Move the wiring harness between the injection computer, component code 120 and the battery, component code
107 to see if the status changes (Present Stored).
Look for any damage to the wiring harness and check the connection and condition of the battery, component code
107 and its connections.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Start the engine and check the battery voltage using PR071 Computer supply voltage is X 9V.
Stop the engine and check the charging circuit of the vehicle (see MR 388 (Logan and Sandero), MR 451

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,

Check fuse F03 (for Logan, Sandero, Duster), F4 (for Thalia 2/Symbol 2, Clio II F 6 or F16 (for Kangoo VLL)
and replace it if necessary.
Checking the brake pedal switch:
After the repair, perform these two checks.
With the brake pedal released, check ET039 and ET799.
ET039 must be Released and ET799 must be Inactive.
While depressing the brake pedal, check ET039 and ET799.
ET039 must be Depressed and ET799 must be Active.
The two checks must be correct.
If the fault is still present, contact the Techline.

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
