Kia Soul: Fault Diagnosis
Kia Soul 2014-2019 PS Service Manual / Automatic Transaxle System / 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.
