DISPOSAL
1. DISPOSE OF REAR SHOCK ABSORBER ASSEMBLY
LH
(a) Fully extend the shock absorber rod, and clamp it in
a vise at an angle.
(b) Using a drill, make a hole near the center of the
cylinder in the hatched area shown in the illustration
to discharge the gas inside.
CAUTION:
As metal debris may be blown outward by the
gas, you must:
• Wear protective glasses.
• Cover the area being cut.
NOTICE:
The gas is colorless, odorless and harmless.

DESCRIPTION
If a malfunction in the speed sensor signal circuit yaw rate sensor circuit occurs, the 4WD control ECU will
output this DTC.
INSPECTION PROCEDURE
HINT:
Check the condition of each related circuit connector before troubleshooting (see page IN-37).
(a) Clear the DTC (see page TF-16).
(b) Turn the ignition switch OFF.
(c) Turn the ignition switch ON again and check that CAN
communication system DTC(s) is not output.
(d) Drive the vehicle, accelerate to a speed of 20 km/h (12
mph) or more, and check if the speed sensor DTC (brake
control system DTC) is output (see page BC-57).
Result
HINT:
When DTCs indicating a CAN communication system
malfunction are output, repair the CAN communication
system before repairing each corresponding sensor.
B
C
A
(a) Replace the 4WD control ECU with a normally
functioning or new one.
(b) Reconfirm DTC.

(a) Using SST, remove the front drive shaft.
SST 09520-01010, 09520-24010 (09520-32040)
NOTICE:
• Be careful not to damage the transaxle case
oil seal, inboard joint boot and drive shaft
dust cover.
• Be careful not to drop the drive shaft.
17. REMOVE FRONT DRIVE SHAFT ASSEMBLY RH
(a) Remove the 2 bolts and pull out the drive shaft
together with the drive shaft bearing case.
(b) Remove the drive shaft from the transaxle.
NOTICE:
• Be careful not to damage the inboard joint
boot and drive shaft dust cover.

NOTICE:
The hub bearing could be damaged if it is subjected
to the vehicle weight, such as when moving the
vehicle with the drive shaft removed. Therefore, if it
is absolutely necessary to place the vehicle weight
on the hub bearing, first support it with SST.
