ESP® Hydraulic Unit Operation Check
1) Check that basic brake system other than ESP® is
in good condition.
2) Check that battery voltage is 11 V or higher.
3) Lift up vehicle.
4) Set transmission to neutral and release parking
brake.
5) Turn each wheel gradually by hand to check if
braked ragging occurs. If it does, correct.
6) Connect SUZUKI scan tool to data link connector
(DLC) (1) with ignition switch OFF.

7) Turn ignition switch to ON position and select menu
press / depress in "HYDRAULIC CONTROL TEST"
under "miscellaneous test" ("MISC. TEST") mode of
SUZUKI scan tool.
Refer to SUZUKI scan tool operator's manual for
further details.
8) Perform the following checks with help of another
person.
• Depressurization check
Step on brake pedal (1) and then select testing
wheel by SUZUKI scan tool and the wheel (2)
should be turned by another person's hand. At this
time, check whether the wheel rotates freely due
to brake depressurization.
• Pressurization check
Step off brake pedal (1) and then select testing
wheel by SUZUKI scan tool and the wheel (2)
should be turned by another person's hand. At this
time, check whether the wheel locks due to brake
pressurization.
NOTE
Pressurization / Depressurization by SUZUKI
scan tool is available for 0.5 second.

Using SUZUKI Scan Tool
1) Set steering wheel in straight-ahead position.
2) Connect SUZUKI scan tool to data link connector
faulty condition is found, replace hydraulic unit /
control module assembly.
OFF position and disconnect SUZUKI scan tool from
DLC.
CAUTION
!
If any DTC other than C1075 is detected,
sensor calibration can not be completed.
Repair the detected DTC first.
NOTE
Steering angle sensor calibration is needed
when battery, "DOME" fuse or the steering
angle sensor is removed.
This sensor calibration can be done with/
without SUZUKI scan tool.

Questions and answers
Adjust throttle motor
The idle speed on a Suzuki SX4 should be controlled by the Idle Air Control Valve (IACV) rather than adjusting the idle screw on the throttle body, as the screw is factory set. Before using compressed air in the idle-air-bypass passages, the IACV should be removed to prevent damage to its delicate mechanism. If there is an issue with idle speed, checking the IACV function and referring to the SX4 service manual is recommended.

I have an issue of crank but not starting When I scan it brought this codeU0100 Which means no communication thou crank sensor wire was cut off but it was fix back What could be wrong and what could be the solution,
My heater stopped working the blower **** is good, control unit ?
Possible issues with the heater in a Suzuki SX4 if the blower is working but the heater is not include:
1. Incorrect Temperature Output
- Temperature control cable broken or bent (non-A/C and manual A/C) → Check the temperature control cable.
- Temperature selector faulty (non-A/C and manual A/C) → Check the temperature selector.
- Incorrect installation of the temperature control cable (non-A/C and manual A/C) → Check and adjust the position as necessary.
- Temperature control door assembly broken → Repair the temperature control door assembly.
- Air ducts clogged → Repair air ducts.
- Heater core leaked or clogged → Replace the heater core.
- Heater hoses leaked or clogged → Replace heater hoses.
- Thermostat faulty → Check the thermostat.
- Temperature control actuator faulty (auto A/C) → Check the temperature control actuator.
- HVAC control module faulty (auto A/C) → Check the HVAC control module.
- Wiring or grounding faulty (auto A/C) → Repair as necessary.
2. Other Possible Causes
- Air flow control cable broken or bent → Check the air flow control cable.
Checking and addressing these components should help identify and resolve the heater issue.

increasing revs when changing gears
The Suzuki SX4 may have increasing revs when changing gears due to its drive-by-wire system and the difference in final drive ratios between the manual (4.41) and automatic (2.81) transmissions. This difference causes high cruising RPMs in the manual version and sluggishness in the automatic. Additionally, if the revs climb while going uphill, it may be due to the transmission downshifting or kicking out of overdrive. Other possible causes include low transmission fluid, abuse, or a faulty transmission design.
