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.

EPS IndicatorDiagnostic Trouble Code (DTC)
Self-diagnosis
17-19
General Troubleshooting Information
Under normal conditions, the EPS indicator comes on
when the ignition switch is turned to ON (II), then goes
off after the engine is started. This indicates that the
LED and its circuit are operating correctly.
If there is a failure in the system after the engine is
started, the EPS indicator will stay on, and the power
assist is turned off or restricted.
When the EPS indicator comes on, the control unit
memorizes the DTC. In this case, the control unit will
not activate the EPS system after the engine starts
again, but it keeps the EPS indicator on.
When DTC 51-01, 51-02 or 51-06 is stored in the control
unit, the EPS indicator will stay on until the DTC is
erased. When a problem is detected and the EPS
indicator comes on, there are cases when the indicator
stays on until the ignition switch is turned to LOCK (0),
and cases when the indicator goes off automatically
when the system returns to normal. Even though the
system is operating normally, the EPS indicator will
come on under the following conditions:  The vehicle speed decreases abruptly from 20 km/h (12 mph) or more (by applying brake), and it is less
than 1 km/h (1 mph) and engine speed is 2,000 rpm or
above for 5 seconds (continuously) after the abrupt
deceleration.
 While turning the steering wheel with the vehicle speed of 1 km/h (1 mph) or less for 20 seconds, and
the engine speed is 2,000 rpm or above for at least
10 seconds.
 When the engine speed is 500 rpm or less, and the vehicle is traveling at a speed of 10 km/h (6 mph) or
more for about 3 seconds.
To determine the actual cause of the problem, question
the client about the conditions during which the
problem occurred, taking the above conditions into
consideration.  If the CPU cannot be activated, or it fails, the EPS
indicator comes on, but the DTC is not memorized.
 The memory can hold any number of DTCs. However, when the same DTC is detected more than once, the
most recent DTC is written over the prior DTC,
therefore only one occurrence is memorized.
 The lowest DTC is indicated first. The DTCs are indicated in ascending order, not in the order that
they occurred.
 The DTCs are memorized in the EEPROM (non- volatile memory) therefore the memorized DTCs
cannot be erased by disconnecting the battery. Do the
specified procedures to clear the DTCs.
Self-diagnosis can be classified into three categories:  Initial diagnosis: Done right after the engine starts and until the EPS indicator goes off.
 Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned to LOCK
(0).
 Steering diagnosis: Done during regular diagnosis while turning the steering wheel.
The EPS control unit dose these functions when a
problem is detected by self-diagnosis: 1. Turns on the EPS indicator.
2. Memorizes the DTC.
3. Stops power assist and manual steering operation resumes.
NOTE: For DTCs 11-01, 11-02, 12-01, 21-01, 21-02,
22-01, and 35-04 the EPS indicator will go off
automatically, and the system returns to normal.
