4A-6 Brake Control System and Diagnosis:

Excessive Pedal Travel Inspection

1) Start engine.
2) Depress brake pedal a few times.
3) With brake pedal depressed with approximately 300
N (30 kg, 66 lbs) load, measure brake pedal to wall
(dash panel silencer) clearance "a". If clearance is
out of specification, possible causes are as follows.
If clearance "a" is less than specification, the most
possible cause is that air is in lines or brake fluid
leakage.
Should clearance "a" remain less than specification
even after bleeding of system, other possible but
infrequent cause is malfunction of booster push rod
length out of adjustment.
• Bleed brake system. Refer to "Air Bleeding of
Brake System".

When pedal is depressed at 300 N (30 kg, 66 lbs)
"a": Over 40 mm (1.57 in.)

Brake Fluid Level Inspection

S7RW0A4106004
CAUTION
!
Do not use shock absorber fluid or any other
fluid which contains mineral oil. Do not use a
container which has been used for mineral oil
or a container which is wet from water.
Mineral oil will cause swelling and distortion
of rubber parts in hydraulic brake system and
water mixed into brake fluid will lower fluid
boiling point. Keep all fluid containers
capped to prevent contamination.
NOTE
Be sure to use particular brake fluid either as
indicated on reservoir cap of that vehicle or
recommended in owner's manual which
comes along with that vehicle. Use of any
other fluid is strictly prohibited.
Fluid level should be between MIN and MAX
lines marked on reservoir.
When brake warning light lights sometimes
during driving, replenish fluid to MAX level.
When fluid decreases quickly, inspect brake
system for leakage. Correct leaky points and
then refill to specified level.
1) Check master cylinder, reservoir and reservoir hose
(if equipped) for crack, damage and brake fluid
I6RW0C410006-01
leakage. If any faulty condition exists, correct or
replace.
2) Check that brake fluid level is between MAX (1) and
MIN marks (2) on reservoir.

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.

increasing revs when changing gears

Mr. Anderson

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.

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.
