Precautions in Diagnosing Troubles

To ensure that the trouble diagnosis is done accurately and smoothly, observe the following and follow "ABS Check".
• Diagnostic information stored in ABS control module memory can be cleared as well as checked by 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 vehicle was operated in any of the following ways, ABS warning light may light momentarily but this does not
indicate anything abnormal in ABS.
– The vehicle was driven with parking brake pulled.
– The vehicle was driven with brake dragging.
– The vehicle was stuck in mud, sand, etc.
– Wheel spin occurred while driving.
– Wheel(s) was rotated while the vehicle was jacked up.
• Be sure to read "Precautions for Electrical Circuit Service in Section 00" and "Precaution for CAN Communication
System in Section 00" before 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 control
module during inspection.)
• When disconnecting ABS hydraulic unit / control module connector (1), pull up lock lever (2) of connector.
When connecting, set the connector on ABS hydraulic unit / control module assembly and pull down the lock lever
(2) until it locks.
• Communication of ECM, BCM, combination meter, 4WD control module (if equipped), keyless start control module
(if equipped), TCM (if equipped), data link connector and ABS control module is established by CAN (Control Area
Network).
Therefore, be sure to read "Precautions for Installing Mobile Communication Equipment in Section 00" before
inspection and handling CAN communication line.

Precautions in On-Vehicle Service

When connector is connected to ABS hydraulic unit / control module assembly, do not disconnect connectors of
sensors with ignition switch ON. Otherwise, DTC will be set in ABS control module.
