Hyundai Tucson: Transmission Control Module (TCM) Inspection Procedure
Hyundai Tucson - Fourth generation (NX4) - (2020-2023) - Workshop Manual / DCT (Dual Clutch Transmission) System / DCT (Dual Clutch Transmission) System (SBC) / Transmission Control Module (TCM) Inspection Procedure
Inspection
- Inspecting TCM ground circuit: Measure the resistance between the TCM
and chassis ground.
(Check the terminal connected to the chassis ground while using the back of the harness connector as the base point for TCM.)
Normal reading (resistance): Below 1
- Inspecting the TCM connector: Disconnect the TCM connector and visually inspect to see whether there is a bend on the ground terminal of the harness connector. Also visually check the connection pressure.
- If no problem is found during inspection in step 1 and step 2, then the problem is with the TCM itself. In this case, replace the TCM and inspect the vehicle again.
- Re-inspecting TCM: Install the TCM that was determined to have malfunctioned from step 3 in another vehicle. Reset the error code and then check the operation in that vehicle. If the vehicle operates without any problems, then inspect the first vehicle with the initial problem again.
Removal
- Prior to replacing the TCM, check the TCM clutch compensation value with the diagnostic tool tool.
- Turn ignition switch OFF and disconnect the battery negative (-) terminal.
- Remove the clutch actuator assembly.
(Refer to Dual Clutch Transmission Control System - "Clutch Actuator & TCM Assembly")
- Loosen the bolts (A) and then removing the TCM (B).
Tighteuning torque: 7.8 - 9.8 N.m (0.8 - 1.0 kgf.m. 5.8 - 7.2 lb-ft)
