PARTS INFORMATION

SERVICE PROCEDURE:

1. Using a GDS, check for DTCs in both the "Engine" and "Automatic Transaxle" menus. Record the DTC and description.

2. From the GDS, select:

^ Vehicle

^ "Auto Transaxle" menu

^ "Current Data"

^ "Input speed sensor" and "output speed sensor". Drive the vehicle and monitor the input and output speed sensors. If the sensors show:

^ Continuous output, the wiring currently has no open/shorts. Go to Step 6.

^ No output, go to Step 3

3. Check the wiring harness visually for an open circuit or short circuit to ground. Check for a pinched harness at the PCM/TCM attachment bolts.

4. Disconnect the connectors at the input and output speed sensor and PCM/TCM. Check for bent pins or pins not fully inserted into the connector.

5. If a harness open/short is found, repair or replace the ECM control harness between the PCM/TCM and transaxle and go to Step 8. If not, go to Step 6.








6. P0722 ONLY: For 2006~ Sonata, 2007~ Santa Fe, 2007~ Entourage and 2006~ Azera vehicles, check the ground bolt at the location shown. Confirm the threads are clean and the bolt is tight.





7. If the ground bolts are clean and tight, follow the repair procedure shown above.

8. Drive the vehicle for two key-on to key-off driving cycles. If the codes:

^ Do not set again, return the vehicle to the customer.

^ Set again, go to step 8.

9. Exchange a PCM or TCM from a similar year and model vehicle (excluding vehicles with immobilizer). If the codes:

^ Set again, replace the control wiring harness.

^ Do not set again, replace the PCM or TCM.
