Trunk Lid Opener Function of Keyless Start System (Sedan)

When the trunk lid request switch (1) is pushed, the keyless start control module (2) activates the trunk room antenna
(3) to send out the radio wave in the trunk room to check if the remote controller (4) is in the trunk room or not. When
the keyless start control module receives no signal from the remote controller (i.e., the remote controller does not exist
in the trunk room), it activates the trunk lid antenna (5) to send the request signal out of the compartment.
If the remote controller exists within the trunk lid opener operation area, it receives the request signal sent from the
trunk lid antenna, sends the ID code of the remote controller and the request signal to the keyless start control module
and at the same time, it makes the operation indicator light (6) of the remote controller light up. Lighting of the
operation indicator light indicates that the remote controller sent the ID code and the request signal.
The keyless start control module compares the ID code sent from the remote controller with the ID code registered in
the keyless start control module. If both ID codes match, the keyless start control module outputs the trunk lid open
request signal to BCM (7). When BCM receives such signal through CAN communication from the keyless start
control module, it activates the trunk lid opener actuator (8) to open trunk lid.
When the trunk lid is closed while the front driver side and/or front passenger side door lock is at the lock position and
all doors are closed, the keyless start control module activates the trunk room antenna to send the radio wave in the
trunk room so as to check whether the remote controller is in the trunk room or not. When the keyless start control
module receives a signal from the remote controller (i.e., the remote controller exists in the trunk room), the function
the keyless start system to prevent the remote controller from being closed in the trunk room and the keyless start
control module sends a trunk lid open request signal to open trunk lid to BCM. In this way, trunk lid is kept opened.

Furthermore, when ID codes of the remote controller and keyless start control module do not match or the remote
controller exists outside of the operation area, trunk lid is not opened even if the trunk lid request switch is operated.

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.

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.

increasing revs when changing gears

1 comments:
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.
