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.

Check sensor operation:
Establish consistency between the position of contacts under the CLIP (ET012 "Gear lever position") and the
position displayed on the instrument panel.
Check the condition and setting of the control (see MR 370 Mechanical, 37A, Automatic gear controls,
Adjustment) and the mountings connecting the lever to the transmission.
If the fault remains stored, do not replace the sensor.
Look for any damage to the wiring harness, and check the condition and connection of the transmission
computer and multifunction switch connectors.
If there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Check for + after ignition feed on connection AP4 of component 779.
Is the + after ignition feed still present?
If YES, move on to step 1.
If NO, move on to step 3.
Step 1:
Disconnect the connector from component 119, check the insulation and continuity of the following connections
(on the connector of component 119):
Position of gear lever = P:
●Connection code 5DF.
●Connection code AP4
Position of gear lever = R:
●Connection code 5DG.
●Connection code AP4.
Position of gear lever = N:
●Connection code 5DH.
●Connection code AP4.
Position of gear lever = N:
●Connection code 5DJ.
●Connection code AP4.
If any of the 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 continuity and insulation are correct, contact the Techline.
Are the continuity and insulation correct?
If YES, and if the fault is still present, contact the Techline.
If NO, check the intermediate connector R22 and move on to step 2.
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.
