E-7Abnormality of motor drive circuit
[Explanation]The ABS ECU illuminates the warning light for the
motor relay and motor in the following cases.
l When the motor relay does not function
lWhen there is trouble with the motor itself and it
does not revolve
[Hint]If there is motor operation noise when wheel speed
exceeds
Gkm/h (4mph) when starting up after the
engine is started, there is a broken or short circuitedmotor monitor wire.

IFLAT BATTERY REMEDYNOWOAF
When booster cables are used to start the engine when the
battery is completely flat and then the vehicle is immediately
driven without waiting for the battery to recharge itself to some
extent, the engine may misfire, and driving might not be
possible. This happens because ABS consumes a great
amount of current for its self-check function; the remedy is to
either allow the battery to recharge sufficiently, or to discon-
nect the connector for ABS circuit, thus disabling ABS.
The ABS warning light will illuminate when the connector (for
ABS) is disconnected.
After the battery has sufficiently charged, connect the connec-
tor (for
ABS) and restart the engine; then check to be sure the
ABS warning light is not illuminated.
