NOTESSpecial notes:
Only perform the tests if the statuses do not correspond with the system programming
functions.
Note:
Statuses ET704 and ET705 should change status at the same time. If they are inconsistent, consult the
interpretation of fault DF228 Brake signal.
ACTIVE
or
INACTIVEIf the brake lights are working, check the continuity and the absence of interference
resistance between the following connections:
Brake light switch, track 3 Injection computer, connector A,
black, 32-track track E4
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Repair precautions), repair the wiring, otherwise replace it.
If the brake lights are not operational, check:
– the condition and fitting of the brake switch,
– the condition and conformity of the brake light fuse,
– the conformity of the values in the following table:
Continuity between
tracksInsulation between
tracks
Switch pressed
(Brake pedal released)3 and 4 1 and 2
Switch released
(brake pedal pressed)1 and 2 3 and 4
Replace the switch if the values obtained are not correct.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

Test the diagnostic tool on another vehicle in perfect working order.
Check that the sensor's green indicator light comes on.
Communication with the second vehicle is impossible, follow the instructions in the CLIP diagnostic tool check
section.
If you establish dialogue with the second vehicle, follow the instructions in the Vehicle check section.

CHECK
Check the cleanliness and condition of the diagnostic socket contacts which
connect to the vehicle.
Check the condition of the cable from the diagnostic socket to the sensor, and the
cleanliness and condition of the connections.
Check the sensor connections.
Check the condition of the cable from the sensor to the CLIP tool, and the
cleanliness and condition of the connections.
Check the cleanliness and condition of the CLIP socket.
If the fault is still present, contact Techline.
Check the electrical voltage of the battery.
Check the cleanliness and condition of the battery terminals.
Check the condition and tightness of the cable going from the battery + terminal to
the Protection and Switching Unit.
Check the condition of the battery earth cable and ensure that there is a good
electrical connection with the bodywork.
Check the injection computer earth terminal for cleanliness and make sure it is
properly connected to the bodywork.
Check the Protection and Switching Unit's main 30A power supply fuse, plus the
condition and cleanliness of the contacts (see Protection and Switching Unit fault
finding).
Check the injection computer after ignition feed 5A fuse, plus the condition and
cleanliness of the contacts.
AFTER REPAIRRepeat the conformity check from the start.
