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.

Use the diagnostic tool to carry out a multiplex system test.
This check ensures that the various multiplex system connections are correct and finds any faulty segments.
Carry out any necessary repairs.
If the multiplex network test did not find the faulty connection, carry out a conformity check to check that the
status from the Protection and Switching Unit computer is present and correct (ET016, PR015, PR017).
Check the gearbox contacts.
If the status and parameters shown here are not correct, carry out fault finding on the Protection and Switching
Unit (see 87G, Engine compartment connection unit).
If the fault is still present, disconnect the Protection and Switching Unit computer connector to check that the
connector and its clips (terminals) are in good condition, especially the multiplex track clips (see the wiring
diagram of the Protection and Switching Unit fitted to the vehicle).
Replace the clips if necessary.

Fault finding – Conformity check37B
SUB-FUNCTION: AUTOMATIC RELEASE (CONTINUED 1)
NOTESOnly carry out this conformity check after carrying out a complete check using the
diagnostic tool.
Application conditions: ignition on (forced + after ignition, see Introduction)
Note:
The interpretation of these statuses and parameters is only valid with the
ignition switched on, the statuses and parameters displayed in blue on the
diagnostic tool is information supplied by other computers, which are transmitted via
the multiplex network. If these variables display inconsistent values, check that the
multiplex system test has not shown up any faulty connections. Repair the faulty
multiplex connections before looking for a possible problem with the signals.
Each sub-function in this test is associated with a Fault finding chart.
Special notes
The diagnostic tool may display the message Computer busy when displaying
statuses and parameters. This message is displayed when the parking brake is
applying or releasing the brake, because the computer gives priority to controlling the
motor before transmitting variables. If this message is displayed, exit the current
screen and then return to it.
