Check the following conformity:
CF192 Central door locking with LC093 Central door locking.
Check that fuses F14 (20 A) are sound and correctly fitted in the passenger compartment fuse and relay box
(for vehicles equipped with deadlocking function).
Replace the fuse if necessary.
Check the condition and connection of the PE1, PE2 and PE3 connectors of the UCH (tabs bent, broken,
oxidised etc.).
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 the condition and connection of the electric central door locking connectors for the driver's and passenger's
doors and the tailgate (tabs bent, oxidised, bent etc.).
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.
Lock component 1391 to check the status of the signal on the following connections using an oscilloscope
(refer to test 1 "Central door locking" (See 87B, Passenger compartment connection unit, test 1)).

Oscilloscope red test pin on
connection 20S of component 1322Oscilloscope black test pin on connection MHY of
component 1322
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

Carry out complete fault finding of the injection system (see 13B, Diesel injection and see also 17B, Petrol
injection) (See MR 411 Mechanical systems, 13A, Fuel supply) (see MR 411 Mechanical systems, 13C,
Preheating) (See MR 411 Mechanical systems, Ignition).
If the fault is still present, contact Techline.
Check that there are no powerful electromagnetic wave sources (CB (Citizen Band), mobile phone in close
proximity to the transponder ring).
Switch the ignition off and then on again.
Check that fuse F8 (15 A) is sound and fitted in the passenger compartment fuse and relay box.
Replace the fuse if necessary.
Check the condition and connection of the transponder ring 4-track connector (bent, oxidised, broken tabs).
Repair if necessary.
Check that the earth on connection NAM of the transponder aerial connector is perfect.
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 AP43 of the transponder aerial connector.
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 the condition and connection of the 40-track UCH connector PE1 (tabs bent, broken, oxidised, etc.).
Repair if necessary.
Check the insulation, continuity and absence of interference resistance of the following connections:
●Connection code 80Y between components 1618 and 645.
●Connection code 80X between components 1618 and 645.
●Connection code AP43 between components 1618 and 1016.
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 connections are correct but the fault is still present, replace the transponder ring.
AFTER REPAIRCarry out another fault finding check on the system.
