[Comment]When power is supplied to the ABS-ECU, the valve relay changes from to OFF ON by the initial check, and thus even if there is a problem with the circuit betweenABS warning light and ABS-ECU, the light will illum inate once when the valve relayis OFF.Accordingly, the cause of the light not illuminating is probably an open circuit in the
light power circuit, a blown light bulb, or an open circuit in both the circuit between
the ABS

REMEDY FOR A FLAT ,35200350072
When booster cables are used to start the engine wh en the’
battery is completely flat and then the vehicle is
driven without waiting for the battery to
some extent, the engine may misfire, and driving not
be possible.
This happens because ABS consumes a great of’
current for its self-check function; the remedy is to either
allow the battery to recharge sufficiently, or to r emove the,
fusible link for ABS circuit, thus disabling the an ti-skid brake
system.
The ABS warning light will illuminate the fusible
(for is removes.
After the battery has sufficiently charged, install the fusible
link (for ABS) and restart the engine; then check t o be sure
the ABS warning light is not illuminated.

GENERAL
OPERATION
Low-speed (and high-speed) wiper operation
l When the wiper switch is placed in the LO
position with the ignition switch in the ACC
or ON position, wipers operate continuously
at low speed.
l Placing the wiper switch in the HI position
causes the wipers to operate at high speed.
Auto wiper stop operation
lWhen the wiper switch is placed in the OFF position, the cam contacts of wiper motor
causes current to flow through the auto wiper
stop circuit, allowing the wiper blades to cycle
before they reach to the stop positions.
Intermittent wiper operation
l When the wiper switch is placed in the
position with the ignition switch in ACC or ON
position,the intermittent wiper relay is
energized causing the intermittent wiper relay
contacts to close and open repeatedly.
lWhen the contacts are closed, motor
is energized.
lWhen the wiper motor is energized, the
contacts open; however, the
the wiper motor energized until the wiper
return to their stop position.
