Automatic Transaxle Control System: Diagnosis Hyundai Tucson II

Inspection

1. Check the damage and operation of the control cable.
2. Check the damage of the boot.
3. Check the damage and corrosion of the bushing.
4. Check the damage or weakening of the spring.

Scheme 60

1. Set room side lever and T/M side lever to "N" position.
2. Connect room side lever and shift cable.
3. Push cable to "F" direction, shown, to eliminate FREE PLAY.
4. Tighten adjusting nut (A). Tightening torque: 7.8 ~ 11.8 N.m (0.8 ~ 1.2 kgf.m, 5.8 ~ 8.7 lb-ft)
5. After adjusting according Check to be sure that this part operates surely at each range of T/M side corresponding to each position of room lever.

TCM Problem Inspection Procedure

1. TEST TCM GROUND CIRCUIT: Measure resistance between TCM and chassis ground using the backside of TCM harness connector as TCM side check point. If the problem is found, repair it. Specification: Below 1 ohms
2. TEST TCM CONNECTOR: Disconnect the TCM connector and visually check the ground terminals on TCM side and harness side for bent pins or poor contact pressure. If the problem is found, repair it.
3. If problem is not found in Step 1 and 2 , the TCM could be faulty. If so, make sure there were no DTC's before swapping the TCM with a new one, and then check the vehicle again. If DTC's were found, examine this first before swapping TCM.
4. RE-TEST THE ORIGINAL TCM: Install the original TCM (may be broken) into a known-good vehicle and check the vehicle. If the problem occurs again, replace the original TCM with a new one. If problem does not occur, this is intermittent problem. (Refer to «BASIC INSPECTION PROCEDURE»(ref-583710-S32346443232013102900000) .)

1. Turn ignition switch OFF.
2. Disconnect the oil temperature sensor connector.
3. Measure resistance between sensor signal terminal and sensor ground terminal.
4. Check that the resistance is within the specification.

Scheme 64

1. Remove the automatic transaxle assembly. (Refer to «REPAIR PROCEDURES»(ref-583681-S40657198152013102900000) .)
2. Remove the air breeder hose (A).
3. Remove the valve body cover (B). Tightening torque: 12.8 ~ 14.7 N.m (1.3 ~ 1.5 kgf.m, 9.4 ~ 10.9 lb-ft)
4. Remove the bolt (3ea) after disconnecting the solenoid valve connector (B) and the oil temperature sensor connector (A). Tightening torque: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
5. Remove the solenoid valve support bracket (B) and the valve body mounting bolt (A-1ea). Tightening torque: 9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)
6. Remove the torque converter control solenoid valve (A).
