REMEDY FOR A DISCHARGED BATTERY
If the engine is jump-started, because of a completely dis-
charged battery, the vehicle may suffer misfiring and fail to
start if an attempt is made to start without allowing the batterty
to recover
This is because the ABS consumes
a great deal of current for its self check. In such a case,
allow the battery to sufficiently charge or deactivate ABS
in the following manner.
to October,
Remove the ABS power relay in the engine compartment
to disable the ABS. Removing the ABS causes the ABS warn-
ing light to light. After the battery is charged sufficiently, install
the power relay and restart the engine to check that the
ABS warning light goes out.
<From November,
Disconnect the ABS-ECU connector. (Refer to
Removing the ABS causes the ABS warning light to light.
After the battery is charged sufficiently, connect the ABS-ECU
connector and restart the engine to check that the ABS warning
light goes out.
