NOTESPriorities when dealing with a number of faults:
If DF069 Selection position sensor circuit and/or DF070 Engagement position
sensor circuit is stored, deal with them first.
Special notes:
Fault warning light comes on.
Improper use of lever when the vehicle is stationary may lead to this fault.
Check that the selector lever is correctly clipped onto the hydraulic unit by looking through the inspection flap
(see MR 411 Mechanical, 21B, Sequential gearbox).
Check if the water in the gearbox oil is due to condensation.
Replace the oil if necessary (see MR 411 Mechanical, 21B, Sequential gearbox, Electric pump assembly oil:
Specifications).
If it is difficult to select gears, especially reverse gear, apply the interpretation of PR018 Hydraulic pressure.
Clear the computer fault memory.
Carry out the programming procedure for the Hydraulic unit - gearbox kit (without clutch) or Clutch or
gearbox + Clutch (see Replacement of components).
If the fault is still present, this means there is an internal mechanical fault with the gearbox, contact Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

Check the adjustment of the brake light switch on the pedals.
Check for continuity with the pedal depressed, between connections AP10 (track 2) and 65A of component 160.
Replace the switch if necessary (see MR 411 Mechanical systems, 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 systems, 83D Cruise control, Brake light switch:

STATUS
DEFINITIONThese statuses indicate the position of the brake pedal.
NOTESUse the Wiring Diagrams Technical Note for New TWINGO.
Engine stopped, ignition on
–Brake pedal released: ET003: "Closed" and ET004: "Open".
–Brake pedal depressed: ET003: "Open" and ET004: ''Closed".

procedure.
Electrical check of the sensor
Check the condition of the 15 A fuse of the brake light switch located on component 1016.
Check the brake light switch is correctly positioned on the brake pedal.
Check the condition and correct connection of component 160.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check for the + after ignition feed on both connections AP10 of component 160.
If there is no + after ignition feed, check the continuity and insulation to earth of the two connections AP10
between components 160 and 1016.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, W iring: Precautions for repair), repair the wiring, otherwise replace it.
Pedal released:
Check the continuity between connections AP10 (track 4) and 5A of component 160.
