3. REMINDERS

Faults:

There are current faults (occurred under certain conditions and still present) and stored faults (occurred under certain conditions and no longer present).

For a present fault, deal with the fault following the procedure given in the chapter "Fault interpretation".

For a stored fault, note the displayed faults and follow the instructions in the "Instructions" section.

If the fault is confirmed by the "Instructions" section, the fault is present again. In this case, repair the fault.

If the fault is not confirmed by the "Instructions" section, carry out the basic checks. To do so, check:

  • The electrical wiring related to the fault.
  • The connectors of these circuits (corrosion, bent pins, etc.).
  • The resistance of the component identified as faulty.
  • The condition of the wiring (melted or cut insulation, chafing).

Conformity check

The conformity check aims to verify the states and parameters that show no fault on the diagnostic tool when they are inconsistent. This step therefore allows you to:

  • To diagnose faults with no fault displayed that may correspond to a customer complaint.
  • To check correct system operation and make sure a fault will not reappear after the repair.

This chapter therefore contains a diagnosis of states and parameters, under the conditions required for their check.

If a state does not operate normally or a parameter is out of tolerance, refer to the corresponding diagnostic page.

Customer complaints - Fault locating tree

If the diagnostic tool check is correct but the customer complaint is still present, treat the problem as a "customer symptom".

A summary of the overall procedure is shown as a flowchart on the next page.

Préliminaires

5. DIAGNOSTIC SHEET

CAUTION:

All incidents on a complex system must be subject to a full diagnosis using suitable tools. The DIAGNOSTIC SHEET, to be completed during diagnosis, provides and keeps a record of the diagnosis carried out. It is an essential element of communication with the manufacturer.

A DIAGNOSTIC SHEET MUST BE COMPLETED EVERY TIME A DIAGNOSIS IS PERFORMED.

This sheet will always be requested:

  • When requesting technical assistance from the techline.
  • For APPROVAL requests, when replacing parts that require mandatory approval.
  • To be attached to the "monitored" parts returned. It is then required for warranty reimbursement and helps with a better analysis of the removed parts.

6. SAFETY INSTRUCTIONS

Any operation on a component requires compliance with safety rules to avoid any material damage or personal injury:

  • Check that the battery is correctly charged to avoid damage to the ECUs in case of low charge.
  • No smoking.
  • Use the appropriate tools.
