9.REPLACE POWER STEERING ECU ASSY
NOTICE:
Thoroughly check the procedures for removing and instal-
ling the power steering ECU assy when replacing it. Do the
same operation or procedure for the removing and instal-
ling the steering column assy.
(a)Remove the power steering ECU assy (See page
50±20).
(1) Mark the clamp position on the torque sensor wireharness in order to reinstall the wire harness as
shown in the illustration.
(2) Disconnect the torque sensor wire harness from the
clamp.
NOTICE:
In case the clamp will be reused, pay attention so as not to
damage it. (3) Disconnect the connectors.
(4) LHD:Remove the 2 bolts, screw and power steering ECU
assy.
(5) RHD: Remove the 2 bolts, 2 screws and power steering
ECU assy.

(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.

3.DTC CHECK (SENSOR CHECK)
(a)After the indicator check is completed, the system enters the DTC check mode automatically.
(b)Read the codes displayed on the panel. Refer to the list of codes on page 05±1094 when reading the codes.
(Trouble codes are outputed at the temperature display.)
(c) If the slower display is desired, press the DEF switch and
change it to the stop operation. Each time the DEF switch
is pressed, the display changes by 1 step.
4. CLEARING DTC
(a) To clear diagnostic trouble code, there are 2 ways. (1) During sensor check, press the ºDEFº switch andºDUALº switch at the same time.
(2) Pull the ECU±B2 fuse in fuse block for 20 seconds or longer to clear the DTC memory.
5. CHECK DLC3
(a) The vehicle engine and ECT ECU uses the ISO 9141±2 (Euro±OBD)/ISO 14230 (M±OBD) communication proto-
col. The terminal arrangement of the DLC3 complies with
ISO 15031±3 and matches the ISO 9141±2/ISO 14230
format.
