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?

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 .
