DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

1) Connect scan tool to DLC with ig nition switch OFF, if available.
2) Clear DTC in TCM memory and start engine.
3) Shift select lever to “D” range and drive vehicle at 50 km /h (31 mile/h) or more with 3rd gear at least for 5 minutes.
4) Stop vehicle and check DTC.

1 Was “A/T System Check” performed? Go to Step 2.Go to “A/T System
Check”.
2 Check input shaft speed sensor circuit
1) Disconnect TCM connectors with ignition switch OFF.
2) Check for proper connection to input shaft speed sensor
at “C35-6” and “C35-16” terminals.
3) If OK, check resistance of sensor circuit.
Input shaft speed sensor specification
Between terminals “C35-6” and “C35-16”: 560 – 680
Ω at 20 °C (68 °F)
Between terminal “C35-6” / “C35-16” and ground: No
continuity
Are check result satisfactory? Go to Step 4. Go to Step 3.

DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

3 Inspect input shaft speed sensor
1) Inspect input shaft speed sensor referring to “Input Shaft
Speed Sensor Inspection”.
Is result satisfactory? “WHT” or “BLK” circuit
open or short.
Replace input shaft
speed sensor.
4 Check visually input shaft speed sensor and direct
clutch drum for the following
• No damage
• No foreign material attached
• Correct installation
Are they in good condition? Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.
Clean, repair or replace.

4) Stop vehicle and check DTC.
DTC Troubleshooting Step Action Yes No 1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check”.
2 Check output shaft speed sensor power circuit
1) Turn ignition switch OFF.
2) Disconnect output shaft speed sensor connector.
3) Turn ignition switch ON.
4) Measure voltage between “BLK/RED” wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is it 10 – 14 V? Go to Step 3. “BLK/RED” wire open or
shorted to ground.
3 Check output shaft speed sensor ground circuit
1) Turn ignition switch OFF.
2) Check continuity between “BLK/ORN” wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is continuity indicated? Go to Step 4. “BLK/ORN” wire open.
4 Check output shaft speed sensor signal circuit for short
1) Disconnect TCM connectors.
2) Check continuity between “PPL” wire terminal of
disconnected output shaft speed sensor harness side
connector and ground.
Is continuity indicated? “PPL” wire shorted to
ground.
Go to Step 5.
5 Check output shaft speed sensor signal circuit for open
1) Check continuity between “PPL” wire terminal of
disconnected output shaft speed sensor harness side
connector and terminal “C35-25” of disconnected
harness side TCM connector.
Is continuity indicated? Go to Step 6. “PPL” wire open.
6 Inspect output shaft speed sensor
1) Inspect output shaft speed sensor referring to “Output
Shaft Speed Sensor Inspection”.
Is check result satisfactory? Go to Step 7. Replace output shaft
speed sensor.
7 Check output shaft speed sensor gears visually
1) Check output shaft speed sensor gears for the
followings.
• No damage in drive gear on differential case
• No damage in driven gear in output shaft speed sensor
Is result satisfactory? Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.Replace drive gear and/
or driven gear of output
shaft speed sensor.
