NOTESSwitch on the vehicle + after ignition feed.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present if the battery voltage is X < 3.5 V after 5 voltage checks.
Check the voltage and the battery connections, component code 107.
Repair if necessary.
If the fault is still present and the internal battery is currently charging, wait for approximately 2 hours so that the
internal battery voltage is X > 3.5 V.
If the fault is still present, replace the anti-theft tracking unit, component code 2186 (see MR 388, 451, 364, 370,
377, 423, 430 or 374, Mechanical, 82A, Immobiliser, Tracking unit: Removal - Refitting).
If the fault is still present, contact the Techline.

Use the Wiring Diagrams Technical Note for LOGAN, SANDERO, DUSTER,
MEGANE II ph1 and ph2, SCENIC II, MASTER II ph2 and ph3, THALIA 2/SYMBOL
2, CLIO II F6, KANGOO VLL.
Ensure that the diagnostic tool is not the cause of the fault by using it to establish dialogue with a
computer on another vehicle. If the diagnostic tool is not causing the fault and dialogue cannot be established
with any other computer on the same vehicle, it may be that a faulty computer is disrupting the fault finding line.
Use a process of successive disconnections to locate this computer.
Check the battery voltage, component code 107, and perform the necessary operations to obtain the correct
voltage (12 V < X < 15 V).
Check the condition of the fuses in the passenger compartment fuse and relay box, component code 260 for
MEGANE II ph1 and ph2, SCENIC II, KANGOO VLL or component code 1016 for LOGAN, SANDERO, DUSTER,
MASTER II ph2 and ph3, THALIA 2/SYMBOL 2, CLIO II F6.
Check the connection of the anti-theft tracking unit connector, component code 2186.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.

For MEGANE II and SCENIC II, check the connection of the Protection and Switching Unit connector, component
code 1337.
If the connector is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
For CLIO II F6, check the connection of the UCH connector, component code 645.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the continuity, insulation and the absence of interference resistance on the following connections:
