LOWER SEQUENTIAL LEVER SWITCH
NOTESThere must be no present or stored faults.
This indicates the status of the lower sequential lever switch.
This status displays "ACTIVE" with the gear lever in position "M-".
This status displays "INACTIVE" with the gear lever in a position other than "M-".
Check the sequential lever supply on the following connections:
●check for + 12 V on connection AP43 of component 129,
●check for the vehicle earth on connection N of component 129.
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.
With the gear lever in position "M", measure the voltage of the following connections:
●check for the vehicle earth on connection 5H of component 129,
●check for the vehicle earth on connection 5FM of component 129.
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 any of the measured values is + 12 V, replace the sequential lever.
If the values are 0 V, check that the gear lever positions match the instrument panel display.
If the correct status is not displayed, use the interpretation of fault DF093 "Manual sequential controls circuits".
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.

UPPER SEQUENTIAL LEVER SWITCH
NOTESThere must be no present or stored faults.
This indicates the status of the lower sequential lever switch.
This status displays "ACTIVE" with the gear lever in position "M+".
This status displays "INACTIVE" with the gear lever in a position other than "M+".
Check the sequential lever supply on the following connections:
●check for + 12 V on connection AP43 of component 129,
●check for the vehicle earth on connection N of component 129.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

If any of the measured values is + 12 V, replace the sequential lever.
If the values are 0 V, check that the gear lever positions match the instrument panel display.
If the correct status is not displayed, use the interpretation of fault DF093 Manual sequential controls circuits.
AFTER REPAIRRepeat the conformity check from the start.

GEAR LEVER UNLOCKING
NOTESThere must be no present or stored faults.
This status displays "ACTIVE" when the gear lever is locked and "INACTIVE" when the gear lever is unlocked.
Check the status with:
–Gear lever in position "P".
–Instrument panel displaying "P" for the gear lever position.
Depress the brake pedal; the message on the instrument panel: Depress the brake pedal disappears.
The status displays "INACTIVE" with the brake pedal depressed and gear lever unlocking permitted.
The status displays "ACTIVE" with the brake pedal released and the gear lever locked in position "P".
This status can only be checked with the gear lever in position "P".
If the correct status is not displayed, use the interpretation of fault DF095 "Selector lever lock electromagnet
circuit".
AFTER REPAIRRepeat the conformity check from the start.
Make sure that shifting up and down through each gear works properly.

COOLANT TEMPERATURE
NOTESSpecial notes:
Only apply the checks if the parameter is inconsistent.
Run a multiplex network test (see 88B, Multiplex).
If parameter PR001 Coolant temperature is absent, refer to the interpretation of the parameter (see MR 366
Megane, 17B, Petrol injection or 13B, Diesel injection).
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.
AFTER REPAIRRepeat the conformity check from the start.

GEARBOX OIL TEMPERATURE
NOTESThere must be no present or stored faults.
Gearbox oil temperature values vary according to how the vehicle is used.
