IN THE EVENT OF A DISCHARGED BATTERY

M13506100102USA0000010000

If the ASC is not operating, the vehicle will be unstable
during braking, Do not drive the vehicle with the ASC-ECU
connector disconnected or with the ASC 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 ASC
consumes a large amount of current when carrying out its initial
checks. If this happens, recharge the battery fully.
