Procedure (continued)
Espace IV ph2: To save energy, the UCH on the Espace IV Phase 2 cuts out the + after ignition feed after
3 minutes.
To run fault finding on a computer, it is possible to force the + after ignition feed for 1 hour by applying the following
procedure:
–Press the card unlocking button.
–Insert the card into the 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 on for 1 hour.
Pressing the Start button or removing the card from the card reader cuts off the + after ignition feed but does not cut
off the forced after ignition feed timed mode. Until one hour has elapsed, activating the + after ignition feed will
restart 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 after the
+ after ignition feed is switched on (without acting on the system components).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions 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 faulty,
–the condition of the wires (melted or split insulation, wear).
