DESCRIPTION
CAUSE
ACTION
C21F2
SCM-XMR
System front
suspension valve
failure
Too many occurrence of
pressure pumping and
release in short delay
Front valve tube blocked
Blown valve fuse
Faulty valve block
Damaged circuit
wires or connectors
Faulty SCM
1- Disconnect the air line from the
front shocks. Go to Activations -
SCM and start Front Test routine. If
the air blows out of both shocks the
system is working properly. Check
the harness and connection to see
a potential source of intermittent
dysfunction, if nothing is found clear
the occurred fault and no more
actions have to be done. If the air
does not blow out even from one
shock continue to next action step.
2- Verify the air tubes (blue) from
the valves to both front shocks.
If clear go to next action step.
3- Unplug the valve block electrical
connector and verify that 12V is
present between pin B and battery
negative post (right) / between pin
C and battery negative post (left).
If not verify valve fuse, relay and
harness (refer to schematics for
more information). If both 12V
are read go to next action step.
4- Verify the front valves activation
by disconnecting the valve block
electrical connector and applying
12V across pin B and F (right) or C
and G (wrong in wire diagram) (left)
while compressor running (Go to
Activations - SCM and start Front
Test routine.). If the front valves are
opening and filling the shocks change
the SCM. If either of the front valves
are not opening, change the block
valve.
