NOTESConditions for applying fault finding procedures to stored faults:
The fault appears after:
Lever in "Drive" position, Gear engaged = 2, 6,
and accelerator pedal > 0 %, vehicle speed > 6 mph (10 km/h),
and for each gear, the status of brake 2 pressure switch does not correspond to the
solenoid control status.
(consult the interpretation of faults ET260 "Brake 2" in the fault finding chapter,
Interpretation of statuses).
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 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.
Manipulate the wiring harness in order to observe any change in the fault status (Present → stored).
Check the continuity and insulation of the following external wiring harness connections on the transmission:
●Connection code 5LK.
●Connection code 5LW.
Between components 119 and 754.
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.
Are the continuity and insulation correct?
If YES, move on to step 1.
If NO, replace the external wiring harness.
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.

–in the event of short circuit+:
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting in fixed 3rd gear (no more gear changes).
Risk of engine stalling.
Jolting during gear changes.
Fault warning light comes on.
–in the event of open circuit or short circuit-:
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting in fixed 3rd gear (no more gear changes).

Is the + after ignition feed still present?
If YES, move on to step 1.
If NO, move on to step 8.
Step 1:
Disconnect the connector from component 119, measure the resistance of the lock-up/brake 1 solenoid valve
(on the connector of component 119) between the following connections:
●Connection code 5BF.
●Connection code 5LW.
The resistance must be 5.3 ΩΩ Ω Ω
± 0.5 ΩΩ Ω Ω
at 20 ˚C.
Is the resistance correct?
If YES, contact the Techline.
If NO, move on to step 2.
Step 2:
Disconnect connector R22 and check continuity and insulation of the following connections:
●Connection code 5BF.
●Connection code 5LW.
