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.
