Vacuum Advance
1. Warm up the engine to the normal operating tem-
perature.
2. Check that the idle speed and ignition timing are
correct.
3. Disconnect the vacuum hoses from the vacuum
control unit, and plug them.
4. Connect a vacuum pump to the vacuum control
unit.

ALTERNATOR 5
Warning
Disconnect the nagative battery terminal when disconnect or reconnect B terminal.
TEST 1
1. Disconnect the alternator connector (2-pin).
2. Connect the SST.
4. Connect the red clip of the adapter harness to the battery
(
+
),
and check that the red
lamp and green lamp illuminate.
5. Start the engine and check that both lamps go off.

TEST 2
1. Connect an ammeter (75A min.) between the wire and the B terminal.
2. Turn all headlights and accessories on, and depress the brake pedal.
3. Start the engine and check that output current is 70A (RF-CX: 75A) or more at
2,500—3,000 rpm of the engine speed.
Caution
Do not ground the B terminal.

Inspection
1. Check that engine starts only at P and N range.
2. Check that the backup lights illuminate in R range
with the ignition switch ON.
3. If the inhibitor switch is not operating properly, dis-
connect it and check the continuity between the
terminals.

(8) The center position can be determined from
the left/right measurements in (5) and (7) above.
Example:
Right rotation.... 10 mm (0.39 in)
Left rotation....8 mm (0.31 in)
Center = Right 1 mm (0.04 in)
(9) Check that the center is within specification.

(10) If not correct, adjust the steering angle trans-
fer shaft.
2. Steering Inspection
With the vehicle stopped and the engine running,
check that the rear wheels turn in the opposite
direction when the steering wheel is turned and that
there is no abnormal noise.
86U10X-310
3.4WS Electric System Inspection
Drive the vehicle and check that the 4WS warning
light does not come on at over 40 km/h (25mph).

Checking Condition
Condition A
1. Turn the ignition switch OFF.
2. Start the engine and let it idle.
3. Turn the steering wheel to the straight-ahead po-
sition, and check the output pattern.
Refer to page 10—89 for other patterns and indi-
cated failure points.
Condition B
1. Turn the ignition switch OFF.
2. Start the engine and let it idle.
3. Turn the steering wheel 45° left and right from the
center, and check the output pattern.
Refer to page 10—89 for other patterns and indi-
cated failure points.
Condition C
1. Turn the ignition switch OFF.
2. Place the vehicle on a chassis roller tester. Block
the rear wheels, and secure it with chains.
3. Start the engine. Put the transmission in gear and
operate the vehicle at more than 10 km/h (6.2
mph).
4.Check the output pattern.
