Temperature Control Actuator and Its Circuit
Inspection
1) Remove temperature control actuator from HVAC
unit referring to "Temperature Control Actuator
Removal and Installation: Automatic Type".
2) Connect connector to temperature control actuator.
3) Set temperature selector to "MAX COOL" position
with ignition switch turned ON.
4) Connect voltage meter between terminal "2" and
body ground.
5) Turn temperature selector to "MAX HOT" position.
6) Measure output voltage variation while temperature
control actuator is operated from "MAX COOL"
position (B) to "MAX HOT" position (A) as following
specification.
If measure voltage is out of specification or does not
vary linearly as the shown in graph, check related
wire circuit and HVAC control module. If wire circuits
and HVAC control module are OK, go to next step.

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,
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.
