Scan Tool Data Definitions
Accel pedal Pos (Accelerator pedal position) (%)
Accelerator pedal opening ratio detected by signal on
CAN communication line fed from ECM.
Engine Speed (RPM)
This parameter indicates engine revolution calculated by
4WD control module.
4WD mode (2WD / AUTO / LOCK / ABS mode / Yaw
cont / ESP® req)
This parameter indicates 4WD mode according to 2WD/
4WD switch signal status detected by 4WD control
module.
4WD current (A)
This parameter indicates input current of coupling
assembly.
Battery voltage (V)
This parameter indicates battery voltage detected by
4WD control module.

Coupling temp (°C, °F)
Coupling temperature detected by coupling air
temperature sensor installed in coupling assembly.
Wheel speed (F), Wheel speed (R) (km/h, mph)
Wheel speed is an ABS / ESP® control module internal
parameter. It is computed by reference pulses from the
wheel speed sensor.
F-R Wheel speed diff (Front-rear wheel speed
differential) (rpm)
This parameter indicates rotation difference between
front wheel and rear wheel detected by 4WD control
module.
4WD duty (%)
This parameter indicates operation rate of coupling
assembly.

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.

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.
