NOTESConditions for application to a stored fault:
The fault is declared present after the ignition has been switched on or after running
command AC038 Low speed fan assembly relay
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Run command AC038 and check the supply of the low speed fan assembly relay control circuit, component code
784, using a test light on connection 3JN of component 120.
Check the connection and condition of the connector of the injection computer, component code 120 and of the
low speed fan assembly relay, component code 784.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation, continuity and check for absence of interference resistance on the following
connection:
–3JN between components 784 and 120.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Run command AC038 and check the supply of the low speed fan assembly relay power circuit using a test light on
connection BP7 of component 784.
If the check is not correct, replace the fan assembly control relay, component code 784.
If the fault is still present, contact the Techline.

STOREDBRAKE SWITCH CIRCUIT
1.DEF: Inconsistent signal.
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is present after the ignition has been switched on and the brake pedal has
been depressed.
The fault appears after a fault on one of the two brake switch contacts.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
With the brake pedal released, check ET039 Brake pedal and ET799 Brake wire contact.
ET039 must be Released and ET799 Inactive.
Check the fitting and mechanical operation of the brake pedal (the pedal returns properly).
If the check is incorrect, check the braking system.
Remove the brake pedal switch, component code 160 (see MR 388 (Logan and Sandero), MR 451 (Duster), MR
423 (Thalia 2/Symbol 2), Mechanical, 37A, Mechanical component controls, Brake pedal switch: Removal
- Refitting or MR 430 (Clio II F 6), MR 374 (Kangoo VLL), Mechanical, 37A, Mechanical component controls,
Brake pedal: Removal - Refitting) and, without depressing the pedal, press sufficiently on the brake pedal switch
to seat it completely in its position.
Lock it by turning it an eighth of a turn.
With the brake pedal depressed, measure the resistance of the brake pedal switch, component code 160 between
connections AP1 (for Logan, Sandero, Duster) or AP10 (for Thalia 2/Symbol 2, Clio II F 6, Kangoo VLL) and
65A. The value must be X > 10 M (between 0°C and 40°C).
If the resistance is not correct, replace the brake pedal switch, component code 160 (see MR 388 (Logan and
Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), Mechanical, 37A, Mechanical component controls,
Brake pedal switch: Removal - Refitting or MR 430 (Clio II F 6), MR 374 (Kangoo VLL), Mechanical, 37A,
Mechanical component controls, Brake pedal: Removal - Refitting).
With the brake pedal released, measure the resistance of the brake pedal switch, component code 160 between
connections AP1 (for Logan, Sandero, Duster) or AP10 (for Thalia 2/Symbol 2, Clio II F 6, Kangoo VLL) and
5A, the value must be between 0 < X 1 (between 0°C and 40°C).
If the resistance is not correct, replace the brake pedal switch, component code 160 (see MR 388 (Logan and
Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), Mechanical, 37A, Mechanical component controls,

1.DEF: Polluting misfiring
2.DEF: Destructive misfiring
NOTESPriority when dealing with a number of faults:
– DF109 Low fuel level misfire,
Check whether there are other cylinders with a combustion misfire fault reported by
the diagnostic tool before starting the fault finding procedure below.
Conditions for applying the fault finding procedure to a stored fault:
The fault is considered present under the following conditions:
– engine running at idling speed.
Special note:
OBD warning light comes on.
1.DEF
NOTESNone.
Check the ignition coil circuit (see MR 388, Mechanical, 17A, Ignition, Ignition: Specifications),
Check the fuel supply circuit (see MR 388 (Logan and Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol
2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 13A, Fuel supply, Fuel circuit: Operating
diagram),
Check the fuel supply pump circuit,
Check the condition of the cylinder 1 injector (see MR 388 (Logan and Sandero), Mechanical, 13A, Fuel supply,
Injector rail - Injectors: Removal - Refitting, MR 451 (Duster) or MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II
F 6), MR 374 (Kangoo VLL), Mechanical, 17B, Petrol injection, Injector rail - Injectors: Removal - Refitting),
Check the compression of cylinder 1.
After repair, check that the catalytic converter was not damaged by the misfire.
To do this, switch on the ignition, run the catalytic converter test SC006 Run OBD test: Catalytic converter and
start the engine (only depress the brake pedal to authorise the starting of the engine,
do not touch the accelerator pedal or clutch pedal).
At the end, check the test results:
STATUS1: Fault finding was not performed/impossible to obtain the necessary conditions
STATUS2: The component is in an average condition - sensor OK
STATUS3: The component is in a good condition - sensor OK
STATUS4: The component is in poor condition - replace the catalytic converter (see MR 388 (Logan and
Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL),
