Renault Clio: Sequential gearbox: Precautions for the repair
D4F or K9K, and JA3 or JA5

I - SEQUENTIAL GEARBOX
WARNING
If any operation is carried out on the electro-hydraulic
unit, it is essential to clean the unit using a cleaning
product and compressed air.
Never leave the circuit open and never use a high
pressure cleaner.
II - SEQUENTIAL GEARBOX COMPUTER
To disconnect the computer, switch off the ignition and
wait for 1 minute.
III - ELECTRO-HYDRAULIC UNIT
Discharge the pressure accumulator using the Diagnostic
tool before any operation on the electro-hydraulic
unit.
Pressure accumulator: Removal - Refitting
K9K, and JA5

REMOVAL
I - REMOVAL PREPARATION OPERATION
IMPORTANT
Before any operation on the sequential system,
discharge the accumulator using the Diagnostic
tool.
- To discharge the accumulator, run command
" Discharge pressure accumulator " AC081.
To confirm the pressure drop, read the " Hydraulic
pressure " parameter for the resulting value.
If there is still pressure in the accumulator, re-run the
" Discharge pressure accumulator " command until
the pressure is negligible and will not pose a risk
when the high pressure pipes are removed.
The pressure reading must be close to zero.
- Remove:
- the battery (see Battery: Removal - Refitting)
(MR 392, 80A, Battery),
- the battery tray (see Battery tray: Removal - Refitting)
(MR 392, 80A, Battery),
- the air filter unit (see Air filter unit: Removal - Refitting)
(MR 392, 12A, Fuel mixture).

- Remove:
- the lifting eye nut on the gearbox (1),
- the lifting eye on the gearbox (2).
II - OPERATION FOR REMOVAL OF PART
CONCERNED

- Remove the pressure accumulator (3) using the
(Mot. 445).
REFITTING
I - REFITTING OPERATION FOR PART
CONCERNED
- Fit the pressure accumulator.
- Tighten the pressure accumulator using the (Mot.445).
- Affix the safety label to the pressure accumulator.
- Refit:
- the lifting eye on the gearbox,
- the lifting eye nut on the gearbox.
- Tighten to torque the lifting eye nut on the gearbox
(21 Nm).
- Refit:
- the air filter unit (see Air filter unit: Removal - Refitting)
(MR 392, 12A, Fuel mixture).
- the battery tray (see Battery tray: Removal - Refitting)
(MR 392, 80A, Battery),
- the battery (see Battery: Removal - Refitting)
(MR 392, 80A, Battery),
II - FINAL OPERATION.
- Carry out the necessary programming (see Fault
finding - Replacement of components) (MR 394,
21B, Sequential gearbox).
WARNING
After the accumulator has been fully filled (15
seconds after the ignition has been switched on):
the oil is at the MIN mark.

This system supplements the ABS
and helps reduce vehicle stopping distances.
Operating principle
The system is for detecting an emergency
braking situation. In this case,
the braking assistance immediately develops
maximum power and may trigger
ABS regulation.
