DTC AND DIAGNOSIS

DTC for Selector Lever

Defective program
memory

Defective data memory

Faulty MCU reset

Faulty MCU data
process

Faulty MCU watchdog
function

Too long MCU data
throughput time

Low battery voltage

Faulty backup lamp
operating current

Faulty solenoid
operating current

Cause:

The calculated checksum value is not consistent with the stored
checksum value.

Symptom: - Solenoid valve is inoperative.

- Backup lamp is OFF.

- CAN bus is OFF.

- All shift lever position indicators are OFF.

Action:

Reset the unit by cyling the ignition switch (OFF 

→ ON) several times.

Cause:

The  malfunction is occurred during the RAM memory test with
the ignition ON.

Symptom: - Solenoid valve is inoperative.

- Backup lamp: OFF

- CAN bus: OFF

- All shift lever position indicators: OFF

Action:

If the malfunction stays after turning the ignition switch from OFF
to ON, replace the TGS lever.

Cause:

The malfunction is occurred during the microprocessor test with
the ignition ON.

Symptom: - Solenoid valve is inoperative.

- Backup lamp is OFF.

- CAN bus is OFF.

- All shift lever position indicators are OFF.

Action:

Reset the unit by cyling the ignition switch (OFF 

→ ON) several

times.

Cause:

The battery voltage is low.

(Specified value: less than 8.0 ± 0.3 V for 50 ms)

Symptom: All shift lever position indicators are OFF.

Action:

- The operation is automatically resumed if the battery voltage

is over 8.7 ± 0.3 V for 50 ms.

- Check the shift lever connector and power line for contact.

Cause:

The operating current is over 14 ~ 36 A for 50 ms when the backup
lamp is in ON condition.

Symptom: - Backup lamp is OFF.

- Current shift lever indicator is flashing.

- Indicator “R” is flashing in “R” position.

Action:

Check the input and output wirings of backup lamp for open and
short.

Cause:

The  solenoid valve operating current is over 3 ~ 5 A when the
solenoid is operating.

Symptom: - Solenoid valve is OFF.

- Current shift lever indicator is flashing.

Action:

The operation is automatically resumed since the interior tem-
perature is normally within the solenoid operating temperature
range. If the problem stays, check the power to the shift lever.

DIAGNOSIS

TGS LEVER

Open solenoid valve
circuit

Short shift lever
position signal (to B+)

Open or short shift
lever position signal
(to GND)

Abnormal shift lever
position signal

Incorrect shift lever
position sensor coding

Faulty vehicle speed
signal

Faulty CAN bus OFF
signal

Cause:

The  solenoid valve circuit is open or short to battery for 50 ms
when the solenoid valve is OFF.

Symptom: - Solenoid valve is OFF.

- Current shift lever indicator is flashing.

Action:

Check the power terminal to the shift lever.

Cause:

The shift lever position sensor or the power supply is malfunctioning.

Symptom: - All shift lever position indicators are flashing..

- The incorrect lever position signal is transmitted through the

CAN line.

Action:

- The operation is automatically resumed if the fault is not de-

tected for 100 ms.

- Check the power supply terminal to the shift lever.

Cause:

The shift lever position sensor is open or short to ground.

Symptom: - All shift lever position indicators: flashing.

- The incorrect lever position signal is transmitted through the

CAN line.

Action:

- The operation is automatically resumed if the fault is not de-

tected for 100 ms.

- Check the power supply terminal to the shift lever.

Cause:

The shift lever position sensor signal is incorrect.

Symptom: - All shift lever position indicators are flashing.

- The incorrect lever position signal is transmitted through the

CAN line.

Action:

- The operation is automatically resumed if the fault is not de-

tected for 100 ms.

- Check the power supply terminal to the shift lever.

Cause:

The calibration value of shift lever position sensor is not stored or
not consistent with the stored value.

Symptom: - All shift lever position indicators are flashing.

- The incorrect lever position signal is transmitted through the

CAN line.

Action:

- Reset the unit by cyling the ignition switch (OFF 

→ ON) sev-

eral times.

- Check the shift lever and replace it if necessary.

Cause:

The vehicle speed is detected as 300 km/h.

Symptom: - The gear is shifted as for the vehicle speed is 0 km/h.

- Current shift lever position indicator is flashing.

Action:

- The operation is automatically resumed if the fault is not detected.

* For the shift lever, the vehicle speed data is needed to the

solenoid valve operation for R/P lock and N lock function.

Cause:

The  CAN bus OFF condition of the CAN controller is detected
for 3 times in the unit.

Symptom: - Cannot send the CAN message.

- Current shift lever position indicator is flashing.

Action:

- Check the CAN communication line for open or short.

- Check the shift lever and replace it if necessary.

* CAN Bus OFF: The status that the CAN communication is

totally interrupted if there is an error in the sent/received data
through the CAN communication in the unit.
