* EV: Solenoid valve.ET020
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.

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.

CURRENT TURBINE SPEED
NOTESThere must be no present or stored faults.
Check the cleanliness and condition of the turbine speed sensor and its connections.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V and the
following connections:
●connection code 5DA, between components 119 and 1017,
●connection code 5DB, between components 119 and 1017.
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.
Check the turbine speed on the diagnostic tool:
Gear lever position at N or P.

DIFFERENCE BETWEEN REFERENCE PRESSURE AND OIL
PRESSURE
NOTESThere must be no present or stored faults.
The reference pressure values are stored in the transmission computer memory and depend on how the vehicle
is used.
The oil pressure is regulated according to the reference pressure. The oil pressure values must always be close
to the reference pressure.
This parameter is the difference between parameter PR138 Reference pressure and parameter PR003 Oil
pressure.
–engine not running: reference pressure reading 21 bar.
oil pressure reading = 0 bar.
–engine at idle speed (~ 700 rpm) and selector lever at D or R: reference pressure reading ~ 2.7 bar.
oil pressure reading = ~ 2.6 bar.
–engine speed ~ 1400 rpm and selector lever at D or R: reference pressure reading ~ 8.9 bar.
oil pressure reading = ~ 8.7 bar.
AFTER REPAIRRepeat the conformity check from the start.
