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.

INSPECTION PROCEDURE
NOTICE:
When performing the inspection of power steering ECU, ECU must be instal\
led to the vehicle or fully
fixed.
HINT:

tester.
1READ VALUE OF HAND±HELD TESTER
(a)Connect the hand±held tester to the DLC3.
(b)Turn the ignition switch to ON and turn the hand±held tester main swit\
ch to ON.
(c)Select the item ºPIG SUPPLYº in the FREEZE FRAME DATA and read its value displayed on the hand±
held tester.
(d)Check that the power supply voltage value of the drive motor displayed b\
y the hand±held tester. Standard:
Voltage: 10 to 16 V
OKGo to step 3
