SEQUENCE SOLENOID VALVE 5 CONTROL
NOTESThere must be no present or stored faults.
This status displays ACTIVE when the gear engaged is 1 and INACTIVE when other gears are engaged.
Disconnect the computer. Check the cleanliness and condition of the connectors.
Check the continuity of the following connections:
●Connection code 5DL between components 119 and 754.
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.
Measure the resistance of component 754 between the following connections:
●Connection code 5AU.
●Connection code 5DL.
The value should be 40 ΩΩ Ω Ω
± 2 ΩΩ Ω Ω
at approximately 20˚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.
Reconnect the computer.
Activate the solenoid valves with command AC024 Actuator sequential control and measure the current in the
solenoid valves.
If the current is 250 mA, the solenoid valve is working properly.
If the current is weaker, check the computer connections and harness up to the solenoid valve.
If the status is still not correct, use the interpretation of fault DF088 EVS5 Sequence solenoid valve circuit.
If the fault is still present, replace the electric/hydraulic interface.
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.
