VEHICLE SPEED
NOTESThere must be no present or stored faults.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2, Trafic II
ph2 or Kangoo 2.
Run fault finding on the ABS or ABS/ESP system, or on the vehicle speed computer depending on the equipment
level (see 38G, Vehicle speed computer or 38C, Anti-lock braking system).
If there are no faults on the ABS or ABS/ESP system, or on the vehicle speed computer, check the insulation,
continuity and the absence of interference resistance on the following connection:
–connection code 47F between components 261 and 118, 1094 or 953 depending on the equipment level.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
If the fault is still present, contact the techline.
AFTER REPAIRRepeat the conformity check from the start.

BATTERY VOLTAGE
NOTESThere must be no present or stored faults.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2, Trafic II
ph2 or Kangoo 2.
Check the permanent + supply fuse of component 261.
If the voltage is at minimum:
Check the battery and the charge circuit (see Technical Note 6014A Checking the charge circuit).
If the voltage is at maximum:
Check that the charging voltage is correct with and without electrical consumers switched on.
Check the insulation, continuity and the absence of interference resistance on the following connections:
Scénic II ph2:
–connection code BCP3 between components 261 and 260.
–connection code MT between component 261 and earth MT.
Espace IV ph2:
–connection code BCP4 between components 261 and 710.
–connection code MV between component 261 and earth MV.
Trafic II ph2:
–connection code BP26 between component 261 and the component supplying the LPN* radio
navigation computer.
–connection code MT between component 261 and earth MT.
Kangoo 2:
–connection code BP26 between components 261 and 260.
–connection code MT between component 261 and earth MT.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
AFTER REPAIRRepeat the conformity check from the start.

Fault finding - Command summary table
*LPN: Low Price NavigationNote:
To restart an activation session without switching the system off, run command RZ001 "Test parameters".
Tool command Diagnostic tool title Comments
RZ001Test parametersThis command is used to restart an
activation session without having to switch
off the system.
RZ003Fault memoryThis command is used to clear faults
stored in the navigation computer.
AC004Test right front speaker line
These commands are used to run a
listening test on each speaker and its
associated tweeter speaker (depending on
equipment level). AC005Test left front speaker line
AC006Test right rear speaker line
AC007Test left rear speaker line
AC009Screen test: colour barsThis command is used to check that the
video display is operating correctly.
Three colours are displayed on the screen:
Red, green and blue, and a black mosaic
on a white background.
AC010Microphone testThis command is used to check the
microphone connection.
The speakers transmit a tone and the
LPN* system checks the microphone input
signal.
AC011Detect Bluetooth space
AC013Eject CDThis command is used to eject the CD in
the LPN* radio navigation system.
VP001Write VIN
VP003Write After-Sales service date.

ALP 1 No dialogue with the LPN* computer
NOTESStart the engine.
Use the wiring diagrams Technical Note for Scénic II ph2, Espace IV ph2,
Trafic II ph2 or Kangoo 2.
Important: After activating the system, the delay before establishing dialogue can last
20 seconds.
Try the diagnostic tool on another vehicle.
Is dialogue possible with a computer?
YES NO
On the defective vehicle.
Check the voltage of the battery.
Check the condition and connection of the battery
connections.
Check the condition of the fuses.
Check:
–the connection between the diagnostic tool and
the diagnostic sensor (wiring in good condition),
–the connection between the diagnostic sensor
and the diagnostic socket (wiring in good
condition).
AFTER REPAIRCarry out a complete check with the diagnostic tool.
