FA ILURES AND STATES INTERPRETATION
1. FAILURE OF COMMUNICATION CLIP TESTER/ E.C.U. DECODER
RECOMMENDATION Check if the lines K and L are not disturbed by another computer of the vehicle.
Check the condition of fuse F 03 from the cockpit fuse box.
Replace the fuse if necessary.
Check if the CLIP tester is not the cause of the failure; check if the tester is communicating
with another computer of the same vehicle (injection computer).
M easure the tension of the vehicle’s battery (U> 12,3V). If necessary, charge the battery.
Check if the E.C.U. decoder is correctly connected to the vehicle’s wiring.
Check the right supply of the E.C.U. decoder:
-presence of the mass at pin A8 of the E .C.U. decoder
- supply + I.C. at pin A9 of t he E .C.U. decoder
Be sure that the diagnostic socket i s proper supplied, according to the circuit diagram.
Check the continuity and the isolation of the electric wiring on the corresponding pins layout.
E.C.U. decoder A3 7 diagnostic socket
A4 15
If the connection tester CLIP – E.C.U. decoder can’t be established, then replace the decoder.
AFTER REPAIRING After establishing the communication with the tester, fix the
possible failures.
Perform a conformity checking.

2. 4D STATE: + 12 V (+DC) SUPPLY, EXISTENT
RECOMMENDATION Observation : - 4D state = ACTIVE when the contact i s on “M” position;
- 4D state = PASSIVE when the contact is not on “M ”position.
AFTER REPAIRING Perform a conformity checking.
Check the operation of the anti starting system.
YES
NO Replace the E.C.U. decoder if its communication with t he tester can not be realised.
Repair the electric wiring on the supply layout to the pin A7 of E.C.U. decoder.
Check the F03 fuse condition.
Replace the fuse if necessary.
Place the contact on “M” position and check the presence of +12V at the pin A7 of the
E.C.U. decoder. Is there +12V?

the E .C.U. decoder PinA6 pin58 injection computer.
Fix it if necessary.
.
Set t he contact on and perform the detection test using the CLIP tester at pin A 6 of the ECU
decoder.
Are there any impulses?
YES

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.
Di sconnect 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
NO Replace the anti starting bushing.
Replace t he E.C.U. decoder.
Remove the memorised
failures by means of the CLIP tester.
AFTER REPAIRING Perform a conformity checking.

6. STATE 11G: ACTIVATE THE RF REMOTE CONTROL/ RECEIVED RF SIGNAL
IN DICATION
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
PA SSIVE when activating the RF remote c ontrol 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 ?
Pe rform using the CLIP tester, the impulse de tection 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.
NO Replace the anti starting bushing.YES
Check the isolation related to the mass of the electric wiring between:
E.C.U. decoder Pin B1 pol e 1 anti start ing bushi ng Pin B2 pole 1 door locking switch
Pin B5 pole 5
Isolation against mass is good?
YES Fix the electric wiring.
NO Replace the E.C.U. decoder
.
NO
AFTER REPAIRING Perform a conformity checking.

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 a nd 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.

A LP1. MISSING COMMUNICATION CLIP TESTER / E.C.U DECODER
RECOMMENDATION Check if the lines K a nd L are not perturbed by another computer
of the vehicle.
Check the condition of the F03, F04 fuses from cockpit fuse box.
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>12,3V). 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 : - mass 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.
