General Troubleshooting Information (cont’d)
A
1. Connect the HDS to the DLC (A) located under the
driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting
(see page 11-204).
4. Clear the DTC(s) on the HDS screen.
The OBD status shows the current system status of
each DTC and all of the parameters. This function is
used to see if the technician’s repair was successfully
completed. The results of diagnostic tests for the DTC
are displayed as:  PASSED: The on-board diagnosis is successfully completed.
 FAILED: The on-board diagnosis has finished but failed.
 NOT COMPLETED: The on-board diagnosis was running but is out of the enable conditions of the DTC. NOTE: Reset the PCM with the HDS while the engine is
stopped.
1. Turn the ignition switch to LOCK (0).
2. Turn the ignition switch to ON (II), and wait for 30 seconds.
3. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC.
4. Do the PCM idle learn procedure (see page 11-310).
5. Start the engine with the shift lever in P or N, and warm it up to normal operating temperature (the
radiator fan comes on).
6. To verify that the problem is repaired, test-drive the vehicle for several minutes at speeds over 50 km/h
(31 mph) or under the same conditions as those
indicated by the freeze data.
Make sure to follow these points while the vehicle is
raised on a lift for the test-drive.  Disable the VSA by pressing the VSA OFF switch.
 VSA DTC’s may come on when test-driving on a lift. If the VSA DTC(s) come on, clear the DTC(s) with the
HDS.

1. Apply the parking brake, and block both rear
wheels.
2. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
3. Shift to D while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The
engine should not stall.
4. Repeat step 3 in all shift lever positions.
5. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
6. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).7. Prepare the HDS to take a HIGH SPEED SNAPSHOT
(refer to the HDS user guide for more details if
needed):
 Select High Speed icon.
 Select these parameters: – Vehicle Speed
– Output Shaft (Countershaft) Speed (rpm)
– Input Shaft (Mainshaft) Speed (rpm)
– Engine Speed
– APP Sensor A (V)
– ATF Temp Sensor (V)
– Battery Voltage
– Shift Control
– Brake Switch
 Set the Trigger Type to Parameter.
 Adjust the Parameter setting to APP Sensor A above 1.2 V.
 Set the recording time to 60 seconds.
 Set the Trigger point to 30 seconds.
8. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
9. Monitor the HDS and accelerate quickly until the APP Sensor A reads 1.3 V. Maintain a steady
throttle until the transmission shifts to 5th gear,
then slow the vehicle and come to a stop.
10. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 9.
11. Adjust the Parameter setting to 2.4 V. Retest-drive the vehicle. While monitoring the HDS, accelerate
quickly until the APP Sensor A reads 2.5 V.
Maintain a steady throttle until the transmission
shifts to 5th gear (or reasonable speed), then slow
the vehicle and come to a stop.
12. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 11.
13. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the
transmission shifts to 3rd gear, then slow to a stop,
and save the snapshot.

1. Make sure the transmission fluid is filled to the
proper level (see page 14-231).
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
4. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).
5. Make sure the A/C switch is OFF.
6. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
7. Shift to D while pressing the brake pedal firmly, then fully press the accelerator pedal for
6 to 8 seconds, and note the engine speed. Do not
move the shift lever or remove your foot off the
brake pedal while raising the engine speed.
8. Allow 2 minutes for cooling, then repeat the test in SandR.
NOTE: Do not test the stall speed for more than 10 seconds at a time.
 The stall speed tests should be used for diagnostic purposes only.
 Stall speed test results should be the same with the shift lever in D, S, and R.
 Do not test the stall speed with the A/T oil pressure gauges installed. 9. If the stall speeds are out of the service limit, the
problems and probable causes are listed in the
table.

pressure inspection port (A). Do not allow dust or
other foreign particles to enter the ports while
connecting the gauges.
8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
9. Measure the line pressure at the line pressure inspection port with the shift lever in P or N while
holding the engine speed at 2,000 rpm.
NOTE: Higher pressure may be indicated if
measurements are made in shift lever position
other than P or N.
Line 900 960 kPa (9.2 9.8 kgf/cm ,

10. Turn the engine off, then disconnect the A/T oil pressure gauge from the line pressure inspection
port.
11. Install the sealing bolt to the line pressure inspection port with a new sealing washer, and
tighten the bolt to 18 N·m (1.8 kgf·m, 13 lbf·ft). Do
not reuse the old sealing washer.
