ACCOUSTIC WARNING - ANTI STARTING

All new decoders, are not coded. After mounting on the vehicle, it is necessary the memorisation
of the key head code by the decoder in order to be operational. If only the decoder is replaced, no
intervention is necessary to the injection computer, which will keep the old anti starting code. When
the vehicle is provided with RF remote control for blocking/unlocking the doors, the performing of
the resynchronisation of the keys with the decoder is imposed, after its mounting. If further to the
di ag nostic of the anti starting system, using the CLIP tester, the replacement of the decoder is
imposed, proceed as follows:
DISMOUNTIN G
- disconnect the (-) terminal of the battery;
- d ismount the ECU decoder-relays assembly;
- ro tate the ECU decoder assembly, in order to have access at its rear connectors;
- d isconnect the front wiring connector from the E.C.U. decoder;
- deta ch ECU decoder from clips of the relays-ECU decoder support.
REMOU NT I NG
- attach in clips the new E.C.U. decoder in the support, connect the front wiring connector to
the ECU decoder, then attach the assembly on the driving post cross member in its place and
mo unt its attachment screw;
- remo unt carefully the access flap of the fuse box;
- reconnect the (-) term inal of the battery.
Proceed then to the insertion of the anti starting code using the contact key, then to its me morising
(va lidation) in the E.C.U. decoder, using the CLIP tester. For this purpose, perform the “E.C.U.
decoder replacement procedure and anti starting code memorising”. Check then the correct operation
of the anti starting system with both keys.
ATTENTION!
Once the decoder has memorised the key codes, this code cannot be erased or replaced
with another one.
If it is necessary the replacement of the kit (E.C.U. decoder and two key heads), then the “ Kit
replacement procedure” must be performed.

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.

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?

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.
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

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 the
