DIAGNOSIS CODE READING METHOD
There are 55 diagnosis items. The diagnosis code
can be checked using M.U.T.-III.
HOW TO ERASE DIAGNOSIS CODE
MEMORY
Diagnosis code can be erased using M.U.T.-III.
Data list output
The following items input to ASC-ECU can be read
using M.U.T.-III.
NOTE: For service data items, refer to Workshop
Manual.
Actuator test
By forcibly operating the actuator using M.U.T.-III,
the following operations can be performed.
•Forced ABS activation for each wheel
•Forced TCL (brake control) activation for each
wheel
•Forced TCL (engine control) activation
NOTE: .
•When ASC-ECU is disabled, the actuator test
cannot be performed.
•M.U.T.-III uses the ABS data list.
•For the actuator test specification, refer to Work-
shop Manual.
CALIBRATION
When the following operations are performed, the
steering wheel sensor needs to be calibrated using
the M.U.T.-III*.
•Front wheel alignment adjustment
•Steering wheel sensor replacement
NOTE: .
•M.U.T.-III uses the ABS data list.
•*: For calibration, refer to Workshop Manual.
EMISSION CONTROL
ENGINE AND EMISSION CONTROL17-4
GENERAL INFORMATION <4G1>
M2171000100849
Although the emission control systems are basically
the same as those of the 4G1-Non-Turbo engine
used in the COLT, the following improvements have
been added.
•The adoption of the catalytic converter just
beneath turbo charger and under the floor
increased the performance of the emission con
-
trols.
•The adoption of the check valve between the
purge control solenoid valve and the canister pro
-
tects the regurgitation as turbocharging.
