Downloaded from www.Manualslib.com manuals search engine Electronic Stability Program: 4F-25
Circuit Description
EBD warning lamp (brake warning lamp) is controlled by ESP® control module and BCM through lamp driver module
in combination meter.
If EBD system is in good condition, ESP ® 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 cont inuously at the following conditions.
• EBD system is an abnormality
• Connector of ESP ® 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 leve l are transmitted from BCM to lamp driver module in
combination meter through CAN communication line.
Troubleshooting
Step Action Yes No 1 Check parking brake and brake fluid level
1) Make sure that:
• Parking brake is completely released.
• Brake fluid level is upper than the minimum level.
Are the check results OK? Go to Step 2. Release parking brake
completely and/or
replenish brake fluid.
2 Check ABS warning lamp
1) Turn ignition switch to ON position.
Does ABS warning lamp come on steady? Perform “ABS Warning
Lamp Does Not Come
ON at Ignition Switch
ON” previously outlined.Go to Step 3.
3 Check parking brake switch circuit and brake fluid level
switch circuit
1) Release parking brake completely, and replenish brake
fluid.
2) Disconnect BCM connectors with ignition switch turned OFF.
3) Measure resistance between each terminal of “L01-6”, “E46-5” and vehicle body ground.
Are resistance
∞ Ω? Go to Step 4. Check each applicable
circuit for short to
vehicle body ground. If
OK, then check parking
brake switch and/or
brake fluid level switch.
4 CAN communication circuit check
1) CAN communication circuit between combination meter,
ABS (ESP® ) control module and BCM referring to “DTC
U1073: Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Substitute a known-
good combination meter
and recheck. If EBD
warning lamp remains
ON, substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Repair or replace.

3) Turn ignition switch to ON position and confirm that
only any of DTC(s) C1075, C1076 and/or C1077 is
detected. If any other DTC are detected, repair the
detected DTC.
4) Park and level the vehicle with parking brake, stop engine with ignition switch ON, set steering in
straight and without step ping on the brake pedal.
NOTE
Hold the above condition in Step 4) to
calibrate sensor correctly until sensor
calibration is completed.

5) Select menu “SENSOR CALIBRATION” under
“MISC. TEST” mode of SUZUKI scan tool and
calibrate sensor. Refer to scan tool operator's
manual for further derails.
6) After completing the calibra tion, turn ignition switch
