OIL TOO HOT SIGNAL
NOTESThere must be no present or stored faults.
This status means the oil temperature is above the normal operation temperature.
The status displays NO if the gearbox oil temperature is below 140˚C.
The status changes to YES when the gearbox oil temperature rises above 140˚C.
If the correct status is not displayed, use the interpretation of fault DF177 Automatic transmission overheating.
AFTER REPAIRRepeat the conformity check from the start.

* EV: Solenoid valve.ET020
EXCHANGER FLOW CONTROL SOLENOID VALVE*
NOTESThere must be no present or stored faults.
The exchanger flow control solenoid valve is ACTIVE when the gearbox oil temperature exceeds 100˚C
and the engine speed exceeds 2000 rpm.
Otherwise the solenoid valve remains inactive.
Run command AC024 Actuator sequential control and check that the activation status changes from INACTIVE
to ACTIVE.
When powered, if the solenoid valve is ACTIVE the voltage should be 0 V.
When powered, if the solenoid valve is INACTIVE the voltage should be 12 V.
Reconnect the computer.
Activate the solenoid valves with command AC024 Actuator sequential control and check the solenoid valve
current.
If the current is 260 mA, the solenoid valve is working properly.
If the current is weaker, check the computer connections and harness up to the exchanger flow solenoid valve.
If the status of the command fails to change, use the interpretation of fault DF017 Exchanger flow solenoid valve
circuit.
If the fault is still present after the fault finding procedure for fault DF017 Exchanger flow solenoid valve circuit
has been followed, contact your Techline.
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.

wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the value is not correct, the solenoid valve or the electric/hydraulic interface harness is damaged.
Check gearbox oil grade and level.
If an operation is necessary (see MR 364 Mechanical, 23A, Automatic transmission, Filling-Levels
(for Mégane II) and MR 370 Mechanical, 23A, Automatic transmission, Draining-Filling (for Scénic II)).
Check that the gearbox is not leaking oil.

See the Taking line pressure section of the Workshop Repair Manual.
Set up the pressure gauge for a line pressure reading.
With a warm engine and the gearbox oil temperature between 60 and 80 ˚C, check the difference between the line
pressure sensor (PR003) and the pressure gauge under the following conditions:
–with the engine stopped, the pressure gauge should indicate a residual pressure of about 0.2 bar.
If the sensor reading differs by more than 0.2 bar, replace the sensor.
–with the engine running at about 1200 rpm the pressure gauge reading should reach 7 bar.
If the sensor reading differs by more than 0.8 bar, replace the sensor.
Warm engine with gearbox oil temperature between 60 and 80 ˚C.
Take the line pressure readings under the following conditions:
–with the gear lever in P or N and engine speed at 2000 rpm the pressure should be between 2.6 and 3.2 bar.
–with the gear lever at R and engine speed at 2000 rpm, the pressure should be above 4 bar.
–with the gear lever at D and engine speed at 2000 rpm, the pressure in first gear should be greater than 7 bar.
If the values are not correct, there is a fault inside the gearbox.
