WARNING:
For vehicles equipped with Supplemental Restraint (Air Bag) System:
Service on and around the air bag system components or wiring must be performed only by an
authorized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under
“General Description” in air bag system section in order to confirm whether you are performing ser-
vice on or near the air bag system components or wiring. Please observe all WARNINGS and “Ser-
vice Precautions” under “On-Vehicle Service” in air bag system section before performing service
on or around the air bag system components or wiring. Failure to follow WARNINGS could result in
unintentional activation of the system or could render the system inoperative. Either of these two
conditions may result in severe injury.
Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system
may be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
NOTE:
For the description (items) not found in this section refer to the same section of the Service Manual
mentioned in the FOREWORD of this manual.
When inspecting and servicing vehicle equipped with ABS, be sure to refer to section 5E2 first.
All brake fasteners are important attaching parts in that they could affect the performance of vital
parts and systems, and/or could result in major repair expense. They must be replaced with one of
same part number or with an equivalent part if replacement becomes necessary. Do not use a
replacement part of lesser quality or substitute design. Torque values must be used as specified
during reassembly to assure proper retention of all parts. There is to be no welding as it may result
in extensive damage and weakening of the metal.

ANTILOCK BRAKE SYSTEM (ABS) 5E2-25
DTC C1057 (DTC 57) – Power Source Circuit
DESCRIPTION
The ABS control module monitors the power source voltage at terminal “E136-18”. When the power source volt-
age becomes extremely high or low, this DTC will be set. As soon as the voltage rises or lowers to the specified
level, the set DTC will be cleared.
INSPECTION
1. Ignition switch 3. ABS hydraulic unit/control module assembly
2. Main fuse 4. ABS hydraulic unit/control module connector
Step Action Yes No
1 1) Connect a voltmeter between battery posi-
tive (+) terminal and body ground.
2) Start the engine and measure the maximum
voltage when racing the engine.
Is it over 18V?Check charging system
referring to “CHARGING
SYSTEM” section.Go to Step 2.
2 1) Disconnect ABS hydraulic unit/control mod-
ule connector.
2) Keep the engine idling, measure the voltage
between terminal “E136-18” of ABS control
module and body ground.
Is it always under 9V?Check charging system
referring to “CHARGING
SYSTEM” section.
Imperfect short between
wire “GRN/ORN” and
ground.Poor connection of termi-
nal “E136-18” or “E136-
24” of the ABS control
module.
If the above are in good
condition, substitute a
known-good ABS hydrau-
lic unit/control module and
recheck.

ANTILOCK BRAKE SYSTEM (ABS) 5E2-27
DTC C1063 (DTC 63) – ABS Fail-Safe Relay Circuit
DESCRIPTION
ABS control module monitors the voltage at the terminal of solenoid circuit constantly with ignition switch turned
ON. Also, immediately after ignition switch is turned ON, perform initial check as follows.
Switch fail-safe relay in the order of OFF → ON and check if voltage changes to Low → High. If anything faulty is
found in the initial check and when the voltage is low with ignition switch turned ON, this DTC will be set.
INSPECTION
1. Ignition switch 3. ABS hydraulic unit/control module connector 5. Fail-safe relay
2. ABS hydraulic unit/control module assembly 4. To solenoid valves
Step Action Yes No
1 Check battery voltage. Is it about 11 V or
higher?Go to Step 2. Check charging system
referring to “CHARGING
SYSTEM” section.
2 Check ABS main fuse and connection.
Is it in good condition?Go to Step 3. Repair and/or replace
fuse.
3 1) Ignition switch OFF.
2) Disconnect ABS hydraulic unit/control mod-
ule connector.
3) Check proper connection to ABS hydraulic
unit/control module at terminal “E136-25”.
4) If OK, then measure voltage between con-
nector terminal “E136-25” and body ground.
Is it 10 – 14 V?Substitute a known-good
ABS hydraulic unit/con-
trol module assembly and
recheck.“WHT/BLU” circuit open
or short to ground.
