STOREDTURBINE SPEED SENSOR CIRCUIT
1.DEF: Open circuit or short circuit
NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–+ after ignition feed,
–with the engine running,
–vehicle speed > 24 mph (40 km/h),
–engine speed > 1500 rpm,
–turbine speed < 600 rpm and accelerator pedal > 0 %.
Effect on system:
Impossible to calculate gear.
Customer complaint:
Gear on which fault occurred is fixed. Restarting in fixed 3rd gear (no more gear
changes). Manual mode is inhibited. Fault warning light comes on.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Look for any damage to the wiring harness, and check the condition and connection of the transmission
computer and the turbine speed sensor.
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.
Check for + after ignition feed on connection AP4 of component 1060.
Is the + after ignition feed still present?
If YES, move on to step 1.
If NO, move on to step 2.
Step 1:
Check the continuity and insulation of the following connections:
●Connection code 5HN.
●Connection code 5DA.
Between components 119 and 1060.
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.
Check the intermediate connector R22, if the fault is still present, replace component 1060.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.

LEVER POSITION SWITCH CIRCUIT
1.DEF: Open circuit or short circuit
NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–in the event of open circuit or short circuit-:
–+ after ignition feed and change of lever position.
–in the event of short circuit+:
–+ after ignition feed, initial lever position: Position "P", "R", "N" or "D".
Effect on system:
The lever value is held at its previous valid position until the fault is confirmed. Then
the lever position becomes DRIVE (internal software variable) irrespective of the fault.
–If the fault is present and the lever in position "P", the transmission is in "N", hydraulic
neutral.
–If the fault is present and the lever in position "R", the transmission is in "R", hydraulic
reverse.
–If the fault is present and the lever in position "N", the transmission is in "N", hydraulic
neutral.
–If the fault is present and the lever in position "D", the transmission is in "D", hydraulic
forward gear.
lock-up is inhibited.
Customer complaint:
No lever position display on the instrument panel following fault confirmation and
starting impossible.
If the engine is already running when the fault occurs, there is jolting when shifting from
"P" or "N" to "R" or "D".
Fault warning light comes on.
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Note:
It is possible to produce this fault if the driver or operator voluntarily keep the lever between two normal positions
for longer than 2 seconds.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
