5. FAILURE : DEFECTIVE COMUNICATION ANTI STARTING SYSTEM - E.C.U.
DECODER
RECOMMENDATION -
Check the continuity and the isolation
related to the ground 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 ground to pin2.
Di sconnect the E.C.U. decoder and measure the presence of +12 V to the pin A2 of the
decoder, the contact being taken off. If there it isn’t +12 V, check the fuse state F15 (vehicles
up to 01.06.2001) or F07 fuse (vehicles after 01.06.2001).
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
NO Replace the anti starting bushing.
Replace the E .C.U. decoder.
Remove the memorised failure by means of the CLIP tester.
AFTER REPAIRING Perform a conformity checking.

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 should be replaced.
Check the presence of +12 V(+DC) at the pin1 of the anti starting bushing.
Is there +12V ?
Perform using CLIP tester, the impulse detection test a t 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.
NO Replace the anti starting bushing.YES
Check the isolation related to the ground of the electric wiring between:
E.C.U. decoder Pin B1 pole 1 anti starting bushing Pin B2 pole door locking switch
Pin B5 pole 3
Is the isolation related to the ground good?
YES Fix the electric wiring.
NO Replace the E .C.U. decoder.NO
AFTER REPAIRING Perform a conformity checking.

Check the continuity and the isolation related to the +12 V and to the ground of the electric
wiring on the line
E.C.U. decoder Pin B2 pole 1 door locking switch. Pin B5 pole 3
Fix the electric wiring if necessary or replace the switch.

A LP1. MISSING COMMUNICATION CLIP TESTER / E.C.U DECODER
RECOMMENDATION Check if the lines K and L are not perturbed by another computer
of the vehicle.
Check the situation of the F15 fuse ( up to 01.06.2001) or F7 (after 01.06.2001)
Replace it if necessary.
Be sure the CLIP t ester is not the cause of t he failure, by trying the communication with
another computer of the vehicle.
Check the tension of the battery (U>10,5V). If it is necessary, charge the battery.
Check the correct c onnection of the E.C.U. decoder to the wiring.
Check the supply of the E.C.U. decoder : - ground at pin A8 - supply (+IC) at pin A9
Be sure that the diagnostic socket is correctly supplied.
Check the continuity and the isolation of the electric wiring on the pins’ line corresponding to:
E.C.U. decoder A3 7 diagnostic socket
A4 15
If the dialogue CLIP tester – E.C.U. decoder cannot be established, then replace the decoder.
When the communication with the tester is established, solve
AFTER REPAIRING the failures displayed by CLIP.
Perform a conformity checking.

Analyse this failure and replace.
Fix the wiring.
Perform the following tests in order to find the
failure element:
- if the anti starting indicator is permanently
lighted, disconnect the connector of the E.C.U.
decoder and check if the indicator switches off;
- if the anti starting system is turned off,
c onnect the pin A5 of the wiring connector from
the E.C.U. decoder to an electric ground and
check if the indicator turns on.
Are the answers affirmatives?
