Repair Instructions
ABS Hydraulic Unit Operation Check
S6RW0C4506001
1) Check that basic brake system other than ABS is in
good condition.
2) Check that battery voltage is 11 V or more.
3) Hoist vehicle.
4) Set transmission to neutral (P range for A/T) and
release parking brake.
5) Turn each wheel gradually by hand to check if brake
dragging occurs. If it does, correct.
6) Connect SUZUKI scan tool to data link connector
(DLC) (1) with ignition switch OFF.
Special tool
(A): SUZUKI scan tool
Step Action Yes No
1 Check fuse
Are main fuses and circuit fuses for ABS in good condition?
Go to Step 2. Replace fuse and check
for short circuit to
ground.
2 Check ABS control module power supply circuit
1) Turn ignition switch to OFF position.
2) Disconnect ABS control module connector.
3) Check for proper connection to ABS control module
connector at terminals “E08-9”, “E08-23”, “E08-24”, and
“E08-25”.
4) If OK, then turn ignition switch to ON position and
measure voltage between terminal “E08-9” and vehicle
body ground.
Is it 10 – 14 V?
Go to Step 3. “GRN/ORN” circuit
open.
3 Pump motor and solenoid valve power supply circuit
1) Turn ignition switch to OFF position.
2) Measure voltage between each terminal of “E08-24”,
“E08-25” and vehicle body ground.
Are they 10 – 14 V?
Go to Step 4. “WHT/BLU” and/or
“WHT/RED” circuit
open.
4 Check ABS hydraulic unit / control module assembly
ground circuit
1) Measure resistance between terminal “E08-23” and
vehicle body ground.
Is resistance less than 2
Ω
?
ABS hydraulic unit /
control module
assembly power and
ground circuits are in
good condition. “BLK” circuit open or
high resistance.
