Required Automatic Transmission Control Module Initialization Procedure (TS 06 01238)

REQUIRED AUTOMATIC TRANSMISSION CONTROL MODULE INITIALIZATION PROCEDURE

TECHNICAL SERVICE BULLETIN

CONDITION

Automatic transmission will not shift properly after Transmission Control Module (TCM) or assembly replacement.

CAUSE

Tech 2 "AT learned initialize" procedure was not performed after A/T assembly replacement or TCM replacement. The transmission module automatically compensates or "learns" and maps transmission wear condition and engine torque output, to provide the best possible shift under any condition. If not reset, the module will shift with the previous shift mapping that may not work properly with the new component.

CORRECTION

Use the Tech 2 to perform the "AT learned initialize" procedure after transmission component replacement, including the transmission assembly and/or the transmission control module replacement, or reprogramming. It is recommended to test drive the vehicle after initialization sufficiently to get the transmission to shift up through 4th lock-up. Decelerate gradually to a full stop at least one time. The AT learned initialize procedure is found in the Tech 2; follow this path to access the AT learned initialize function: SUZUKI -> North America -> (J) FORENZA/RENO -> Power Train -> Transmission -> Misc. Test -> AT learned initialize. See below.
