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.

Restriction on Power Assist Operation
Torque Sensor Neutral PositionHow to Troubleshoot DTCs
17-20EPS Components
General Troubleshooting Information (cont’d)
Repeated extreme steering force, such as turning the
steering wheel continuously back-and-forth with the
vehicle stopped, causes an increase of power
consumption in the EPS motor. The increase of electric
current causes the EPS motor to heat up. Because this
heat adversely affects the system, the control unit
monitors the electric current of the EPS motor.
When the control unit detects heat build-up in the EPS
motor, it reduces the electric current to the EPS motor
gradually to protect the system, and it restricts the
power assist operation. The EPS indicator does not
come on during this function.
When steering torque is not applied to the steering
wheel, or when the ignition is turned to LOCK (0) and
the EPS motor cools, the control unit will restore the
power assist gradually until it’s fully restored (after
about 8 minutes).
The EPS control unit stores the torque sensor neutral
position in the EEPROM. The torque sensor neutral
position must be memorized whenever the gearbox, the
EPS motor, or the EPS control unit is replaced.
NOTE: The torque sensor neutral position is not
effected when erasing the DTCs.
The troubleshooting procedures assume that the cause
of the problem is still present and the EPS indicator is
still on. Following the procedure when the EPS
indicator does not come on can result in incorrect
diagnosis.
1. Question the client about the conditions when the problem occurred, and try to reproduce the same
conditions for troubleshooting. Find out when the
EPS indicator came on, such as while turning, after
turning, when the vehicle was at a certain speed,
etc.
2. When the EPS indicator does not come on during the test-drive, but troubleshooting is done based on
the DTC, check for loose connectors, poor terminal
contact, etc., in the affected circuit before you start
troubleshooting.
3. After troubleshooting, clear the DTC and test-drive the vehicle. Be sure the EPS indicator does not
come on.
