DIAGNOSTIC TROUBLE CODES FOR ION (BTRA) AUTO
TRANSMISSION

Cause:

- Gear position sensor signal of the inhibitor switch is lower than

the normal value (defective gear position sensor)

- Specified value of gear position sensor signal: 0.87 V

Symptom: - Cannot shift to 1st, 3rd and 4th gear.

- Torque converter clucth stops from its operation.

Action:

- Check gear position sensor for short to ground.

- Check inhibitor switch and TCU connector for proper connection.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 30 seconds.

Cause:

- Gear position sensor signal of the inhibitor switch is higher

than the normal value (defective inhibitor switch)

- Specified value of inhibitor switch: 4.12 V

Symptom: - Cannot shift to 1st, 3rd and 4th gear position.

- Torque converter clucth stops from its operation.

Action:

- Check gear position sensor for short to B+.

- Check inhibitor switch and TCU connector for proper connection.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 30 seconds.

Defective

Cause and Action

P0707

P0708

Cause:

- Torque  conver clutch cannot be engaged even when solenoid

valve (S7) is operated.

- The rpm of engine and output shaft is not consistent with the

selected shift's gear ratio.

• Allowable slip rpm of torque converter:100 rpm

Symptom: - Torque converter clutch cannot be locked

Action:

- Check solenoid valve (S7) wiring for short to ground or open circuit.

- Replace solenoicd valve (S7) if necessary.

- Check T/M connector TCU connector for their proper connection.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 30 seconds.

DIAGNOSIS

TCU

Cause:

- Torque  conver clutch is engaged when solenoid valve (S7) is

not operated.

- The rpm of engine and output shaft is not consistent with the

characteristic under the condition with torque converter not
engaged.

• Allowable slip rpm of torque converter < 50 rpm

Symptom: - Torque converter clutch is locked.

Action:

- Check solenoid valve (S7) wiring for short to B+.

- Replace solenoicd valve (S7) if necessary.

- Check T/M connector TCU connector for their proper connection.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 30 seconds.

Cause:

- Oil temperature of T/M exceeds the specified value.

• Oil temperature sensor voltage > 4.88 V

• Oil temperature sensor voltage < 0.21 V

Symptom: - Oil temperature is fixed to 120°C

- Shifting impression is poor.

Action:

- Check T/M oil temperature sensor for short or open circuit.

- Check T/M connector and TCU connector for proper connection.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 3 seconds.

Cause:

- The  W/N/P mode switch's connection is intermittently discon-

nected (the input of the mode switch changes rapidly).

Symptom: - The switch is fixed to normal mode.

Action:

- Check W/N/P mode switch input circuit for short or open circuit.

- Check W/N/P mode switch wiring.

- Replace W/N/P mode switch if necessary.

- Returns to the normal operation if the failure does not occur

within 3 seconds.

CCCS

Cause:

- The engine rpm signal (CAN) is out of specified value or there is

no engine rpm signal.

• Engine rpm < 0 rpm

• Engine rpm > 7000 rpm

Symptom: - The engine rpm corresponding to the max. engine torque is

applyed to the shifting condition.

Action:

- Check ECU and TCU connectors for poor contact.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 3 seconds.

Cause:

- The output shaft signal (CAN) is out of specified value or there

is no output shaft signal.

• Output shaft rpm < 0 rpm

• Output shaft rpm > 9000 rpm

- The actual vehicle speed is 0 while other signals indicate that

vehicle is moving.

Symptom: - Cannot shift down by limiting the engine rpm to prevent the

engine from overrunning.

Action:

- Check ECU and TCU connectors for poor contact.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 3 seconds and the rpm is over 0.

Cause:

- The TCU supply voltage is low or there is no measured voltage

value.

Symptom: - Cannot shift to 1st gear position.

- Cannot shift to other gear positions due to the low supply voltage.

- No. 6 solenoid valve (S6) stops from its operation.

Action:

- Check TCU terminal for poor contact, bending or deformation.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 30 seconds.

Cause:

- The TCU supply voltage is high.

• TCU supply voltage > 16.5 V

Symptom: - All solenoid valves stop from their operation when high battery

voltage is detected.

- Enters into the emergency mode.

Action:

- Check TCU terminal for short to B+ or short to ground.

- Replace TCU if necessary.

- Returns to the normal operation if the failure does not occur

within 30 seconds.
