6. Inspection of the SRS-ECU harness connector should be carried out by the following procedure.
Insert the special tool (probe, MB991222, in the harness set) into the connector from harness side
(rear side), and connect the tester to this probe. If any tool than specified is used, damage to the
harness and other components will result. Furthermore, measurement should not be carried out by
touching the probe directly against the terminals from the front of the connector. The terminals are
plated to increase their conductivity, so that if they are touched directly by the probe, the plating
may break, which will cause drops in reliability.

PRECAUTIONS BEFORE SERVICE
LEARNING FUNCTION OF GDI ENGINE
1. Purpose
On the GDI engine equipped cars, when replacement of the ECU (for engine control) or resetting
of the battery* has been performed, an idle learning function of the ECU (for engine control) will
be required.
The idle learning function will be completed by running the engine at idle by the following procedure.
NOTE:
*: Disconnection of ECU (for engine control) battery backup power supply (disconnection of battery
terminals or ECU connectors)
2. Idle Learning Procedure
(1) Start the engine, and warm up the engine until its coolant temperature reaches 85°C or higher.
When the engine coolant temperature is 85°C or higher, you have only to turn the ignition
switch to the ON position.
(2) Turn the ignition switch to the LOCK (OFF) position, and stop the engine.
(3) After lapse of ten or more seconds, restart the engine.
(4) Run the engine at idle for ten minutes under the following conditions.
DTransmission: Neutral (P range for automatic transmission)
DAir conditioner and heater: Not operational
DEngine coolant temperature: 83°C or higher
(5) Stop the engine.
(6) Restart the engine, and run it at idle for ten minutes under the following condition.
DTransmission: Neutral (P range for automatic transmission)
DAir conditioner: Operational (Temperature set at “maximum cool”, fan at high speed, and
windows fully opened)
DEngine coolant temperature: 83°C or higher
(7) Repeat steps (5) and (6).
NOTE:
1) When the atmospheric temperature is 20°C or more and the air conditioner has continuously
been operated, step (7) may be omitted.
2) During idling operation of the engine in steps (4) and (6), when engine operation switches
from lean operation to stoichiometric operation, engine stall can occur. In this case, clean the
throttle body (throttle valve) thoroughly, and then repeat step (1) and the subsequent steps.

GENERAL -Precautions Before Service00-5
PRECAUTIONS BEFORE SERVICE
SUPPLEMENTAL RESTRAINT SYSTEM (SRS), SEAT BELT WITH PRE-TENSIONER
1. Items to follow when servicing SRS
(1) Be sure to read GROUP 52B - Supplemental Restraint System (SRS).
For safe operations, please follow the directions and heed all warnings.
(2) Wait at least 60 seconds after disconnecting the battery cable before doing any further work.
The SRS system is designed to retain enough voltage to deploy the air bag even after the battery
has been disconnected. Serious injury may result from unintended air bag deployment if work
is done on the SRS system immediately after the battery cable is disconnected.
(3) Warning labels must be heeded when servicing or handling SRS components and seat belt with
pre-tensioner. Warning labels are located in the following locations.
DHood
DSun visor
DGlove box
DSRS-ECU
DSteering wheel
DSteering gearbox
DAir bag module (driver’s side and front passenger’s side)
DFront impact sensor
DClock spring
DSeat belt with pre-tensioner
DSide air bag module
DSide impact sensor
(4) Always use the designated special tools and test equipment.
(5) Store components removed from the SRS and seat belt with pre-tensioner in a clean and dry
place.
The air bag module and seat belt with pre-tensioner should be stored on a flat surface and
placed so that the pad surface is facing upward.
Do not place anything on top of it.
(6) Never attempt to disassemble or repair the SRS components (SRS-ECU, air bag module, clock
spring and side impact sensor) and seat belt with pre-tensioner.
(7) Whenever you finish servicing the SRS and seat belt with pre-tensioner, check the SRS warning
lamp operation to make sure that the system functions properly.
(8) Be sure to deploy the air bag and seat belt with pre-tensioner before disposing of the air bag
module and seat belt with pre-tensioner or disposing of a vehicle equipped with an air bag and
seat belt with pre-tensioner. (Refer to GROUP 52B - Air Bag Module and Seat Belt with Pre-tensioner
Disposal Procedures.)
2. Observe the following when carrying out operations on places where SRS components and seat
belt with pre-tensioner are installed, including operations not directly related to the SRS air bag and
seat belt with pre-tensioner.
(1) When removing or installing parts do not allow any impact or shock to the SRS components
and seat belt with pre-tensioner.
(2) SRS components and seat belt with pre-tensioner should not be subjected to heat, so remove
the SRS components and seat belt with pre-tensioner before drying or baking the vehicle after
painting.
DSRS-ECU, air bag module, clock spring, front and side impact sensors: 93_C or more
DSeat belt with pre-tensioner: 90_C or more
After re-installing them, check the SRS warning lamp operation to make sure that the system
functions properly.

METHOD OF READING AND ERASING DIAGNOSIS
CODES
Refer to GROUP 00 - How to Use Troubleshooting/Inspection
Service Points.
DIAGNOSIS USING DIAGNOSIS 2 MODE
1. Switch the diagnosis mode of the engine-A/T-ECU to
DIAGNOSIS 2 mode using the MUT-II, and then carry
out a road test.
2. Take a reading of the diagnosis code and repair the
problem location.
3. Turn the ignition switch to the LOCK (OFF) position, and
then back to ON again.
NOTE
By turning the ignition switch to the LOCK (OFF) position,
the engine-A/T-ECU will switch the DIAGNOSIS 2 mode
to DIAGNOSIS 1 mode.
4. Erase the diagnosis codes.
INSPECTION USING MUT-II
DATA LIST AND
ACTUATOR TESTING
1. Carry out inspection by means of the data list and actuator
test function. If there is an abnormality, check and repair
the chassis harnesses and components.
2. After repairing, re-check using the MUT-IIand check that
the abnormal input and output have returned to normal
as a result of the repairs.
3. Erase the diagnosis code memory.
4. Remove the MUT-II, and then start the engine again and
carry out a road test to confirm that the problem has
disappeared.
