ALP1 No dialogue with the computer
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.

NOTESOnly refer to Customer complaints after carrying out a complete fault finding
procedure with the diagnostic tool and the conformity check.
Carry out a road test using the diagnostic tool, making sure that status ET013 Gear engaged operates normally.
If the customer complaint occurs with the brake pedal released, check that status ET004 Brake light switch
(Closed) is NO.
If not, adjust the brake light switch and the brake pedal.
Make sure that the instrument panel display of the gear engaged matches the gear lever position.
Check the automatic transmission wiring harness (sequence solenoid valve control).
Replace it if necessary.
Check that the gear lever cable is working properly and adjust it if necessary.
Check that the multifunction switch is working correctly.
If the fault is still present, replace the multifunction switch.
Carry out fault finding on the injection system.
Check engine speed signal PR006 during a road test at a steady speed.
If the signal is wrong, replace the engine speed sensor.
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

Switch off the ignition and disconnect the modular connector.
Switch on the ignition again and check for + 12 V after ignition feed on connection AP11 of component 485.
Switch off the ignition and check the continuity on the following connections, with the gear lever in position R:
●Connection code H66P between components 485 and 1337.
●Connection code AP11 between components 485 and 1337.
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 that the gear lever cable is correctly adjusted and check the instrument panel display.
If the continuity is faulty, replace the multifunction switch.
Switch on the ignition.
With the gear lever in position R, check for + 12 V after ignition feed on the following connections:
●Connection code H66P between components 172 and 1337.
●Connection code H66P between components 173 and 1337.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A,
