STOREDINVALID RAW ENGINE TORQUE MULTIPLEX SIGNAL
1.DEF: Multiplex frames absent or values invalid (fault with the computer generating
the signal or multiplex line connection fault)
NOTESSystem effects:
The line pressure is not being checked properly.
Customer complaint:
Fault warning light comes on.
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting occurs in fixed 3rd gear (no more gear changes).
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Run a multiplex network test (see 88B, Multiplex).
Carry out a test on the engine management computer (see 13B, Diesel injection, Conformity check)
(EDC16 CP33 M9R 721).
Check the continuity and insulation against earth of the following connections:
●Connection code 3MS.
●Connection code 3MT.
Between components 119 and 120.
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 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

NOTESCustomer complaint:
Switch to safe mode:
–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.

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, switch to R if engine speed is lower than 2000 rpm.
Fault warning light comes on.
Note:
If at least one solenoid valve is faulty, replace the hydraulic distributor.
Look for any damage to the wiring and check the condition and connection of the connectors for components 119
and 754.
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.
AFTER REPAIRDeal with any other faults. Clear the fault memory.

–in the event of short circuit+:
No effect.
–in the event of open circuit or short circuit-:
If the fault occurs on gears 1 to 4, in D mode, the transmission switches to Neutral
(see DF256 Erratic gear jumps). Then system switches to fixed 5th gear mode after
the vehicle has stopped.
Customer complaint:
–in the event of short circuit+:
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting in fixed 5th gear (no more gear changes).
Significant jolting during gear changes.

–in the event of open circuit or short circuit-:
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting in fixed 5th gear (gear change impossible)
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 automatic
transmission computer and hydraulic distributor connectors.
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 5LW of component 754.
Is the + after ignition feed still present?
If YES, move on to step 1.
If NO, move on to step 8.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
