Adjustment TCM Learning When shift shock occurs or parts related with the transmission are replaced, TCM learning should be performed. In the following case, TCM learning is required.
Components Location [Vehicle Components] 1. Transmission Control Module(TCM)2. Injector Driver Box(IDB)3. Engine Control Module(ECM)4. Shift lever5.
Inspection 1. Turn the ignition switch ON. 2. Connect the GDS. 3. Emit intensive light toward the photo sensor using a lamp, and check the output voltage change. 4. The voltage will rise with higher intensive light and fall with lower intensive light.
