warning SUZUKI SX4 2006 1.G Service Owners Manual

Downloaded from www.Manualslib.com manuals search engine ABS: 4E-14
Circuit Description
ABS control module transmits indication ON signal of ABS warning light to combination meter in order to turn ABS
warning light ON. And then, combination meter turns ABS warning light ON.
If the ABS is in good condition, ABS control module transmits indication ON signal to combination meter in order to
turn ABS warning light ON at the ignition switch ON, keeps it ON for 2 seconds and then turns it OFF. If an abnormality
in the system is detected, ABS warning light is turned ON continuously by ABS control module. Also, it is turned ON
continuously by light driver module when ABS control module connector is disconnected.

EBD Warning Light (Brake Warning Light) Comes ON SteadyS6RW0D4504010
Wiring Diagram
Referring to “Wiring Diagram” under “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
EBD warning lamp (brake warning lamp) is controlled by ABS control module and BCM through lamp driver module in
combination meter.
If EBD system is in good condition, ABS control module turns EBD warning lamp ON at the ignition switch ON, keeps
it ON for 2 seconds and then turns it OFF.
EBD warning lamp is turned ON continuously at the following conditions.
• EBD system is an abnormality
• Connector of ABS control module is disconnected
• Parking brake switch is ON
• Brake fluid level is lower than minimum level
The information of parking brake switch and brake fluid level are transmitted from BCM to lamp driver module in
combination meter through CAN communication line.
Troubleshooting

On-Board Diagnostic System DescriptionS6RW0D5101005
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
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
