Kia Sorento: Troubleshooting

Has a fail-safe mechanism that maintains 4th gear in "limp home" mode so that the vehicle can be driven to the owner's home or dealer. Fail-safe: The TCM maintains 4th gear and reverse gear in case of a malfunction. Limp Home: Maintains minimum functionality (drive (4th gear hold), reverse) in case of a malfunction, allowing the vehicle to reach the dealer. Self-Diagnosis: The Transaxle Control Module (TCM) constantly communicates with the control system components (sensors and solenoids). If an abnormal signal is received for longer than the specified time, the TCM detects the malfunction, stores the DTC in memory, and then outputs the malfunction signal through the self-diagnosis terminal. Such DTCs are stored and are not erased even when the ignition switch is turned off, the battery is disconnected, or the TCM connector is disconnected.

Caution

Disconnecting a sensor or actuator connector while the ignition switch is in the ON position generates a Diagnostic Trouble Code (DTC) and stores the code in memory. In this case, disconnecting the battery does not erase the diagnostic trouble code memory. To erase the diagnostic trouble code memory, use the diagnostic tester.
Before removing or installing any component, read the diagnostic trouble codes, then disconnect the negative (-) battery terminal.
Before disconnecting the battery cable from the battery terminal, turn the ignition key to the OFF position. Removing or connecting the battery cable while the engine is running or the ignition switch is in the ON position may damage the Transaxle Control Module (TCM).
When inspecting the generator for charging condition, do not disconnect the battery "+" terminal while the engine is running, to prevent the engine from stalling and to protect the Engine Control Module (ECM) from voltage damage.
When charging the battery with an external charger, disconnect the battery terminals from the vehicle to prevent damage to the TCM.

Inspection Procedure (Self-Diagnosis)

1
Turn the ignition off.
2
Connect the GDS to the data link connector located on the lower instrument panel.
3
Turn the ignition on.
4
Use the GDS to check the diagnostic trouble code.
5
Repair the faulty part according to the diagnostic flow chart.
6
Erase the diagnostic trouble code.
7
Disconnect the GDS.
