Check the vehicle gearbox configuration: check that the configuration is not for a manual gearbox when the
vehicle is fitted with an automatic transmission, or that it is not configured for an automatic transmission when the
vehicle is manual.
Using the diagnostic tool, run fault finding on the multiplex system and particularly on the automatic
transmission computer-parking brake control unit segment.
This check ensures that the various multiplex system connections are correct and finds any faulty segments.
Carry out any necessary repairs.
If the multiplex system test did not find the faulty connection, carry out a conformity check to check that the
status coming from the automatic transmission computer is present and correct (ET018).
If status ET018 is not correct, carry out fault finding on the automatic transmission.
If the fault is still present, disconnect the automatic transmission computer connector to check that it is sound as
well as its clips (terminals), and in particular the clips for the multiplex tracks (refer to the wiring diagram for the
automatic transmission computer fitted on the vehicle).
Replace the clips if necessary.
If the fault persists, contact the Techline.
AFTER REPAIRIf the computer has been replaced (at the request of the Techline), initialise the
electronic parking brake computer (see Replacement of components).
Issue several braking and release commands to confirm the repair.
Deal with any other faults.
