BRAKE LIGHT SWITCH (OPENING)
NOTESThere must be no present or stored faults.
The status displays OPEN with the pedal released and changes to CLOSED with the brake pedal depressed.
Check the cleanliness and the condition of the brake light switch connections.
Check the positioning, setting and correct operation of the brake light switch (Pay attention to the floor carpet which
can block the switch).
Disconnect the battery.
Disconnect the computer. Check the cleanliness and condition of the connections.
Use the Universal bornier Elé. 1681 to check the insulation, continuity and the absence of interference resistance
on the following connection:
●Connection code 5A, between components 119 and 160.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the correct status is not displayed, replace the switch.
AFTER REPAIRRepeat the conformity check from the start.

If the fault comes from converter locking, apply the interpretation of faults DF016 Solenoid valve circuit locking,
DF018 Lockup slippage and DF120 Controlled slipping.
If the fault comes from the engaged gear, carry out fault finding on the multifunction switch.
Check that statuses ET123, ET124 and ET125 operate correctly.
–ET123 "Multifunction switch S2".
–ET124 "Multifunction switch S3".
–ET125 "Multifunction switch S4".
Check the multifunction switch settings.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

TORQUE CONVERTER
NOTESThere must be no present or stored faults.
This indicates the status of the torque converter.
The status should be ACTIVE when the vehicle is driven with a gear engaged.
The status should be INACTIVE when starting, changing gears, or if the vehicle is stopped.
If the status does not function as specified, apply the interpretation of fault DF016 Converter lockup solenoid
valve circuit.
If the fault is still present, contact your Techline.
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.

GEAR LEVER UNLOCKING
NOTESThere must be no present or stored faults.
This status indicates whether or not the gear lever is unlocked.
Lever in position P.
The status is YES when the brake pedal is pressed.
The status is NO when the brake pedal is not pressed.
Lever in any position except P.
The status is YES whether or not the brake pedal is pressed.
Check that the instrument panel indicates that the lever is in position P.
Check that, when the brake pedal is pressed, the "Press brake pedal" message disappears from the instrument
panel.
Check the gear lever operation up to the multifunction switch.
Adjust the cable if necessary.
Check that statuses ET154, ET123, ET124 and ET125 Multifunction switch are correct.
If the correct status is not displayed, use the interpretation of fault DF095 Gear lever locking electromagnet
circuit.
If the fault is still present, contact the Techline.
