Check for shorted
actuator coil.
For code
146 s005 06
disconnect the recirc actuator
connector, check if fault no
longer active (different fault
maybe active).
For code
146 s006 06
disconnect the mode actuator
connector, check if fault no
longer active (different fault may
be active).
For code
146 s009 06
disconnect the temperature
actuator connector, check if fault
no longer active (different fault
may be active).
For code
200 s009 06
disconnect the temperature
actuator connector (auxiliary
unit), check if fault no longer
active (different fault may be
active). See
Fault no longer active
(FMI06), different fault
may be active (FMI
05).
Shorted actuator motor is likely.
Perform "Actuator Stepper Motor
Electrical Test" to confirm, then
go to test no. 9
.
Fault still active
(FMI06).
Check for short to ground in
power wire between actuator and
FCU/ACU. If no short is found,
replace FCU/ACU, then
go to
test no. 9
.
9
Verify repair.
NOTE: In order to
check if a fault status
has changed from
active to inactive, the
recirc button,
temperature control
switch, or air
selection switch
needs to be moved
while the ignition is
on.
Verify that repair resolved the
problem.
Problem resolved.
Done.
Problem unresolved.
Repeat test no. 1

Are evaporator
temperature sensor
fault codes active?
Check if fault code
146 s002 03
or
146 s002 04
is active.
Neither fault isactive.
Go to test no. 2
.
146 s002 03
is active
Check for sensor signal wire
shorted to power. If okay,
go to
test no. 2
.
146 s002 04
is active.
Check for sensor signal wire
shorted to ground. If okay,
replace FCU.
Go to test no. 3
