using SUZUKI scan tool. Before using scan tool, read
its Operator's (Instruction) Manual carefully to have
good understanding as to what functions are available
and how to use it.
• If the vehicles was operated in any of the following
ways, ABS warning lamp may light momentarily but
this does not indicate anything abnormal in ABS.

inspection and observe what is written there.
• Be sure to use the trouble diagnosis procedure as
described in "ABS Check: ". Failure to follow it may
result in incorrect diagnosis. (Some other diagnosis
trouble code may be stored by mistake in the memory
of ABS (ESP®) control module during inspection.)
• When disconnecting ABS hydraulic unit / control
module connector (1), pull down lock lever (2) of
