Troubleshooting

?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.

?Troubleshooting

Trouble symptom
Suspect area
Remedy
Shift delay
Damaged clutch / brake
Replace the brake or clutch.
Faulty hydraulic control
Inspect the solenoid valve.
Faulty hydraulic supply
Check the fluid level.
Not performed TCM learning
TCM learning is required.
Vibration of the vehicle when shifting
Damaged clutch / brake
Replace the brake or clutch.
Not performed TCM learning
TCM learning is required.
Faulty hydraulic control
Inspect the solenoid valve.
Faulty hydraulic supply
Check the fluid level.
Fixed gear (shift impossible)
Faulty hydraulic control
Inspect the solenoid valve.
Replace the solenoid valve or valve body.
Faulty harness & connector connection
Check the harness & connector of transaxle.
Faulty TCM
Replace the TCM.
Faulty CAN Communication
Inspect the CAN communication line.
limited gear (shift possible)
Faulty inhibitor switch
Inspect the inhibitor switch.
Faulty input & output speed sensor
Inspect the input & output speed sensor.
Faulty harness & connector connection
Check the harness & connector of transaxle.
Poor acceleration
Faulty hydraulic control
Inspect the solenoid valve.
Faulty hydraulic supply
Check the fluid level.
Faulty oil pump
Replace the oil pump.

?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 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.
7. Disconnect the GDS.
