its thread and fill new specified oil as shown below by speci-
fied amount (roughly up to level hole).

OIL CHANGE
1) Before oil change or inspection, be sure to stop engine and
set vehicle horizontally.
2) Check oil level and existence of leakage. If leakage is found,
correct its cause.
3) Remove level/filler plug (2) and drain plug (1), then drain old
oil.
4) Install new gasket to drain plug and tighten drain plug to
specified torque.
Tightening torque
Rear differential oil drain plug
(a) : 55 N·m (5.5 kg-m, 40.0 lb-ft)
5) Fill proper amount of new gear oil as specified below
(roughly up to level hole).
6) Install new gasket to level/filler plug and tighten level/filler
plug to specified torque.
Tightening torque
Rear differential oil level/filler plug
(b) : 50 N·m (5.0 kg-m, 36.5 lb-ft)
Differential oil
: Hypoid gear oil API GL-5
For oil viscosity, refer to the chart.
Differential oil capacity
: 0.9 liters (1.9/1.6 US/Imp. pt)
NOTE:
 It is highly recommended to use SAE 80W-90 viscosity.
 Whenever vehicle is hoisted for any other service work
than oil change, also be sure to check for oil leakage.

DISMOUNTING
1) Hoist vehicle and remove wheels.
2) Drain oil from rear differential. (Refer to “OIL CHANGE” in
this section.)
3) Remove brake drum and disconnect parking brake cable
from brake back plate.
4) Remove axle shafts, refer to “REAR AXLE SHAFT AND

REMOUNTING
Reverse removal procedure for installation, noting the following.
Rear Differential
Clean mating surfaces of axle housing (1) and differential
carrier and apply sealant to housing side.
“A” : Sealant 9900-31110
Install differential carrier assembly to axle housing and
tighten carrier bolts to specified torque.
Tightening torque
Differential carrier bolts
(a) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
Install propeller shaft to joint flange aligning match marks (2)
and tighten propeller shaft bolts to specified torque.
Tightening torque

(b) : 23 N·m (2.3 kg-m, 17.0 lb-ft)
Rear Axle Shaft
For installation of rear axle shaft, refer to “REAR AXLE SHAFT
AND WHEEL BEARING INSTALLATION” in Section 3E.
Rear Brake Drum
For installation of rear brake drum, refer to “BRAKE DRUM
INSTALLATION” in Section 5.
Differential Gear Oil
Refill differential housing with new specified oil. Refer to “OIL
CHANGE” in this section for refill.
Brake Circuit Air Purging
Make sure to purge air out of brake circuit. Refer to “BLEEDING
BRAKES” in Section 5.
Then check to ensure that joint seam of pipe is free from oil leak.

ential carrier.1

8G-4 IMMOBILIZER CONTROL SYSTEM
ON-BOARD DIAGNOSTIC SYSTEM
(SELF-DIAGNOSIS FUNCTION)
Immobilizer Control Module and ECM diagnose troubles which
may occur in the area including the following parts when the igni-
tion switch is ON.
ECM :
ECM/Immobilizer Control Module code
Serial data link circuit
ECM
Immobilizer Control Module :
Transponder code
Coil antenna
ECM/Immobilizer Control Module code
Serial data link circuit
Immobilizer Control Module
Ignition signal
With the ignition switch turned ON (but the engine at stop) regard-
less of the condition of the engine and emission control system,
ECM indicates whether a trouble has occurred in the immobilizer
control system or not by causing the immobilizer indicator lamp to
flash or turn ON.
Immobilizer indicator lamp is ON :
No trouble exists in the immobilizer control system.
Immobilizer indicator lamp is flashing :
ECM or Immobilizer Control Module has detected some trouble in
the immobilizer control system.
When ECM and Immobilizer Control Module detects a trouble, it
stores DTC corresponding to the exact trouble area in ECM and
Immobilizer Control Module memory.
DTCs stored in memory of each controller (Immobilizer Control
Module and ECM) can be read by using the procedure described
in “DIAGNOSTIC TROUBLE CODE CHECK (IMMOBILIZER
CONTROL MODULE)” and “DIAGNOSTIC TROUBLE CODE
CHECK(ECM)” in this section. NOTE:
As soon as the ignition switch is turned ON, ECM and
Immobilizer Control Module diagnose if a trouble has
occurred in the immobilizer control system. While the
diagnosis is being made, the immobilizer indicator lamp
stays ON and if the diagnosis result is “abnormal”, it
immediately changes to flashing but if the result is “nor-
mal”, it remains ON. Diagnosis takes about 3 seconds at
maximum.
