Diagnostic – general
This document is presenting the diagnostic generally valid for all computers, for Cockpit
Central Unit function, at SOLENZA vehicles all types of engine
In order to perform the diagnostic of this system, it is then all-important to dispose of the
following elements:
- workshop manual of the corresponding vehicle
-electric diagram of the function, for the correspondin g vehicle
special tools specified in the column “Necessar y Special tools”.
GENERAL STEPS OF THE DIAGNOSTIC
- CLIP tester setting on, in orde r to identify the system that is equipping the vehicle
(identification of the computer family , program number, V. diagnostic..).
- Analysis of the “diagnostic” documents corresponding to the identified system.
- Acknowledgemen t of the information supplied in chapters “General”.
- Reading of the memorised failure in the computer memory and taking advantage of the
chapter “Failures interpretation”.
A TTENTION : each failure is interpreted for a specific type of memorisation : present failure
memorised failure present or memorised failure). The specified checking for handling each
failure a re not to be a pplied on the vehicle unless the declare d failure is i nterpre ted in t he
document for its specific memorising type. The memorising type must be taken into consideration
w hen the tester is set on after setting off and on of the contact .
If a failure is interpreted in the moment when it is declared “memorised”, the di agnostic
application conditions are present in “Recommendations”. If the conditions are not fulfilled, you
must take the ideas from the diagnostic of damaged element circuit checking, be cause t he
failure is not anymore present on the vehicle. Apply the same method when a failure is declared
as been memorised by the diagnostic tester, but it is interpreted in the documentation only as
< state.
- Performing the conformity checking (accentuation of the possible failures, non-declared
yet by the system self-diagnostic) and application of the adequate diagnostic according to the
results.
- Reparation validation (elimination of “client’s effect”)
- Diagnostic exploitation by “Client’s effect” if the problem still on.
N ECESSARY SPECIAL TOOLS FOR INTERVENTION

MEMORIZED WINDSCREEN WIPER FIX POINT STOPPING
Diagnostic application conditions to the memorized failure:
RECOMMENDATIONS - failure declared present further to wiper control
REMARK: wipers random operation in timing position
(timing non-respected)
Check that fix point stopping state ET 005 is active each time when wipers blades reach the
pause position and then pass to inactive.
Check the branching and the state of connectors of the Cockpit Central Unit.
Replace the connector, if necessary.
Check the insulation , continuity and absence of parasite resistance of lines:
Pin A6 of UCH connector P1 pin 2 windscreen wiper motor
Mass pin 1 windscreen wiper motor
Fix if necessary.
Check connection and condition of the connector of the windscreen wiper motor
Check the windscreen wiper motor
Check the windscreen wiper mounting
Replace, eventually, the wiper motor.
Apply the recommendation
AFTER REPAIRING Fix all others failures
Erase the memorized failures.

RECOMMENDATIONS Check that no failure is be present or memorized.Open the drivers’ door
Check that for open door the corresponding state is active or for closed door, the
corresponding state is inactive
Check continuity and insulation of the wiring between:
Dr iver’s doors contact and pin 40B of UCH connector EH1
Fix if necessary (see electric diagram of that vehicle)
O pen the door.
Check continuity between mass and pin 40B of UCH
Close the door and check that no continuity is between mass and pin 40B of UCH
In case of a failure, replace the driver’s door contact.
Perform again a system diagnostic
Repair the other possible failures
Erase the memorized failures.

APPLICATION CONDITIONS OF THE CHECKING DEFINED
AT DIAGNOSTIC
Each failure is interpreted for a specific memorizing type (present failure, memorized failure,
memorized or present failure).
The defined checking for each failure tracing is not to be applied unless the failure is interpreted
for the failure type declared by the CLIP tester.
If a failure is not interpreted in diagnostic or it is declared “present”, the diagnostic application
when the failure is only “memorized” will not allow the location of the memorizing origin of that
failure.
In this case, only a wiring and respective element connector checking must be performed (it
is recommended the wiring movement in order to try the passing visualization from state
“memorized failure” to state “present failure”).
If a failure is interpreted when it is declared “memorized”, the confirmation conditions of the
failure real presence (and the necessity of diagnostic application) are to be found at
”Recommendations” or at the beginning of the failure interpretation.
REMARK:
Before releasing diagnostic, the cont act must be off.
AT T E N T I O N !
Before any intervention at t he airbag system, i t i s obligatory t he UCE airbag blocking
by means of the CLIP tester, using the control “Computer blocking”. The confirmation
of this cont rol perform ing will be visual ized by permane nt lighting of the airbag
indicator from instrument panel and t he releasing line will be blocked, av oiding i n
this way the undesirable releasing of t he airbag during the intervention.
AT T E N T I O N !
〈〈〈〈If
the intervention is taking place after the vehicle has suffered a collision followed
by the driver’s airbag releasing, UCE airbag blocking is possible only after performing
its unblocking control performing.
〈〈 〈〈Further to a shock causing the airbag releasing, the erasing of the memorized
failures it is possible only after dat a reading from “Imp act context”, followed by
“Computer unblocking” control.
〈〈 〈〈The electrical measurements on the airbag releasing l ine are t o be pe rformed
only by using the function “ Airbag beam t ests” of the CL IP tester. It is strictly forbidden
the use in this purpose of the ohmmeter type measurement devices.
〈〈 〈〈Before using the inert igniter, check that its resistance is between 1.8 – 2.5 ¿.
〈〈〈〈Ensure that during intervention, the computer supply voltage is not less than
10 V.

The presence of this failure is correspo nding to an incoherence between the computer configuration

INTERPRETATION OF CONNECTORSWIRES FUNCTION INDEX
The information concerning the function of the wires in connectors and connections
included in chapter 11, are to be interpreted taking into account the explanations based upon
the following example:
1 = symbol (sign) of the page containing connectors and electric connections
2 = connector destination
3 = name of the wiring on which the respective connector is placed
4 = general criteria of page separation
5 = vehicle class
6 = manufacturing year
7 = connector code
8 = component identification to whom the described connector is to be connected
9 = connector c olour
10 = connector symbol
11 = indication of the connector socket
12 = wire sectioning (mm˝)
13 = wire functional code
14 = wire destination
15 = wire colour *
16 = chapter number and connector page number
REMARK:
Concerning position 15, please note that one X is marked, for one wire and two Xs for
two wires. The colour of the wire is to be symbolised only in case the electric routing of the
wi re represents one of the fundamental statuses: + permanent (+ IC), + after contact (+ DC),
mass (-) or controls.
The symbols used for the wire colours are the followings:
A = white AS = blue GR = grey
N = black G = yellow V = green
M = brown VI = violet R = red

plug, the following symbols are to be used:
