Cockpit Central Unit

DESCRIPTION

Cockpit central Unit is placed under the

dashboard, on the left side (in a protection box
(1).

Subject to vehicle’s equipment level, two

types of Cockpit Central Box may be
mounted:

- one type named  “ basic range”

(N2),

- one type named  “ high range” (N4).

OBSERVATION  :

Cockpit Central Unit type “high range” may

be mounted instead of Cockpit Central Unit
“basic range”

DISMOUNTING

REMARK:
- No  handling or intervention at the

protection box is allowed; in  case of damage,
replace the Cockpit Central Unit.

- Before dismounting, it is necessary the

reading of the Cockpit central Unit configuration.
Different UCH configurations may be performed
by means of the diagnostic tester.

Disconnect the battery (-) terminal.

Dismount:
- cockpit fuse box  cover
- attachment screw (A) of the Cockpit

Central Unit support.

Lift from attaching seat and take out the

assembly support-Cockpit Central Unit.

Carefully cut the attachment clip ( C) of the

protector (D).

Extract the assembly support – Cockpit

central Unit from protector.

Disconnect the UCH connectors.

Dismount Cockpit Central unit from

support (E).

REMOUNTING

Perform the dismounting  operations in the

reverse order; the protector and attachment
clip is to be  replaced.

ATTENTION!

At any intervention involving

dismounting of the assembly support-
Cockpit Central Unit, the protector and
attachment clip is to be replaced.

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 corresponding vehicle

special tools specified in the column “Necessary Special tools”.

GENERAL STEPS OF THE DIAGNOSTIC

- CLIP tester setting on, in order 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.
- Acknowledgement of the information supplied in chapters “General”.
- Reading of the memorised failure in the computer memory and taking advantage of the

chapter “Failures interpretation”.

ATTENTION : 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 are not to be applied on the vehicle unless the declared failure is interpreted in the
document for its specific memorising type. The memorising  type must be taken into consideration
when 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 diagnostic

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, because the
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
<<present failure  >  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.

NECESSARY SPECIAL TOOLS FOR INTERVENTION

- CLIP diagnostic tester
- All-purpose meter
