ON-VEHICLE SERVICE

ANTI-SKID BRAKING SYSTEM (ABS)

35B-63

IN THE EVENT OF A DISCHARGED 
BATTERY

M1352003500495

WARNING

If the ABS is not operating, the vehicle 
posture will be unstable during braking, Do 
not drive the vehicle with the ABS-ECU 
connector disconnected or with the ABS not 
operating for any other reason.

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.
