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).
