STOREDVEHICLE 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 a test.
The vehicle speed transmitted by the multiplex line > 12 mph (20 km/h) and the speed
of transmission output sensor < 3 mph (5km/h) then the vehicle speed transmitted by
multiplex line < 12 mph (20km/h).
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 and check the condition and connection of the connectors for components 119
and 1060.
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.
If + after ignition feed is present, move on to step 1.
If + after ignition feed is not present, move on to step 2.
Step 1:
Check the continuity and insulation of the following connections:
●Connection code 5TA.
●Connection code 5T.
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 1140.
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.

1.DEF: Hydraulic, mechanical or electrical fault on solenoid valves, deal with the
other faults first
NOTESConditions for applying fault finding procedures to stored faults:
The fault appears after:
1st case: when driving, in Drive or in Manual
ratio > ratio setpoint,
and output speed ≥ 300 rpm,
and turbine speed ≥ 300 rpm,
and engine speed ≥ turbine speed - 50 rpm,
and (if 1st with engine braking, accelerator pedal ≥ 6.25 % OR,
if 1st, accelerator pedal ≥ 30.75 % OR,
if 2nd to 6th accelerator pedal ≥ 6.25 %).
2nd case: while driving, reverse gear
ratio > ratio setpoint,
and output speed ≥ 300 rpm,
and turbine speed ≥ 300 rpm,
and engine speed ≥ turbine speed - 50 rpm,
and accelerator pedal ≥ 6.25 %.
3rd case: stationary, in Drive or in Manual
Difference between engine speed and mapping > threshold,
and engine speed increases constantly for 250 ms.
4th case: stationary, reverse gear
Difference between engine speed and mapping > 0,
and engine speed increases constantly for 250 ms.
System effects:
No engine torque transmitted to wheels.
Switch to defect mode occurs during vehicle speed safety conditions (vehicle speed
< 32 mph (54 km/h)).
The system effects will vary depending on which solenoid valve is faulty:
–If caused by brake 2 solenoid valve, system switches to fixed 2nd, 3rd or 5th gear
safe mode.
–If caused by clutch 2 solenoid valve, system switches to fixed 2nd, 3rd or 6th gear
safe mode.
–If caused by the clutch 3 solenoid valve, system switches to fixed 2nd, 3rd, 4th or 5th
gear safe mode.
–If caused by clutch 1 solenoid valve, system switches to fixed 3rd, 5th or 6th gear
safe mode.
In all cases, restarting is in 3rd gear.
If vehicle stopped in Drive, system switches to fixed 5th gear if engine speed is lower
than 2000 rpm.
If vehicle stopped in "R" mode, switching to "R" mode is done if engine speed is less
than 2000 rpm.
In reverse, moving off when "kick-down" detected.
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.
