SUSPENSION AND AXLE - A.D.D. CONTROL SYSTEM
SA2D4-01
INSPECTION
1. INSPECT A.D.D. ACTUATOR
(a) Disconnect the actuator connector.
(b) Measure the resistance between terminals 2 and 6.
Actuator side:
Standard resistance: 0.3 - 100
(c) Measure the resistance between terminal 2 or 6 and body
ground.
1 2 3 4 5 6 Standard resistance: More than 0.5 M
If the resistance value is not as specified, replace the actuator
assembly.
2. INSPECT A.D.D. ACTUATOR OPERATION
F06635 Apply battery positive voltage between terminals 2 and 6, and
check the actuator operation by sound, A.D.D. status and conti-
nuity between terminals 3 and 4.
Battery voltage A.D.D.
3 - 4 terminals continuity
applied terminal status
2 (+) - 6 (-) Continuity Connected
2 (-) - 6 (+) No continuity Disconnected
If the operation is not as specified, replace the actuator assem-
bly.
3. INSPECT LIMIT SWITCH CONTINUITY
(a) Connect the actuator connector.
2WD/4HI Switch (b) Push the 2WD/4HI switch and check that the 4WD indica-
tor light comes on after it is blinking.
(c) Check the A.D.D. actuator operation by sound.
(d) Disconnect the actuator connector.
(e) Check the continuity between each terminal, as shown in
the chart.
Tester connected terminal number Specified condition
1-3 No continuity
F19317
1-4 No continuity
3-5 Continuity
4-5 No continuity
(f) Connect the actuator connector.
SA-61
SUSPENSION AND AXLE - A.D.D. CONTROL SYSTEM
(g) Push the 2WD/4HI switch and check that the 4WD indica-
tor light goes off after it is blinking.
2WD/4HI Switch
(h) Check the A.D.D. actuator operation by sound.
(i) Disconnect the actuator connector.
(j) Check the continuity between each terminal, as shown in
the chart.
Tester connected terminal number Specified condition
1-3 Continuity
F16855
1-4 No continuity
3-5 No continuity
4-5 No continuity
(k) Connect the actuator connector.
4. INSPECT TRANSFER 4WD POSITION SWITCH
(See page TR-14)
5. REMOVE A.D.D. ACTUATOR (See page SA-41)
6. INSPECT CLUTCH HUB AND CLUTCH SLEEVE
(a) Check the clutch hub and clutch sleeve for wear and dam-
age.
If necessary, replace them.
(b) Check that clutch sleeve slides smoothly on the clutch
hub.
SA0356
7. MEASURE SLEEVE FORK AND CLUTCH SLEEVE
CLEARANCE
Using a feeler gauge, measure the clearance between the
sleeve fork and clutch sleeve.
Maximum clearance: 0.35 mm (0.0138 in.)
If the clearance exceeds the maximum, replace the fork or
sleeve.
