A/T Diagnosis General Description
This vehicle is equipped with an electronic transaxle control system, which controls the automatic shift up and shift
down timing, TCC operation, etc. suitably to vehicle driving conditions.
TCM has an On-Board Diagnosis System which detects a malfunction in this system.
When diagnosing a trouble in transaxle including this system, be sure to have full understanding of the outline of "On-
Board Diagnostic System Description" and each item in "Precautions in Diagnosing Trouble" and execute diagnosis
according to "A/T System Check" to obtain correct result smoothly.
NOTE
There are two type of On-Board Diagnostic System, Euro OBD system and non-Euro-OBD system
depending on the vehicle specification. For identification, refer to "Precaution on On-Board Diagnostic
(OBD) System in Section 1A".
On-Board Diagnostic System Description
NOTE
There are two types of OBD system
depending on the vehicle specification. For
identification, refer to "Precaution on On-
Board Diagnostic (OBD) System in Section
1A".
For automatic transaxle control system, TCM has the
following functions.
• For Euro OBD model, when the ignition switch is
turned ON with the engine at a stop, MIL (1) turns ON
to check the bulb of the MIL.
• For Euro OBD model, when TCM detects a
malfunction in A/T control system TCM desires turning
on MIL and stores malfunction DTC in TCM memory.
(If it detects that continuously 3 driving cycles are
normal after detecting a malfunction, however, it
makes MIL turn OFF although DTC stored in its
memory will remain.)
• For Euro OBD model, it is possible to communicate
with TCM through data link connector (DLC) (2) by
using not only SUZUKI scan tool (3) but also CAN
communication OBD generic scan tool. (Diagnostic
information can be checked and erased by using scan
tool.)
• For non-Euro-OBD model, when ignition switch is
turned ON and no malfunction in A/T control system is
detected, transmission warning light (4) lights for
about 2 seconds after ignition switch is turned ON and
then goes OFF for bulb check.
• For non-Euro-OBD model, when TCM detects a
S7RW0A5101005
malfunction in A/T control system, it indicates
transmission warning light (4) and stores malfunction
DTC in its memory.
• For information about the following items, refer to "On-
Board Diagnostic System Description in Section 1A".
– Warm-up cycle
– Driving cycle
– 2 driving cycle detection logic
– Pending DTC
– Freeze frame date

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
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.
