NOTESCheck the 20A permanent computer feed fuse marked 15 in the Protection and
Switching Unit. Check the cleanliness and condition of the connections.
Check the 5A after-ignition computer feed fuse marked 5H in the Protection and
Switching Unit.
Replace the fuses if necessary.
Check the cleanliness and condition of the connections.
Engine speed zero and gear lever in position P or N.
If the solenoid valves are not activated, check:
–the gearbox oil level,
–the cleanness and condition of the computer connector and modular connector,
Check the insulation, continuity and absence of interference resistance on the following connections:
●Connection code 5AU between components 119 and 754.
●Connection code 5AV between components 119 and 754.
●Connection code 5AW between components 119 and 754.
●Connection code 5AX between components 119 and 754.
●Connection code 5AY between components 119 and 754.
●Connection code 5DL between components 119 and 754.
●Connection code 5DM between components 119 and 754.
●Connection code 5BA between components 119 and 754.
●Connection code 5AZ, between components 119 and 754.
●Connection code 5DD between components 119 and 1019.
●Connection code 5DN between components 119 and 1019.
If the fault is still present, contact the Techline.
AFTER REPAIRRepeat the conformity check from the start.

NOTESNone.
Try the diagnostic tool on another vehicle.
Check:
–the connection between the diagnostic tool and the diagnostic socket (connection and cable in good condition),
–the power supply to the computer,
–the engine and passenger compartment fuses.
Check that the CLIP sensor is supplied by connections BP32, MAN and NAM of component 225, displayed when
both red indicator lights on the sensor illuminate.
Make sure that the CLIP sensor is connected to the computer's USB port.
Make sure the CLIP sensor is communicating properly with the vehicle's computers; this can be seen by the two
green diodes on the sensor lighting up.
Check the following connections on component 225:
●Connection code AP43 (+ after ignition feed).
●Connection code BP32 (+ battery).
●Connection code MAN (earth).
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.
No communication on line K
Check the continuity, insulation and absence of interference resistance on line K of the diagnostic socket.
Disconnect the automatic transmission computer connector to check the insulation, continuity and the absence
of interference resistance of the following connections:
●Connection code AP4 between components 119 and 1337.
●Connection code BP42 between components 119 and 1337.
●Connection code N between components 119 and 107.
●Connection code 3HK between components 119 and 225.
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 REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
