Fault finding - Role of components
Role of main automatic transmission components
Automatic transmission computer:
The gearbox computer is used to manage the entire system.
Its role is to define the optimum operating mode for the automatic transmission (modify the torque transmitted to the
drive wheels by the automatic transmission), inform the driver (instrument panel, information display, buzzer) and
communicate with the other computers.
To carry out this function, the transmission computer takes account of:
–the operation of the gearbox,
–signals exchanged with other computers,
–driver requests.
Transmission oil temperature sensor:
Its role is to inform the automatic transmission computer of the transmission oil temperature.
Transmission input speed sensor:
Its role is to inform the automatic transmission computer of the turbine speed.
Transmission output speed sensor:
Its role is to inform the automatic transmission computer of the vehicle speed.
Brake light switch:
Its role is to inform the automatic transmission computer that the driver has depressed the brake pedal.
Multifunction switch:
Its role is to inform the automatic transmission computer of the gear lever position.
Shift-lock:
The role of this function is to lock the lever in position "P" and to immobilise the vehicle when stationary.
Solenoid valves:
The solenoid valves are fitted in the factory and cannot be removed from the hydraulic distributor to ensure optimum
gearbox operation, therefore they cannot be replaced separately.
The automatic transmission has two types of solenoid valve:
–2 "all or nothing" solenoid valves,
–6 "progressive" solenoid valves.
Of these 8 solenoid valves, 7 are used to control gear changes in automatic and manual modes, and one solenoid
valve controls the oil pressure in the automatic transmission hydraulic distributor.
Instrument panel display:
The purpose of this function is to manage the transmission of multiplex line signals required for the instrument panel
display.
On the instrument panel:
–a fault warning light,
–a message on the instrument panel in case of irregularity,
–an information display: gear lever position/gear engaged/brake pedal depressed indicator light/lever position in P
or N request indicator light.
On the gear lever:
–Position: P / R / N / D / M+/-,
–Shift-lock: lever lock.

"SHIFT LOCK" FUNCTION:
Purpose of this function:
Shift-lock: locking the gear lever in position "P" and blocking the transmission to immobilise the vehicle while
stationary.
To release the gear lever from position "P", the vehicle must be stationary and the brake pedal depressed.

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.

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.
