Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the voltage at the terminal of each sensor while the ignition swit ch is ON. When the
voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor signal is inputted at
running, an applicable DTC will be set.
NOTE
When the vehicle was operated in any of the following ways, one of these DTCs may be set even when
the sensor is in good condition. If such possibility is suspected, clear DTC once referring to “DTC
Clearance” and then performing the driving test as described in Step 2 of “ABS Check”, check whether
or not any abnormality exists.
• The vehicle was driven with parking brake pulled.
• Wheel spin occurred while driving.
• Wheel(s) was turned while the vehicle was jacked up.
• The vehicle was stuck.

Check
S7RS0B4604047
NOTE
Perform this check on a level place.

1) Turn ignition switch ON with parking brake applied.
2) Check that EBD warning lamp (brake warning lamp)
(1) is turned ON.
3) Release parking brake with ignition switch ON and check that EBD warning lamp (brake warning lamp)
goes off.
If it doesn't go off, go to “EBD Warning Lamp (Brake
Warning Lamp) Comes ON Steady”.
DTC CheckS7RS0B4604004
1) Turn ignition switch to OFF position.
2) Connect SUZUKI scan tool to data link connector (1).
Special tool
(A): SUZUKI scan tool
3) Turn ignition switch to ON position.
4) Read DTC according to instructions displayed on
SUZUKI scan tool and print it or write it down. Refer
to SUZUKI scan tool operator’s manual for further
details.
NOTE
If SUZUKI scan tool can not communicate
ESP® control module, perform “Serial Data
Link Circuit Check”.

5) After completing the check, turn ignition switch off and disconnect SUZUKI scan tool from DLC.

3) If connections are OK, check stop lamp switch circuit for
the following.
• Resistance of “GRN/WHT” wire terminal of stop lamp switch between stop lamp switch connector and ECM
connector is less than 1 Ω (continuity check)
• Resistance between “GRN/WHT” wire terminal of stop lamp switch connector and vehicle body ground is
infinity (ground short check)

ignition switch tuned ON (power short check)
Are they in good condition? Substitute a known-
good ECM and recheck.
If DTC C1016 is still
detected, substitute a
known-good ESP
®
hydraulic unit / control
module assembly and
recheck. Repair or replace
defective wire.
