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.
