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,
–oil temperature ≤ - 40 ˚C,
–vehicle speed > 6 mph (10 km/h).
–in the event of short circuit-:
–+ after ignition feed,
–oil temperature > 180 ˚C,
–vehicle speed > 6 mph (10 km/h).
–accelerator pedal > 12.5 % and engine speed > 305 rpm.
(detection time in the event of short circuit- is 10 minutes).
Effect on system:
–in the event of open circuit or short circuit+:
Gear change quality is reduced.
lock-up is inhibited.
–in the event of short circuit-:
The transmission operates as if the temperature had increased.
Customer complaint:
–in the event of open circuit or short circuit+:
If the fault occurs while driving, the transmission engages fixed 5th gear.
Restarting is in 3rd gear.
Gear change quality is reduced.
Fault warning light on
–in the event of short circuit-:
Fault warning light on
Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Check that the coolant temperature (see 13B, Diesel injection, EDC16, CP33 M9R 721 Conformity check)
is ≥ - 40 ˚C (the transmission oil temperature sensor is within its operating range).
If the oil temperature ≤ - 40 ˚C, move on to step 1.
If the oil temperature is ≥ - 40 ˚C, deal with the fault; 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.

Step 1:
Start the vehicle, check that engine coolant temperature is ≥ 20 ˚C.
If the fault is stored, deal with the other faults displayed on the diagnostic tool. In the absence of faults, end of
fault finding.
If a fault is still present, deal with it, then move on to step 2.
Step 2:
Look for any damage to the harness and check the condition and connection of the automatic transmission
computer and automatic transmission 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.
Disconnect the connector from component 119, measure the resistance of the oil temperature sensor
(on the connector of component 119) between the following connections:
●Connection code 5BZ,
●Connection code 5BY.
The resistance should be between:
–4.208 ± 0.42 kΩΩ Ω Ω
at 20 ˚C,
–1.947 ± 0.19 kΩΩ Ω Ω
at 40 ˚C,
–0.988 ± 0.09 kΩΩ Ω Ω
at 60 ˚C,
Is the resistance correct?
If YES, contact the Techline.
If NO, move on to step 3.
Stage 3:
Disconnect connector R22 and check continuity and insulation on the following connections:
●Connection code 5BZ,
●Connection code 5BY.
Between components 119 and R22.
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 4.
If NO, replace the external wiring harness on the automatic transmission.
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.

Stage 4:
Measure the resistance of the oil temperature sensor (on connector R22) between the following connections:
●Connection code 5BZ,

at 60 ˚C,
Is the resistance correct?
If YES, and if the fault is still present, contact the Techline.
If NO, move on to step 5.
Stage 5:
Drain the automatic transmission (see, MR 370, Mechanical, 23A Automatic transmission, Oil change)
and remove the transmission housing (see, MR 370, Mechanical, 23A Automatic transmission, Hydraulic
distributor).
Measure the resistance of the transmission temperature sensor (on the connector of the internal wiring
harness on the transmission) between the following connections:
●Connection code 5BZ,
●Connection code 5BY.
The resistance should be between:
–4.208 ± 0.42 kΩΩ Ω Ω
at 20 ˚C,
–1.947 ± 0.19 kΩΩ Ω Ω
at 40 ˚C,
–0.988 ± 0.09 kΩΩ Ω Ω
at 60 ˚C,
Is the resistance correct?
If YES, move on to step 6.
If NO, replace the internal wiring harness on the automatic transmission.
Stage 6:
Measure the continuity and insulation of the following connections:
●Connection code 5BZ,
●Connection code 5BY.
Between components R22 and the internal connector in the transmission.
Are the continuity and insulation correct?
If YES, contact the Techline.
If NO, replace the wiring harness between connector R22 and the internal connector in the transmission.
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.

up/brake 1 solenoid valve circuit".
Conditions for applying fault finding procedures to stored faults:
The fault is declared present after:
If in lock-up:
