DIAGNOSIS FUNCTION
The SRS-ECU has the following functions to make
system check using M.U.T.-III easy.
•Diagnosis code set
•Service data output

NOTE: .
•*1: Electrically Erasable Programmable ROM
•*2: This diagnosis code memory will be automatically cleared from the memory and the SRS warning
lamp will be switched off when the system returns to normal condition.
•*3: The diagnosis codes will remain in memory and the SRS warning lamp will be switched off if the sys-
tem returns to normal condition.
SERVICE DATA OUTPUT
When the SRS-ECU detects a problem, it stores a
diagnosis code and the duration that the problem has
lasted in the non-volatile memory. In addition, how
often a diagnosis code and duration are cleared by
the M.U.T.-III are stored in the non-volatile memory
as a reference for service work. This data can be
read by the M.U.T.-III.

GENERAL
ACTIVE STABILITY CONTROL SYSTEM (ASC)35C-2
GENERAL
M2357000200040
The active stability control system (ASC) has been
installed to the M/T vehicle.
•The active stability control system (ASC) has the
stability control and the traction control (TCL)
functions. By the integrated control with the
anti-lock brake system, the system stabilises the
vehicle attitude and at the same time secures the
driving force.
•When the stability control function determines
that the vehicle is in a dangerous condition, it
reduces the engine output and applies brake
force to four wheels independently to control the
vehicle behaviour, avoiding the critical state.
•The traction control (TCL) function prevents the
driving wheel slip on a slippery road surface,
ensuring easy startup, and at the same time,
secures proper driving force and improves steer
-
ing performance during cornering acceleration.
•Fail-safe function assures the security.
•Serviceability improvement
•For wiring harness saving and secure data com-
munication, the CAN* communication has been
adopted as a tool of communication with another
ECU.
NOTE: .
•*For more information about CAN (Controller
Area Network), refer to GROUP 54C
P.54C-2.
•ABS and ASC are controlled by ASC-ECU.

Example of TCL control
When th e driving wheel slip s (ex. during drivin g on
low
µ road), TCL send s the engine out put red u ction
sign
al to the en gine ECU in order to prevent th e driv
-
ing f o r c e loss cau s e d by t he dr iving whe e l slip . A t t h e
same time, TCL a
pplies th e brake to t he slipp i ng
driving whe
e l so that the drivin g force is applied to
t
he non-slipping driving wheel, which co ntrols the slip
o
f th e drivi ng wheel, securin g the prop er d r iving f o rce
and increa
sed steering fo rce.
Fail-safe and diagnostic functions
ASC-ECU constantly mo nitors the input and ou tput
sign
als. If an error is det ected in th e syste m ,
ASC-ECU send

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.
