION 04: BASIC SETTING. Press "Q" button to enter input. Press 0, 6 and 0 buttons to select DISPLAY GROUP 60. Press "Q" button to enter input. Scan tool should display SYSTEM IN BASIC SETTING 60, followed by four zones numbered 1 through 4. Operate throttle through full range while observing scan tool. ECM stores these values in memory. If values are not as specified, check TCM. See appropriate SYSTEM & COMPONENT TESTING article in ENGINE PERFORMANCE.

If BASIC SETTING is interrupted, check throttle cable adjustment and throttle plate for deposits to ensure throttle is able to return to fully closed position. If throttle is okay, check TCM. See appropriate SYSTEM & COMPONENT TESTING article in ENGINE PERFORMANCE. After procedure is complete (minimum of 30 seconds), press right arrow button. Press 0 and 6 buttons to select FUNCTION 06: END OUTPUT. Press "Q" button to enter input. Turn ignition off.
