ABS <4WD> -On-vehicle Service35B-31
WHEN THE BATTERY IS FLAT
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.
Caution
The vehicle posture will be unstable during braking, so
do not drive the vehicle with the ABS-ECU connector
disconnected or with the ABS not operating for any other
reason.
