ACTIVE STABILITY CONTROL SYSTEM (ASC)
35C-140
IN THE EVENT OF A DISCHARGED 12V STARTER BATTERY
M1355006200287
WARNING
If the ASC is not operating, the vehicle will be
unstable during braking, Do not drive the
vehicle with the ASC-ECU connector discon-
nected or with the ASC not operating.
If the electric motor unit is started using a booster
cable when the 12V Starter battery is completely flat,
and the vehicle is then driven without waiting for the
12V Starter battery to be recharged, the electric
motor unit 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 12V Starter
battery fully.
