statuses ET043 "Lever contact No. 0", ET044 "Lever contact No. 1", ET045 "Lever contact No. 2" and
ET046 Lever contact No. 3").
Repair if necessary.
Check for the presence and condition of the brake light switch supply fuse on the passenger compartment fuse
board.
Repair if necessary.
Check that the brake light switch connector is correctly connected, check the condition of the connections as well
as those of the computer.
If the connectors are faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the connectors; otherwise, replace the wiring.
Check that the brake light switch on the pedal is correctly fitted and adjusted.

component 160.
Replace the switch if necessary (see MR 411 Mechanical, 83D Cruise control, Brake light switch: Removal -
Refitting).
Check there is no continuity with the pedal released, between connections AP10 (track 2) and 65A of
component 160.
Replace the switch if necessary (see MR 411 Mechanical, 83D Cruise control, Brake light switch: Removal -
Refitting).
If the fault is still present, check the continuity of the following connection:
●Connection code 65A between components 160 and 119.
Also ensure the insulation to earth.
AFTER REPAIRClear the computer fault memory. Switch off the ignition and wait 20 seconds.
Carry out a road test followed by another check with the diagnostic tool.

NOTESSpecial notes:
Only consult this customer complaint after a complete check with the diagnostic tool.
–The buzzer is active:
–when the front doors are opened,
–if the clutch overheats while the vehicle is being driven,
–if the sequential gearbox programming has not been carried out.
