5. FAULT FINDING LOG
You will always be asked for this log:
–when requesting technical assistance from Techline,
–for approval requests when replacing parts for which approval is mandatory,
–to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY ADVICE
Safety rules must be observed during any work on a component to prevent any damage or injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–use the appropriate tools,
–Immobilise the vehicle for all tests in the workshop on the automatic transmission with the engine running. IMPORTANTIMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG
EACH TIME FAULT FINDING IS CARRIED OUT.

CO.0 : Open circuit or short circuit to earth
NOTESConditions for applying the fault finding procedure to stored faults:
The fault appears after a timed period of 10 seconds with the engine running
at 2000 rpm.
Special notes:
Use bornier Elé. 1681 for all operations on the computer connectors.
Disconnect the battery.
Disconnect the modular connector, and check the cleanliness and condition of the connections.
Disconnect the computer. Check the cleanliness and condition of the connections.
Check the insulation, continuity and the absence of interference resistance to earth, to + 12 V of the following
connection:
●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 the connection(s) are faulty and if there is a repair method (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Reconnect the modular connector.
Measure the resistance of component 781 between connections 5V and 5W on the computer connector
(female connector).
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.
Replace the sensor if the resistance is not approximately 20 kΩΩ Ω Ω
.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the
diagnostic tool.

Carry out a conformity check to detect any possible faults.
Check the setting point of the converter (see MR 364 Mechanical, 23A, Automatic transmission, Checking the
setting point of the converter (for Mégane II and Scénic II)
If the setting point value is not correct, carry out the following checks:
–Check the oil pressure using PR003 Oil pressure:
–Warm engine with gearbox oil temperature between 65 and 90˚C.
–Take the line pressure reading under the following 3 conditions:
Important
The vehicle must be stationary: handbrake on and brake pedal depressed, no accessories operating
(e.g.: air conditioning)
1Engine speed idling:
Shift the gear lever to R, N and D, the pressure reading must be greater than 2.5 bar.
2Engine speed at 1200 rpm:
–gear lever in R position, the pressure reading must be greater than 4 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 5.5 bars.
3Engine speed at 2200 rpm:
–gear lever in R position, the pressure reading must be greater than 11 bars.
–gear lever in D position, the pressure reading in first gear must be greater than 11 bars.
If the line pressure value read under one of these 3 conditions is incorrect, replace the line pressure sensor.
If the line pressures recorded under these 3 conditions are good, then the pressure sensor is operating correctly.
Replace the pressure regulating solenoid valve.
If the fault is still present after the pressure regulating solenoid valve has been replaced, replace the hydraulic
distributor and during refitting, take into account Technical Note 4194A Automatic transmission indicator strip
flashing for the adjustment of the ball detent blade.
If the fault is still present, contact the Techline
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present when the engine is running and the gear lever is at P.
Disconnect the battery.
Disconnect the modular connector, and check the cleanness and condition of the connections.
Disconnect the computer. Check the cleanliness and condition of the connections.
Use the universal bornier Elé. 1681. Check the continuity and insulation of the following connections:
●Connection code 5DA, between components 119 and 1017.
●Connection code 5DB, between components 119 and 1017.
If the connection(s) are faulty and if there is a repair method (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Reconnect the modular connector.
Measure the resistance of component 1017 between the following connections:
●Connection code 5DA.
●Connection code 5DB.
If the connection(s) are faulty and if there is a repair method (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
The turbine speed sensor resistance is 300 ΩΩ Ω Ω
± 40 ΩΩ Ω Ω
at a temperature of approximately 20˚C.
If the value is not correct, replace the turbine speed sensor.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the
diagnostic tool.
