A/T Fluid Level Check
S7RW0A5106001
CAUTION
!
Do not use any fluid other than the specified
ATF. Use of any fluid other than the specified
ATF may cause juddering or some other
faulty condition to occur.
Level Check at Normal Operating (Hot) Temperature
– Hot Check
1) Stop vehicle and place it level.
2) Apply parking brake and place chocks against
wheels.
3) With select lever at "P" position, start engine.
4) Warm up engine till fluid temperature reaches
normal operating temperature (70 – 80 °C / 158 –
I5RW0C510072-01
176 °F). As a guide to check fluid temperature, warm
up engine to normal operating.
5) Keep engine idling and shift select lever slowly to "L"
and back to "P" position.
6) With engine idling, pull out fluid level gauge, wipe it
off with a clean cloth and put it back into place.

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.

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.

دلایل بالا رفتن مصرف بنزین در مدل اتومات
we bought the car & had no issues besides the filler neck. we changed it & then later on down the road we jumped another car with the suzuki sx4 & after doing it blew the alternator, got new alternator & now if we don't turn headlights on BEFORE you start the car you can hear some pump in the trunk area going on & off. Or you can pull up on the emergency brake one click & it will stop. if you turn off the headlights after it's running the noise will come back. it did NOT do this until we jumped another vehicle, that is what blew the alternator. we have a brand new one in the car now. any ideas of why it's doing this? it seems electrical but we don't know where to begin.
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,
A Suzuki SX4 that cranks but does not start with a U0100 code (Lost Communication with ECM/PCM) after the crank sensor wire was repaired could have the following issues:
1. Faulty Engine Swap: The engine may not be compatible or not properly installed, as noted in the context that the problem started after an engine replacement.
2. Crankshaft Sensor Issues: Even after repairing the crank sensor wire, the sensor itself could be faulty or not sending a proper signal.
3. ECU Communication Problem (U0100): This indicates a loss of communication with the ECU, possibly due to wiring faults, poor ground connections, or a damaged ECU.
4. Starter Motor Issues: Although the engine cranks, if the starter motor is weak or has voltage issues (as noted with 11.5V), it may not spin the engine fast enough for it to start.
In summary, the likely causes are improper engine installation, crank sensor signal issues, ECU communication failure, or weak starter motor performance.

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.
