Fault finding - Introduction86A
Procedure (continued)
Espace IV ph2:
In order to save energy, the Espace IV Phase 2 UCH cuts off the + after ignition feed after 3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed on for 1 hour by applying the
following procedure:
–Press the card unlocking button.
–Insert the card into the card reader.
–Press the Start button (interrupting the timed + after ignition feed mode).
–Press and hold the start button for over 5 seconds until the engine immobiliser warning light starts to
flash rapidly (4 Hz).
This "forced + after ignition feed" mode remains active for 1 hour.
Pressing the start button or removing the card from the reader cuts off the forced + after ignition feed but does not cut
off the timed forced + after ignition feed mode. As long as one hour has not passed, the + after ignition feed function
restarts the forced + after ignition feed for the remaining time.
Trafic II ph2 and Kangoo 2:
To run fault finding on the vehicle computers, switch on the forced + after ignition feed.
Faults
Faults are displayed as present or stored (they appeared in a certain context and have since disappeared, or they
are still present but cannot be diagnosed in the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is used following
the + after ignition supply being switched on (without operating the system components).
For a present fault, apply the method described in the section on Interpretation of faults.
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 lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the component detected as defective,
–the condition of the wires (melted or split insulation, wear).

4. FAULT FINDING PROCEDURE (CONTINUED)
Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring harness may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Tactile inspection
While manipulating the wiring harness, use the diagnostic tool to note any change in fault status from stored to
present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or to another wire.
If a fault is detected, repair or replace the wiring harness.

Fault finding - Replacement of components
For information on removing/refitting the LPN* radio navigation computer, refer to the MR for the vehicle concerned:
–Scénic II ph2 (see MR 370, Mechanical, 83C On-board telematics system, Navigation computer: Removal -
Refitting)
–Espace IV ph2 (see MR 405, Mechanical, 83C, On-board telematics system, Radio navigation:
Removal - Refitting)
–Trafic II ph2 (see MR 408, Mechanical, 83C, On-board telematics system, Radio navigation:
Removal - Refitting)
–Kangoo 2 (see MR 417, Mechanical, 83C On-board telematics system, Radio navigation:
Removal - Refitting)
Operations to be carried out before replacing the LPN* radio navigation computer:
Note:
If the LPN* radio navigation computer and the multimedia network interface unit are replaced
simultaneously, first configure the multimedia network interface unit (see 86D, multimedia network interface
unit, Configuration and programming).
1 -Before replacing the LPN* radio navigation computer (with Techline approval), perform a fault read and a
conformity check to confirm that it is defective.
2 -Before removing, eject the CD.
3 -After obtaining Techline approval, remove the LPN* radio navigation computer with the ignition off (wait
1 minute for the system to shut down completely).
The LPN* radio navigation computers available from the Parts Department are supplied unconfigured.
Operations to be carried out after replacing the LPN* radio navigation computer:
1. Configure the computer (see Configurations and Programming).
The LPN* radio navigation computer is in factory mode following configuration (FM 87.5 MHz in scrambled mode for
2 minutes).
Clear the present or stored faults using command RZ003 Fault memory.
2. Enter the unlocking code for the LPN* radio navigation system
How to obtain the unlocking code for the LPN* radio navigation system:
–switch on + after ignition feed (see Introduction),
–if the LPN* radio navigation system does not switch on when the + after ignition feed is activated, press the ON/
OFF button on the front panel,
–connect the Clip diagnostic tool,
–note the programming key number ID007 Radio programming key shown in the Identification menu.
–When you have this programming key number, consult Renault.net to obtain the LPN* radio navigation system
unlocking code. If the fault is still present, contact Techline.
–The unlocking code is requested 2 minutes after the LPN* radio navigation system has been switched on,
–enter the code using the radio control satellite under the steering wheel.
Important: After activating the system, the delay before establishing dialogue can last 20 seconds.
*LPN: Low Price NavigationNote:
Each time an incorrect code is entered, the waiting time doubles (maximum 32 minutes).
