During unloading of passengers and cargo
•When the vehicle height is higher than the
designated load level, oil flows back into the low-
pressure chamber from the high-pressure
chamber via the pump rod leveling port. As a
result, pressure in the high-pressure chamber
decreases, rod reaction force is reduced, and the
vehicle height returns to the designated load
level.

SUSPENSION CONTROL SYSTEM ON-VEHICLE INSPECTION (WGN)A6E7416010132021. Pull up the dust boot and visually inspect the piston rod for oil leakage.
2. Remove all cargo and drive the vehicle, with only the driver aboard, for 1 km {0.62 miles} or more. After
driving, verify that the rear vehicle height (distance measured from the fender brim to the center of the wheel) is
360 mm {14.2 in} or more
*. If not as specified, replace the rear shock absorbers.
3. Place a load equivalent to five people riding in
order to make the rear vehicle height to be 330
mm {13.0 in} or less.
4. Immediately after driving the vehicle for 5 km {3.0
miles} or more, under the same load conditions,
verify that the rear vehicle height is 335 mm {13.2
in} or more. If not as specified replace the rear
shock absorbers.
*: Indicates rear vehicle height with fuel tank full.
Height will vary 6—8 mm {0.24—0.31 in} between a
full and empty fuel tank.

Caution
•Performing the following procedures without first removing the ABS wheel-speed sensor may
possibly cause an open circuit in the harness if it is pulled by mistake. Before performing the
following procedures, remove the ABS wheel-speed sensor (axle side) and fix it to an appropriate
place where the sensor will not be pulled by mistake while servicing the vehicle.
1. Remove in the order indicated in the table.
2. Install in the reverse order of removal.

2. Using a 2—3 mm {0.08—0.12 in} drill bit, drill a
hole in the high-pressure side (area indicated by
A), and allow the gas to escape.
Warning
•The oil in the shock absorber is
pressurized and could spray out. Be sure
to drill slowly and carefully.
3. Using a 2—3 mm {0.08—0.12 in} drill bit, drill a
hole in the low-pressure side (area indicated by
B).
4. Place the shock absorber with the hole drilled in
Step 3 turned downwards. Move the piston rod up
and down several times to drain out the oil.
5. Cut the tube at the end of the shock absorber,
and completely drain the oil out.
6. Properly dispose of the waste oil according to
waste disposal laws.

ON-BOARD DIAGNOSTIC FUNCTIONA6E811155430205Outline
•The on-board diagnostic function is incorporated into the PCM, TCM, ABS (ABS/TCS) HU/CM (with ABS (ABS/
TCS)), DSC HU/CM (with DSC), 4WD control module, and instrument cluster. This function can narrow down
CAN system malfunction locations.
•Due to the adoption of the TCM and the 4WD CM, some DTCs and PID/data monitor items have been added.
Other functions are the same as those of the current Mazda6 (GG) model.

.
Fail-Safe Function
•When the failure detection function detemines that there is a malfunction, the fail-safe function illuminates a
warning light to advise the driver of the malfunction.
