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 faults should be taken into consideration when the diagnostic tool is used after the
+ after ignition feed (without activating the system components).
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 in the Notes section are applied, the fault is present. Deal with the
fault.
If the fault is not confirmed, check:
the electrical connections that correspond to the fault,
the connectors for this connection,
the resistance of the faulty component,
the condition of the wires.
Refer to paragraphs 4.1 Checking wiring and 4.2 Checking connectors
Conformity check
The aim of the conformity check is to check data which 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 repair.
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 permitted tolerance values, you should 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 dealt with by
customer complaints.
Asummary oftheoverall proc edure to follow isprovidedonthe fol lowing page in the form of a flow chart.

AFTER REPAIRClear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool
If the fault is still present, contact the Techline.

NOTESConditions for applying the fault finding procedure to stored faults:
Clear the stored fault, carry out a road test at a speed of > 36 mph (60 km/h) and test
the brakes using ABS.
Use the interpretation of the fault if it recurs.
Special notes:
The fault is detected if the computer does not detect a brake lights switch status change
for 4 acceleration/braking cycles and/or the contact is closed for over 6 minutes with
the vehicle speed above 24 mph (40 km/h).
Using the diagnostic tool, check on the status screen that ET017 Brake pedal recognises the correct pressed
and released positions of the brake pedal.
If the correct pedal position is not displayed, use the interpretation of ET017 Brake pedal.
