Visual inspection of the sealing:
(Only for watertight connectors)
●Check for the seal on the connection (between the 2 parts of the connection).
●Check the seal at the back of the connectors:
–For unit joints (1 for each wire), check that the unit joints are present on each electrical wire and that
they are correctly positioned in the opening (level with the housing). Check that plugs are present on
openings which are not used.
–For a grommet seal (one seal which covers the entire internal surface of the connector), check that
the seal is present.
–For gel seals, check for gel in all of the openings without removing the excess or any protruding
sections (it does not matter if there is gel on the contacts).
–For hotmelt sealing (heat-shrink sheath with glue), check that the sheath has contracted correctly on
the rear of the connectors and electrical wires, and that the hardened glue comes out of the side of
the wire.
●Check that there is no damage to any of the seals (cuts, burns, significant deformation, etc.).
If a fault is detected, repair or replace the wiring (see Technical Note 6015A, Repairing electrical wiring, Wiring:
Precautions for repair)
5. FAULT FINDING LOG
You will always be asked for this log:
–when requesting technical assistance from Techline,
–for approval requests when replacing parts for which approval is mandatory,
–to be attached to monitored parts for which reimbursement is requested. The log is needed for
–warranty reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
–check the battery voltage to avoid incorrect operation of computer functions,
–use the proper tools.
It is forbidden to carry out a road test with the diagnostic tool in dialogue with the ECU because the ABS and
Electronic Brake Distribution functions are deactivated. Braking pressure is identical on both vehicle axles
(risk of a spin under heavy braking).IMPORTANTIMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG EACH TIME FAULT FINDING IS
CARRIED OUT.
