NOTESConditions for applying the fault finding procedure to stored faults:
The fault reappears after:
–the ignition is switched on,
–clearing the fault from the memory,
–relay actuated using command AC153 High speed fan assembly.
Special notes:
–the level 1 warning light is illuminated,
–risk of overheating and air conditioning cut-off.
–Use bornier Elé. 1681 for all operations on the connector of the engine management
computer.
–See the Technical Note Wiring Diagrams for the vehicle.
Check the connections of the high-speed fan assembly relay mounting, component code 234.
Check the connections of the engine management computer, component code 120.
If the connector(s) are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s), otherwise replace the wiring.
Run command AC153 High speed fan assembly.
If the command does not work, with the ignition on, check for + 12 V on connection 3FB of component 234
and the earth of connection 3JP of component 234.
Remove the high speed relay and check the continuity of the following connections:
–3FB between components 238 and 234,
–3JP between components 120 and 234.
If the fault is still present, check the relay and replace it if necessary.
If the fault is still present, contact the Techline.

If fault DF024 is present with a C0 or CC.1: the level 2 warning light illuminates and,
depending on the vehicle, the level 1 warning light illuminates with the message
Faulty injection displayed on the instrument panel.
The fuel flow actuator is fully open, there is a clicking, and the engine is stopped
to prevent it from racing.
See the Technical Note Wiring Diagrams for the vehicle.
Check the connection and condition of the flow actuator connector, component code 1105.
Check the connection and condition of connector B (brown 48-track) of the injection computer, component
code 120.
If the connector(s) is 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 for + 12 V after ignition feed on connection 3FB1 or 3FB2 for New Twingo or 3FB3 for Kangoo 2 of
component 1105.

–DF027 Cylinder 2 injector control circuit,
–DF028 Cylinder 3 injector control circuit,
–DF029 Cylinder 4 injector control circuit,

possible to identify the defective injector(s).
Special notes:
When the fault occurs: there is engine noise, the engine speed is unstable, the engine
performance is reduced, and the level 2 warning light comes on with the message
Faulty injection displayed on the instrument panel.
See the Technical Note Wiring Diagrams for the vehicle.
Switch off the ignition, check the condition and connection of the injector connectors, component codes 193,
194, 195, and 196.
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s), otherwise replace the wiring.
Switch off the ignition, disconnect the injectors (or the injector identified by faults DF026 Cylinder 1 injector
control circuit, DF027 Cylinder 2 injector control circuit, DF028 Cylinder 3 injector control circuit,
DF029 Cylinder 4 injector control circuit) and switch on the ignition again.
Using the diagnostic tool, check for changes to fault DF052.
Is DF052 present or stored?
