WARNING
If the ABS is not operating, the vehicle will be unsta-
ble during braking, Do not drive the vehicle with the
ABS-ECU connector disconnected or with the ABS
not operating.
If the engine is started using a booster cable when the battery
is completely flat, and the vehicle is then driven without waiting
for the battery to be recharged, the engine may misfire and it
may not be possible to drive the vehicle. This is because the
ABS consumes a large amount of current when carrying out its
initial checks. If this happens, recharge the battery fully.
