Driver / passenger curtain-air bag circuit check
1) Disconnect special tools from applicable side curtain-air
bag connector.
2) With ignition switch turned OFF, disconnect SDM
connector "L04".
3) Check for proper connection to SDM connector at
terminal "L04-19" and "L04-20" (for DTC B1362) or
terminal "L04-21" and "L04-22" (for DTC B1366).
4) If OK, release shorting bar in SDM connector inserting
release tool (1) included in special tool (A).
Special tool
(A): 09932–76010
5) Measure resistance between "L04-19" and "L04-20"
terminals (for DTC B1362) and between "L04-21" and
"L04-22" terminals (for DTC B1366).
"L04-19"
"L04-20" "L04-21"
Is each measured resistance infinity?

Floor harness circuit check (hatchback model)
1) With ignition switch turned OFF, remove rear inner trim
of right side and disconnect "L395" connector.
2) Check for proper connection to applicable side curtain-
air bag at terminal in "L395" connector.
3) If OK, release shorting bar in SDM connector inserting
release tool (1) included in special tool (A).
Special tool
(A): 09932–76010
4) Measure resistance between "L04-19" and "L04-20"
terminals (for DTC B1362) and between "L04-21" and
"L04-22" terminals (for DTC B1366).
"L395"
Is each measured resistance infinity?
NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components, ensure all components are properly mounted.
• Clear DTCs referring to "DTC Clearance", if any.
• Repeat "Air Bag Diagnostic System Check" to confirm that the trouble has been corrected.

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.
