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.

After-repair Procedure
1. Cancel the memory of malfunctions by disconnect-
ing the negative battery terminal for at least five sec-
onds, then reconnect it.
2. Remove the EC-AT tester if it is connected.
3. Drive the vehicle at 50 km/h (31 mph), then de-
press the accelerator pedal fully to activate kick-
down. Stop the vehicle gradually.

ABS WARNING LIGHT
Inspection for No Illumination
1. Check that other warning lights illuminate. If not,
check the METER 10A fuse for burning out.
2. Turn the ignition switch ON.
3. Ground the LY terminal
of
the check connector with
a jumper wire.
4. Check that the ABS warning light illuminates.
If not illuminated, check the bulb and harness (bat-
tery -» check connector).
5. Check for 12V at F (LY) terminal of the control unit
connector.
If the voltage is not as specified, check the harness
(bulb control unit).
If the voltage is as specified, replace the relay box
and the control unit.
RELAY BOX
Inspection of Fail-safe Relay
1. Check for continuity of the relay with an ohmmeter.
Replace the relay box if necessary.
