MIL Does Not Come ON with Ignition Switch ON and Engine Stop (but Engine Can Be Started)S7RS0B1104011
Wiring Diagram
Circuit Description
When the ignition switch is turned ON, ECM causes the main relay to turn ON (close the contact point). Then, ECM
being supplied with the main power, transmits indication ON si gnal of MIL to combination meter in order to turn MIL
ON. And then, combination meter turns MIL ON. When the engine starts to run and no malfunction is detected in the
system, ECM transmits MIL indication OFF signal to combination meter in order to turn MIL OFF. And then,
combination meter turns MIL OFF, but if a malfunction was or is detected, MIL remains ON even when the engine is
running.

DTC ClearanceS7RS0B4504006
WARNING!
When performing a driving test, select a safe
place where there is neither any traffic nor
any traffic accident possibility and be very
careful during testing to avoid occurrence of
an accident.

After repair or replace malfunction part(s), clear all DTCs
by performing the following procedure or using SUZUKI
scan tool.
1) Connect SUZUKI scan tool to data link connector in the same manner as when making this connection
for DTC check.
2) Turn ignition switch to ON position.
3) Erase DTC according to instructions displayed on scan tool. Refer to scan tool operator’s manual for
further derails.
NOTE
For DTC C 1021, C1022, C1025, C1026, C1031,
C1032, C1035, C1036 and C1061, confirm that
ABS warning light turns off after performing
Step 2 of “Test Driving” under “ABS Check”,
and then clear the DTCs.

4) After completing the clear ance, turn ignition switch
OFF and disconnect scan tool from data link
connector.
5) Perform “Driving Test” (S tep 2 of “ABS Check”) and
“DTC Check” and confirm that NO DTC is displayed
on scan tool.
Scan Tool DataS7RS0B4504007
The parameter data below are values measured with the

operational condition of the pump motor driver
(transistor).
RF Wheel Speed, LF Wheel Speed, RR Wheel Speed and LF Wheel Speed (km/h, MPH): Wheel speed
is an ABS control module inte rnal parameter. It is
computed by reference pulses from the wheel speed
sensor.
Brake Switch (ON, OFF): This switch signal informs
the ABS control modu le whether the brake is active
or not.

ABS Warning Lamp Does Not Come ON at Ignition Switch ONS7RS0B4604048
Wiring Diagram4
Check ESP ® control module power supply circuit
1) Turn ignition switch to OFF position.
2) Check for proper connection to ESP ® control module
connector at terminals “E85-1” and “E85-32”.
3) If OK, then turn ignition switch to ON position and measure voltage between each terminal of “E85-1”,
“E85-32” and vehicle body ground.
Are they 10 – 14 V? Go to Step 5. “WHT/BLU” and/or
“WHT/RED” circuit
open.
5 Check ESP ® control module ground circuit
1) Turn ignition switch to OFF and measure resistance between each terminal of “E85-16”, “E85-47” and vehicle
body ground.
Is resistance less than 2
Ω? Go to Step 6.
Ground circuit for ESP®
control module open or
high resistance.
6 CAN communication circuit check
1) Check CAN communication circuit between combination
meter and ESP ® control module 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 warning
lamp remains ON,
substitute a known-
good ESP
® hydraulic
unit / control module
assembly and recheck. Repair or replace.

Circuit Description
Operation (ON/OFF) of ABS warning lamp is controlled by ESP® control module through lamp driver module in
combination meter.
If antilock brake system is in good condition, ESP ® control module turns ABS warning lamp 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 lamp is
turned ON continuously by ESP ® control module. Also, it is turned ON continuously by lamp driver module when the
connector of ESP ® control module is disconnected.

DTC detecting condition Trouble area
DTC C1121:
Vehicle speed signal is 0 km/h even though engine speed
is more than 4000 rpm for more than 60 seconds
continuously (before elapse of 5 min from engine start) or
vehicle speed signal is 0 km/h even though engine speed
is more than 2500 rpm for more than 60 seconds
continuously (after elapse of 5 min for engine start).
(1 driving cycle detection logic but MIL does not light up)
DTC C1123:
Vehicle speed signal is 0 km/h with continuously more
than 3 driving cycles even though engine speed is more
than 4000 rpm for more than 30 seconds continuously
(before elapse of 5 min from engine start) or vehicle speed
signal is 0 km/h with continuously more than 3 driving
cycles even though engine speed is more than 2500 rpm
for more than 30 seconds continuously (after elapse of 5
min for engine start).
(3 driving cycle detection logic)
DTC C1124:
Vehicle speed signal is less than 5 km/h for more than 5
seconds continuously with more than specified
deceleration speed (–20 m/s
2) from over 20 km/h.
