When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and condenser, thus resulting in dam-
age to ICs.
Keep engine control system harness at least 10 cm (4 in) away
from adjacent harness, to prevent engine control system mal-
functions due to receiving external noise, degraded operation
of ICs, etc.
Keep engine control system parts and harness dry.
Before replacing ECM, perform ECM Terminals and Reference
Value inspection and make sure ECM functions properly.
Refer to EC-990, "
Reference Value".
Handle mass air flow sensor carefully to avoid damage.
Do not clean mass air flow sensor with any type of detergent.
Do not disassemble electric throttle control actuator.
Even a slight leak in the air intake system can cause serious
incidents.
Do not shock or jar the camshaft position sensor (PHASE),
crankshaft position sensor (POS).
After performing each TROUBLE DIAGNOSIS, perform DTC
CONFIRMATION PROCEDURE or Component Function
Check. The DTC should not be displayed in the DTC Confirmation
Procedure if the repair is completed. The Component Function
Check should be a good result if the repair is completed.

DIAGNOSIS AND REPAIR WORKFLOW
 Malfunctions are declared as either present or stored (depending on whether they appeared in a certain con-
text and have disappeared since, or whether they remain present but have not been diagnosed within the
current context).
 The present or stored status of malfunctions should be taken into consideration when the diagnostic tool is
used following the + after ignition supply being switched on (without acting on the system components).
 For a present malfunction, apply the procedure described in the Interpretation of malfunction section.
 For a stored malfunction, note the malfunctions displayed and apply the instructions in the Notes section.
 If the malfunction is confirmed when the instructions in the Notes section are applied, the malfunction is
present. Deal with the malfunction
 If the malfunction is not confirmed, check:
- the electrical lines which correspond to the malfunction,
- the connectors for these lines (for oxidation, bent pins, etc),
- the condition of the wires (insulation has melted or been cut, abrasions),
- the resistance of the component detected as malfunction.
Conformity Check
 The aim of the conformity check is to check data that does not produce a malfunction on the diagnostic tool
because the data is inconsistent. Therefore, this phase is used to:
- carry out malfunction finding on malfunctions that do not have a malfunction display, and which may corre-
spond to a customer complaint.
- check that the system is operating correctly and that there is no risk of a malfunction recurring after repairs.
 This section gives the malfunction finding procedures for statuses and parameters and the conditions for
checking them.
 If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the cor-
responding malfunction finding page.
Customer Complaints - Malfunction finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the malfunction should be
processed by customer complaint.
NOTE:
A synopsis of the general procedure to follow is provided on the preceding page in the form of a flow
chart.
Malfunction Finding Procedure (Wiring Check)
Diagnostics malfunctions
Removing the connectors and/or handling the wirings may temporarily remove the origin of a DTC. The mea-
surements of the electrical voltages, resistance and insulation are generally correct, especially when the DTC
is not present at the time of the analysis (stored DTC).
Visual Check
Look for impacts under the bonnet and in the passenger compartment.
Perform a careful check of the protections, insulation and correct running of wirings.
Look for traces of oxidation.
Tactile Check
While manipulating the wirings, use the diagnostic tool to detect a change in DTC status from “stored” to
“present”.
Ensure that the connectors are correctly engaged.
Apply light stresses to the connectors.
Gently manipulate the wiring harness.
If a change of status occurs, try to isolate the origin of the incident.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and blades and their crimping (no crimping
on the insulating part).
Check that the clips and blades are properly engaged in the receptacles.
Ensure that there is no rebounding of clips or blades at the time of connection.
Check the contact pressure of the clips using a suitable model blade.
Resistance Control
Test the continuity of the lines in their entirety, then section by section.
Try to create a short-circuit to earth, on the + 12 V or with another wire.
If a DTC is detected, repair or replace the wiring.

There are present DTCs and stored DTCs (which appeared in a certain context and have since disappeared
or which are still present but have not had trouble diagnosis performed on them in the current context).
The “present” or “stored” status of DTCs must be considered when activating the diagnostic tool after power is
supplied to the ECM (without activating the system components).
Deal with present DTCs according to the procedure specified in the corresponding DTC trouble diagnosis.
For stored DTCs, note the DTCs displayed and follow the instructions in the Notes section.
If the DTC is confirmed when the instructions in the Notes section are applied, the malfunction is present. Deal
with the DTC.
If the DTC is not confirmed, check: Electrical lines which correspond to the malfunction
 Connectors for these lines (for oxidation, bent pins, etc.)
 Resistance of the malfunction component
 Condition of the wires (melted or cut insulation, wear)
Conformity Check
The conformity check is designed to check the states and data monitor items which do not display any DTCs
on the diagnostic tool when inconsistent. This phase therefore allows:
 Diagnoses malfunctions that do not have a DTC display, and which may correspond to a customer com-
plaint.
 Checks that the system is operating correctly and that there is no risk of a DTC reappearing after repairs.
This section gives the trouble diagnosis procedures for states and parameters and the conditions for checking
them.
If a state is not operating normally or a data monitor value is outside permitted tolerance values, you should
consult the corresponding trouble diagnosis page.
Customer Complaints - Trouble Diagnosis
If the test with the CONSULT-III is OK, but the customer complaint still present, the malfunction should be
treated by customer complaints.
SAFETY ADVICE
 The safety instructions must be followed at all times when working on components, to avoid damage or
injury:
- make sure that the battery is properly charged to avoid damaging the computers with a low load,
- use the appropriate tools,
- do not touch the xenon bulbs.
Diagnostic Work SheetINFOID:0000000001162513
DESCRIPTION
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about a incident. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the one on the next page in order
to organize all the information for troubleshooting.
Some conditions may cause the MI to come on steady or blink and
DTC to be detected. Examples:
 Vehicle ran out of fuel, which caused the engine to misfire.
 Fuel filler cap was left off or incorrectly screwed on, allowing fuel to
evaporate into the atmosphere.A synopsis of the general procedure to follow is pro-
vided on the previous page in the form of a flow
chart.

< FUNCTION DIAGNOSIS >[K9K]
FUEL INJECTION CONTROL
energy returned by the piezo actuator is reused, which keeps down the amount of energy that has to be sup-
plied for the next injection process.
Engine Synchronisation
One of the determining factors for fuel injection control is knowing the position of each of the pistons in their
respective cylinders at all times.
The angular position is measured by means of a magneto-inductive sensor which is excited by the teeth
machined onto the flywheel; this is known as the crankshaft position sensor. The flywheel has 60 teeth, each 6
degrees apart; 2 of these teeth are missing to form a notch.
A second sensor (Hall-effect sensor), stimulated by a tooth machined onto the camshaft, which turns at half
the engine speed, provides a signal relating to the progress of the injection cycle. Indeed, when the piston of
cylinder 1 is at top dead centre (TDC), either at the end of the compression stroke or at the end of the exhaust
stroke, the camshaft position sensor enables a distinction to be made between these two states.
By comparing the signals from these two sensors, the computer is able to provide all its systems with synchro-
nisation parameters, namely: the angular position of the flywheel, engine speed, the number of the active fuel
injector and the progress of the injection cycle.
This module also supplies the system with the rotation speed signal.
The camshaft position sensor is only used when starting the engine. As soon as the engine is running by itself
(not being cranked by the starter), the signal provided by the crankshaft position sensor is sufficient. If the
camshaft position sensor should fail while the engine is running, this will not affect the operation of the engine.
Quantity of Fuel Injected and Control of Start of Injection
 The parameters for controlling injection are, for each cylinder, the quantity to be injected and the start of
injection. These are calculated by the ECM from the following information:
- Engine speed.
- Accelerator pedal position.
- Turbocharge air pressure.
- Engine coolant temperature.
- Intake air temperature.
- Fuel pump temperature.
- Mass air flow.
- Pressure of fuel in the rail.
Station to Station Flow Regulation
The aim of this regulation process is to facilitate smooth engine operation by compensating for the system
variations (fuel injectors, compression rate, etc.) which affect the torque generated by each cylinder during
combustion.
The regulation process is only active at idle speed, with a warm engine and on condition that the engine speed
is sufficiently stable. An injection timing correction coefficient is assigned to each cylinder; this is "learning" all
the time the regulation process is active and remains fixed at the last value that was learned when the regula-
tion is inactive.
At each new cycle, the coefficients are initialised to 1.
Cylinder Balancing Control
This controller allows smooth behavior of running engine, reduction of noise and oscillations in the drivetrain
by compensating for system dispersions (fuel injectors, compression ratio, manufacturing tolerances of cylin-
ders or valves...) having an influence on the torque generated by each cylinder during combustion.
The controller is only activated if engine is in idle, warm and not too rough. Corrective coefficient on the injec-
tion time is associated with each cylinder that is learnt as soon as the regulation is active. Otherwise it remains
with its last memorized value.
At each new driving cycle, coefficients are initialized to 1.

PRECAUTIONS
General Precautions
INFOID:0000000001162746
Always use a 12 volt battery as power source.
Do not attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF, wait 3 minutes and discon-
nect battery negative cable. Failure to do so may damage the
ECM because battery voltage is applied to ECM even if igni-
tion switch is turned OFF.
Before removing parts, turn ignition switch OFF and then dis-
connect battery negative cable.
Do not disassemble ECM.
When connecting ECM harness connector, fasten (A) it
securely with levers (1) as far as they will go as shown in the
figure.
-ECM (2)
-Loosen (B)
When connecting or disconnecting pin connectors into or
from ECM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on ECM pin
terminal, when connecting pin connectors.
Securely connect ECM harness connectors.
A poor connection can cause an extremely high (surge) volt-
age to develop in coil and condenser, thus resulting in dam-
age to IC's.
Keep engine control system harness at least 10cm (4 in) away
from adjacent harness, to prevent engine control system mal-
functions due to receiving external noise, degraded operation
of IC's, etc.
Keep engine control system parts and harness dry.
Handle mass air flow sensor carefully to avoid damage.
Do not disassemble mass air flow sensor.
Do not clean mass air flow sensor with any type of detergent.
Even a slight leak in the air intake system can cause serious incidents.
Do not shock or jar the camshaft position sensor, crankshaft position sensor.
