ABS Warning Light Comes ON SteadyS6RW0D4504009
Wiring Diagram
Refer to “Warning Diagram” under “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
Refer to “Circuit Description” under “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Troubleshooting 3Combination meter power source circuit check
1) Remove combination meter with ignition switch turned
OFF.
2) Check for proper connection to “RED/BLK” and “BLK”
wire of combination meter connector.
3) If OK then turn ON ignition switch and measure voltage
at “RED/BLK” wire of combination meter connector and
vehicle body ground.
Is it 10 - 14 V?Go to Step 4. Repair power source
circuit for combination
meter.
4Combination meter ground circuit check
1) Measure resistance between “BLK” wire of combination
meter connector and vehicle body ground.
Is resistance less than 2
Ω?Substitute a known-
good combination meter
and recheck.“BLK” circuit open or
high resistance. Step Action Yes No
Step Action Yes No
1DTC check
1) Perform diagnostic trouble code check.
Is there any DTC(s)?Go to Step 7 of “ABS
Check”.Go to Step 2.
2ABS hydraulic unit / control module assembly power
and ground circuit check
1) Check that ABS hydraulic unit / control module assembly
power supply circuit and ground circuit is in good
condition referring to “ABS Hydraulic Unit / Control
Module Assembly Power and Ground Circuit Check”.
Are check results OK?Go to Step 3. Repair ABS hydraulic
unit / control module
assembly power or
ground circuit.
3CAN communication line circuit check
1) Turn ignition switch to OFF position.
2) Disconnect connectors of all control modules
communicating by means of CAN.
3) Check for proper connection to CAN communication line
wire.
4) If OK then check CAN communication line circuit
between control modules for open, short and high
resistance.
Is each CAN communication line circuit in good condition?Substitute a known-
good combination meter
and recheck. If warning
light remains ON,
substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck.Repair circuit and
recheck.
