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 displays "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.

EXCHANGER FLOW CONTROL SOLENOID VALVE*
NOTESThere must be no present or stored faults.
The exchanger flow control solenoid valve command status displays "ACTIVE" in the following conditions:
–gearbox oil temperature is above 100˚C,
–engine speed is greater than 2000 rpm.
With other conditions, the solenoid valve status displays "INACTIVE".
Disconnect the computer. Check the cleanliness and condition of the connectors.
Check the continuity of the following connections:
●connection code 5DD, between components 119 and 1019,
●connection code 5DN, between components 119 and 1019.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Measure the resistance of component 1019 between the following connections:
●connection code 5DD,
●connection code 5DN.
The value should be 40 Ω ± 2 at approximately 23 ˚C.
If the connection or connections are 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 resistance is greater than 50 Ω, check the wiring harness, computer connector and modular connector.
If the status of the command fails to change, use the interpretation of fault DF017 "Exchanger flow solenoid valve
circuit".
AFTER REPAIRRepeat the conformity check from the start.

OIL PRESSURE
NOTESThere must be no present or stored faults.
Immobilise the vehicle: handbrake on and brake pedal depressed.
Check the oil pressure values on the diagnostic tool:
–engine not running: pressure reading less than 0.2 bar.
–engine at idle speed (~ 820 rpm) and gear lever at D or R: pressure reading ~ 2.6 bar.
–engine speed ~ 1400 rpm and gear lever at D or R: pressure reading ~ 8.7 bar.

GEARBOX OIL TEMPERATURE
NOTESThere must be no present or stored faults.
Gearbox oil temperature values vary according to how the vehicle is used.
Check the oil temperature values on the diagnostic tool:
Minimum temperature: - 40 ˚C.
Maximum temperature: + 140 ˚C.
These values relate to normal operation of the vehicle.
AFTER REPAIRRepeat the conformity check from the start.

TURBINE SPEED
NOTESThere must be no present or stored faults.
Turbine speed varies according to oil temperature and pressure.
Turbine speed depends on engine speed.
Check the turbine speed on the diagnostic tool:
Gear lever in position N.
Oil temperature 43 ˚C: engine speed ~ 762 rpmturbine speed ~ 681 rpm.
Oil temperature 45 ˚C: engine speed ~ 743 rpmturbine speed ~ 654 rpm.

GEARBOX OIL PRESSURE SENSOR VOLTAGE
NOTESNo faults should be present or stored.
ELECTRICAL CONFORMITY OF THE SENSOR:
Check for continuity and absence of interference resistance on the following connections:
●connection code 5U, between components 119 and 781,
●connection code 5W, between components 119 and 781,
●connection code 5V, between components 119 and 781.
If any of the connections are 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 all the connections are correct, check for + 5 V on connection 5U of component 781.
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 all the connections are correct, check for earth on connection 5V of component 781.
If any of the connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
