Renault Clio: Electro-hydraulic unit: Removal - Refitting

K9K, and JA5

REMOVAL

I - REMOVAL PREPARATION OPERATION

Note: When replacing the electric pump assembly, always replace the control relay.

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.

• Position the vehicle on a two-post lift (see Vehicle: Towing and lifting) (MR 392, 02A, Lifting equipment).

K9K, and JA5

Note: The electro-hydraulic unit includes the pump assembly and the actuator module.

• Remove:
  • the pump assembly (see 21B, Sequential gearbox, Pump assembly: Removal - Refitting, 21B-12),
  • the actuator module (see 21B, Sequential gearbox, Actuator module: Removal - Refitting, 21B-34).

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove the electro-hydraulic unit.

REFITTING

I - REFITTING OPERATION FOR PART CONCERNED

• Refit:
  • the actuator module (see 21B, Sequential gearbox, Actuator module: Removal - Refitting, 21B-34),
  • the pump assembly (see 21B, Sequential gearbox, Pump assembly: Removal - Refitting, 21B-12).

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.

D4F, and JA3
