6.INPUT SIGNAL CHECK (TEST MODE)
(USING HAND±HELD TESTER)
(a)Check the input signal using the hand±held tester.
(1)Connect the hand±held tester to the DLC3.
(2)Check that the warning light goes off with driving thevehicle more than 10 km/h (6 mph) and engine
speed more than 300 rpm.
(3)Read the DTC by following the prompts on the tes- ter screen.
HINT:

Refer to the hand±held tester operator's manual for fur-
ther details.

See the list of DTC shown in the table below.

Even if a sensor is normal, it outputs codes C1571/71 and
C1573/73 during test mode.
DTC of input signal check function:

(b) Perform the torque sensor zero point initialization.
HINT:
If the power steering ECU assy is replaced, initialization is not
necessary.
(1) Stop the vehicle.
(2) Connect the hand±held tester to the DLC3.
(3) Select the ºTRQ SENS ADJUSTº mode on the
hand±held tester.

(4) Align the marks on the torque sensor wire harness
with the clamp, as shown in the illustration.
NOTICE:

When reusing the clamp, check that there is no dam-
age on it.

When reinstalling the wire harness, make sure there
is no twist in the harness or with other wire harness.
10. FAIL SAFE FUNCTION
(a) If the power steering ECU assy detects a trouble, the ECU
assy halt, fix or lower the steering power assist in order to
protect the system.
HINT:
Repeating the steering operation when stopping or driving at
low speed, or leaving the steering wheel turn fully for long hours
will lower the amount of power assist in order to prevent power
steering ECU assy from heating up. In this case, not operating
the steering for about 10 minutes with engine idle will lead the
fail safe function to return the normal state.
