Diagnostic

4.FAILURE: MISSING SIGNAL ON THE CODED LINE E.C.U. DECODER-
COMPUTER INJECTION

RECOMMENDATION

Check the continuity and the isolation related to the mass and + 12 V of the wiring between
the E.C.U. decoder PinA6 pin58 injection computer.
Fix it if necessary.

Set the contact on and perform the detection test using the CLIP tester at pin A 6 of the ECU
decoder.
Are there any impulses?

YES

Replace the ECU injection.

Replace the E.C.U. decoder.

Remove the memorised failures by means of the CLIP tester.

AFTER REPAIRING

Perform a conformity test.
Check the operation of the anti starting system.

5. FAILURE : DEFECTIVE COMMUNICATION ANTI STARTING SYSTEM -
E.C.U. DECODER

RECOMMENDATION

Check the continuity and the isolation related to the mass and + 12 V voltage of the wiring
between the anti starting system pin 4 pin A2 E.C.U. decoder
Fix it if necessary.

Check the anti starting bushing supply : + 12V to the pin 3 and the mass to pin 2.

Disconnect the E.C.U. decoder and measure the presence of +12 V at the pin A2 of the
decoder, the contact being taken off. If there it isn’t +12 V, check the fuse condition F03 from
the cockpit fuse box.
If the problem persists, replace the anti starting bushing.

Set the contact on and perform the impulse detection test at the pin A2 of the E.C.U. decoder.
Is there an impulse ?

YES

Replace the anti starting bushing

Replace the E.C.U. decoder

Remove the memorised failures by means of the CLIP tester.

AFTER REPAIRING

Perform a conformity checking.
Check the operation of the anti starting system.

6. STATE 11G: ACTIVATE THE RF REMOTE CONTROL/ RECEIVED RF SIGNAL
INDICATION

If the 17D state is PASSIVE, do not apply the next diagnostic
because the E.C.U. decoder is unused (new).

RECOMMENDATION Perform first the remote control synchronisation.

Do not access the next diagnostic if the state 11G remains
PASSIVE when activating the RF remote control at the blocking
and unlocking of the doors.

Check the blocking and unlocking of the doors using the second RF remote control. If this
is one is operating, then the battery of the first RF remote control must be replaced.

Check the presence of +12 V(+DC) at the pin1 of the anti starting bushing.
Is there +12V ?

Perform using the CLIP tester, the impulse detection test at the pin 1 of the anti
starting bushing, when using the RF remote control.
Are any impulses when using the remote control ?

YES

Replace the E.C.U. decoder.

Replace the anti starting bushing.

YES

Check the isolation related to the mass of the electric wiring between:
E.C.U. decoder

Pin B1             pole 1    anti starting bushing
Pin B2             pole 1     door locking switch
Pin B5        pole 5

Isolation against mass is good?
YES

Fix the electric wiring.

Replace the E.C.U. decoder

AFTER REPAIRING

Perform a conformity checking.
Check the operation of the anti starting system.

7. 11D STATE: OPERATE THE RF REMOTE CONTROL / GOOD RF SIGNAL
INDICATION

Do not access the following diagnostic unless the state 11D

RECOMMENDATION

becomes ACTIVE when operating the RF remote control.
Check if the keys belong to the vehicle in question.

There is a desynchronising between the code of the RF remote control and the E.C.U. decoder
if at the activation of the remote control, the 111D state remains PASSIVE and the state 11G
becomes ACTIVE for 3 seconds, then becomes PASSIVE. The blocking / unlocking of the
doors is not possible in this case.
Apply the corresponding procedure of resynchronisation (for one or 2 keys).

AFTER REPAIRING

Perform a conformity checking.
Check the operation of the anti starting system.
