Table – A “ABS” Warning Lamp Circuit Check – Lamp Does Not Come “ON” at
Ignition Switch ON
CIRCUIT DESCRIPTION
Operation (ON / OFF) of the “ABS” warning lamp is controlled by the ABS control module and ABS lamp driver
module.
If the Antilock brake system is in good condition, the ABS control module turns the “ABS” warning lamp ON at
the ignition switch ON, keeps it ON for 2 seconds only and then turns it OFF. If an abnormality in the system is
detected, the lamp is turned ON by ABS control module. Also, it is turned ON by ABS lamp driver module when
the connector of the ABS control module was disconnected.

DTC C1063 (DTC 63) – ABS Fail Safe Circuit
DESCRIPTION
The ABS control module monitors the voltage at the terminal of the solenoid circuit constantly with the ignition
switch turned ON. Also, immediately after the ignition switch is turned “ON”, perform an initial check as follows.
Switch the fail safe transistor in the order of ON → OFF → ON and check if the voltage at 6 solenoid circuit ter-
minals changes to High → Low → High. If anything faulty is found in the initial check and when the voltage at all
solenoid circuit terminals is low with the ignition switch turned ON and ABS not operated, this DTC will be set.

On-Vehicle Service
Precaution
When connectors are connected to ABS hydraulic unit / control
module assembly, do not disconnect connectors of sensors, fuse
etc. and turn ignition switch ON. Then DTC will be set in ABS con-
trol module.
ABS Hydraulic Unit Operation Check
1) Check that basic brake system other than ABS is in good
condition.
2) Check that battery voltage is 11 V or higher.
3) With ABS warning lamp, check that no abnormality is
detected in ABS. Refer to “Diagnostic Trouble Code (DTC)
Check” in this section.
4) Lift up vehicle.
5) Set transmission to neutral and release parking brake.
6) Turn each wheel gradually by hand to check if brake drag-
ging occurs. If it does, correct.
7) With diag. switch terminal (3) of monitor connector (1) con-
nected to ground terminal (2) by using service wire (4), turn
ignition switch ON and check if ABS warning lamp indicates
DTC 12.
When other DTC’s appear on display, refer to “ABS Diagnos-
tic Flow Table” in this section.
8) Turn ignition switch OFF.
9) Perform following checks with help of another person.
Brake pedal (1) should be depressed and then ignition
switch (2) turned ON by one person and wheel (3) should be
turned by another person’s hand. At this time, check that:
Operation sound of solenoid is heard and wheel turns only
about 0.5 sec (Brake force is depressurized).
Operation sound of pump motor is heard and pulsation is felt
at brake pedal.
10) If all 4-wheels cannot be checked during one ignition cycle
(OFF → ON), repeat Steps 8) and 9) till all 4 wheels are
checked.
If a faulty condition is found in Steps 9) and 10), replace
hydraulic unit.
11) Turn ignition switch OFF.
12) Remove service wire from monitor connector.

Precaution in Diagnosing Trouble
Don’t disconnect couplers from ECM, battery cable at battery, ECM ground wire harness from engine or
main fuse before confirming diagnostic information (DTC, freeze frame data, etc.) stored in ECM memory.
Such disconnection will erase memorized information in ECM memory.
Diagnostic information stored in ECM memory can be cleared as well as checked by using SUZUKI scan
tool or generic scan tool. Before using scan tool, read its Operator’s (Instruction) Manual carefully to have
good understanding as to what functions are available and how to use it.
Priorities for diagnosing troubles (Vehicle with Immobilizer indicator lamp).
If multiple diagnostic trouble codes (DTCs) are stored, proceed to the flow table of the DTC which has
detected earliest in the order and follow the instruction in that table.
If no instructions are given, troubleshoot diagnostic trouble codes according to the following priorities.
–Diagnostic trouble codes (DTCs) other than DTC P0171/P0172 (Fuel system too lean / too rich), DTC
P0300/P0301/P0302/P0303/P0304 (Misfire detected) and DTC P0400 (EGR flow malfunction)
–DTC P0171/P0172 (Fuel system too lean / too rich) and DTC P0400 (EGR flow malfunction)
–DTC P0300/P0301/P0302/P0303/P0304 (Misfire detected)
Be sure to read “Precautions for Electrical Circuit Service” in Section 0A before inspection and observe what
is written there.
ECM Replacement
When substituting a known-good ECM, check for following conditions. Neglecting this check may cause
damage to a known-good ECM.
–Resistance value of all relays, actuators is as specified respectively.
–MAP sensor and TP sensor are in good condition and none of power circuits of these sensors is shorted
to ground.AMBIENT TEMPERATURE TIME TO CUT POWER TO
ECM
Over 0 °C (32 °F) 60 sec. or longer
Under 0 °C (32 °F)Not specifiable.
Select a place with higher than
0 °C (32 °F) temperature.

4) After completing the check, turn the ignition switch OFF posi-
tion and disconnect service wire from monitor coupler.
Diagnostic trouble code (DTC) clearance
[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 ON.
3) Erase DTC and pending DTC according to instructions dis-
played on scan tool. Refer to scan tool operator’s manual for
further details.
4) After completing the clearance, turn ignition switch off and
disconnect scan tool from data link connector.
[Without Using SUZUKI Scan Tool]
1) Turn the ignition switch OFF position.
2) Disconnect battery negative cable for specified time below to
erase diagnostic trouble code stored in ECM memory and
reconnect it.
Time required to erase DTC NOTE:
If abnormality or malfunction lies in two or more areas,
malfunction indicator lamp indicates applicable codes
three times each.
And flashing of these codes is repeated as long as
diagnosis terminal is grounded and ignition switch is
held at ON position.
Take a note of diagnostic trouble code indicated first.
NOTE:
DTC and freeze frame data stored in ECM memory are
also cleared in following cases. Be careful not to clear
them before keeping their record.
When power to ECM is cut off (by disconnecting bat-
tery cable, removing fuse or disconnecting ECM con-
nectors)
When the same malfunction (DTC) is not detected
again during 40 engine warm-up cycles.
Ambient temperature Time to cut power to ECM
Over 0 °C (32 °F) 30 sec. or longer
Under 0 °C (32 °F)Not specifiable.
Select a place with higher than
0 °C (32 °F) temperature.
