Hyundai Creta: General Information / Troubleshooting
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.

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 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.
