Fault finding - Introduction83A
Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of the faults should be considered when the diagnostic tool is switched on after the +
after ignition feed is switched on (with no system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Notes section.
If the fault is confirmed when the instructions are applied, the fault is present. Deal with the fault.
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool when the data
is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a
customer complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
–If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed
by Customer complaints.
A summary of the general procedure is provided in the form of a flow chart
on the following page.

NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after 60 seconds, with the ignition on.
Special notes:
Check the consistency between the instrument panel display and parameter PR035
Fuel level.
CO
NOTESSpecial note:
The fault is declared present if the fuel sender resistance is
greater than 350 Ω.
Manipulate the wiring harness between the instrument panel and the fuel sender in order to produce a change in
fault status (Present → Stored).
Look for possible damage to the harness, and check the connection and condition of the fuel sender and its
connections.
If there is a repair method (see Technical note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
Check the continuity of the following connections:
Fuel sender track 2 track 15, Grey instrument panel connector
Fuel sender track 4 track 2, Grey instrument panel connector
If there is a repair method (see Technical note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
Measure the resistance between tracks 4 and 2 of the fuel sender.
Replace the fuel sender if the resistance value is not: 290 Ω fuel tank in reserve
54 Ω fuel tank full
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESThe fault is declared present if the fuel sender resistance is
less than 5 Ω.
Manipulate the wiring harness between the instrument panel and the fuel sender in order to produce a change in
fault status (Present → Stored).
Look for possible damage to the harness, and check the connection and condition of the fuel sender and its
connections.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
Disconnect the fuel sender connector and check for a change in fault status.
If the fault remains in short circuit, check the insulation and continuity of the following connections, with the
connector disconnected:
Fuel sender connector track 2 track 15, Grey instrument panel connector
Fuel sender connector track 4 track 2, Grey instrument panel connector
If there is a repair method (see Technical note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair) repair the wiring, otherwise replace it.
If the fault becomes an open circuit fault, move to the next step of the fault finding.
Measure the resistance between tracks 4 and 2 of the fuel sender.
Replace the fuel sender if the resistance value is not: 290 Ω fuel tank in reserve
54 Ω fuel tank full
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
