1) Connect scan tool to DLC with ignition 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 vehicle speed at least for 3 minutes.
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.

WARNING!
• When taking warmed final driven gear out of vessel, use tongs or the like. Taking out
it with bare hand will cause severe burn.
• While installing warme d final driven gear,
use oven glove such as leather glove.
Picking up it with bare hand may cause
burn.

CAUTION!
Do not leave final driven gear in boiling water
for longer than 5 min. Overheating the gear
may cause strength reduction of gear.

1) Put final driven gear in water vessel, heat and remove when it boils, then remove moisture.
NOTE
After removing moisture on final driven gear,
install final driven gear to differential case as
