INSTALLATION OF XR25 DIALOGUE / DECODER UNIT
- Connect the XR25 to the diagnostic socket.
- ISO selector on S8
- Enter D56 n.56
PRECAUTION :
When carrying out the test using a multimeter, avoid using a test pin on connectors where the test pin is
of a size which could damage the clips and lead to a poor contact.
Pay attention to parts numbers on wrenches.
ERASING THE MEMORY
After repairing the immobiliser system, enter G0** on the keyboard of the XR25 kit to proceed with
erasing the memorised fault.

Using the XR25 kit, correctly reconfigure the decoder unit.
On the XR25 keyboard, enter G22*1* for a petrol vehicle
or G22*2* for a diesel vehicle
NOTE: In the diesel version, incorrect configuration of the decoder unit does not prevent proper
operation of the immobiliser. Nevertheless, if there is a fault, the immobiliser warning light will
not illuminate.

Set the XR25 to pulse sensor mode (button "G", input on terminal "Vin").
Ignition on, check for pulses on track A6 of the 18 track decoder unit connector (test with the decoder
unit and the coded electronic unit of the solenoid valve connectors connected).
Ignition on, if there are no pulses, change the decoder unit.
Switch on the ignition for 30 consecutive seconds, then switch off the ignition and wait until the
immobiliser warning light flashes (immobiliser active).
Switch on the ignition again and check that bargraph 8 left hand side is permanently illuminated.

For the diesel version, if bargraphs 6 right and 6 left are illuminated, check the impact switch.
Check the condition of the electrical wiring between track A6 of the decoder unit and track 8 of the
coded solenoid valve connector and check the 12 Volts supply and earth.
Repair if necessary.

If the problem persists, replace the antenna ring.
Check that the antenna ring is properly fed with earth on track 2 and 12 Volts on track 3.
Disconnect the 4 track antenna ring connector.
Set the XR25 to pulse sensor mode (button "G", input on terminal "Vin").

If BG 17right is illuminated, do not apply the following fault finding as the
decoder unit is new. Carry out the Plip programming procedure.
Only consult the following fault finding if BG 11 left remains extinguished after
having tried to lock or unlock the vehicle doors with the PLIP .
NOTES
Fiche n° 56
Check if locking or unlocking the doors is possible by testing with the other key. If locking or unlocking of
the vehicle doors is possible, replace the battery in the first key.
On the infrared transmitter connector, check for + 12 V before ignition feed between tracks B2 and A3.
Is this voltage present ?
Set the XR25 to pulse sensor mode (button "G", input on terminal "Vin").
Check for pulses on track B2 of the infrared transmitter by pressing the PLIP (test
with the decoder unit and infrared transmitter connectors connected).
Are there any pulses when the PLIP is pressed?YES
YES Replace the decoder unit.
