DIAG 17ANTIPERCOLATION RELAYFiche n° 27
XR25 aid:The fan assembly must operate when command mode G17* is used.
No fault bargraphs should be illuminated.
NOTES
The antipercolation relay
does not click when its
command mode is used
There is 12 V
on track 1
Ignition on, check for 12 V on track 1 of the fan assembly relay.
There is not 12 V
on track 1Check the line for track 1 of the relay to the fuse.
The antipercolation relay
does click when its
command mode is usedFan assembly relay in place, check, during operation of the command mode,
for 12 V on track 5 of the fan assembly relay.
There is not 12 V
on track 5Check the insulation and continuity of line 3 on the
relay to the fuse.
Repair if necessary.
The fault persists, replace the fan assembly relay.
There is 12 V
on track 5
If the fan assembly still does not operate, replace the
fan assembly.
The fault persists, replace the relay.
The fault persists!
Replace the injection computer.
