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.

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.
