Kia Sorento: Fault Diagnosis
Features a fail-safe mechanism that provides "limp-home" 4th gear hold
to enable the vehicle to be driven to the owner's home or dealer shop.
Fail-Safe: The TCM provides 4th gear hold and Reverse gear in the event
of a malfunction.
Limp Home: Maintains minimal functionality (Drive(4th gear hold), Reverse)
in the event of a malfunction, making it possible for the vehicle to reach the
dealer shop.
Self-diagnosis
Transaxle Control Module (TCM) is in constant communication with the control
system's components (sensors and solenoids).
If an abnormal signal is received for longer than the predefined duration,
TCM recognizes a fault, stores the fault code in memory, and then sends out
a fault signal through the self-diagnosis terminal. Such fault codes are independently
backed up and will not be cleared even if the ignition switch is turned off,
the battery is disconnected, or the TCM connector is disconnected.
| •
|
Disconnecting a sensor or an actuator connector while
the ignition switch is in the "On" position generates a Diagnostic
Trouble Code (DTC) and commits the code to memory. In such event,
disconnecting the battery will not clear the fault diagnosis
memory. The diagnosis tool must be used to clear the fault diagnosis
memory.
|
| •
|
Before removing or installing any part, read the diagnostic
trouble codes and then disconnect the battery negative (-) terminal.
|
| •
|
Before disconnecting the cable from battery terminal,
turn the ignition switch to OFF. Removal or connection of the
battery cable during engine operation or while the ignition
switch is ON could cause damage to the Transaxle Control Module
(TCM).
|
| •
|
When checking the generator for the charging state, do
not disconnect the battery '+' terminal to prevent the Engine
Control Module (ECM) from damage due to the voltage.
|
| •
|
When charging the battery with the external charger, disconnect
the vehicle side battery terminals to prevent damage to the
TCM.
|
|
Checking Procedure (Self-diagnosis)
| •
|
When battery voltage is excessively low, diagnostic trouble
codes can not be read. Be sure to check the battery for voltage
and the charging system before starting the test.
|
|
| Inspection Procedure (Using the GDS) |
|
1. |
Turn OFF the ignition switch.
|
|
2. |
Connect the GDS to the data link connector on the lower crash
pad.
|
|
3. |
Turn ON the ignition switch.
|
|
4. |
Use the GDS to check the diagnostic trouble code.
|
|
5. |
Repair the faulty part from the diagnosis chart.
|
|
6. |
Erase the diagnostic trouble code.
|
| •
|
After replacing the automatic transaxle, use the GDS to
reset (erase the TCM learning values). Then perform Transaxle
Control Module (TCM) learning to provide optimum shift quality.
(Refer to Automatic Transaxle Control System - "Repair
procedures")
|
| •
|
Adding automatic transaxle fluid.
(Refer to Hydraulic System - "Fluid")
|
| •
|
After servicing the automatic transaxle or TCM, clear
the Diagnostic Trouble Code (DTC) using the GDS tool. Diagnostic
Trouble Codes (DTC) cannot be cleared by disconnecting the battery.
