ABS Warning Light Comes ON SteadyS7RS0B4504009
Wiring Diagram
Refer to “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
Operation (ON/OFF) of ABS wa rning light is controlled by ABS contro l module through lamp driver module in
combination meter.
If the Antilock brake system is in good condition, ABS control module turns ABS warning lig ht 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 light is
turned ON continuously by ABS c ontrol module. Also, it is turned ON continuously by la mp driver module when the
connector of ABS control module is disconnected.
Troubleshooting 4 Check CAN communication circuit between combination
meter and ABS control module referring to “DTC U1073:
Control Module Communication Bus Off”.
Is CAN communication circuit in good condition? Go to Step 5.
Repair or replace.
5 1) Remove combination meter wit h ignition switch turned
OFF.
2) Check for proper connection to “RED/BLK” and “BLK/ ORN” wire of combinat ion meter connector.
3) If OK, turn ON ignition switch and measure voltage at “PPL/RED” wire of combi nation meter connector and
vehicle body ground.
Is it 10 – 14 V? Go to Step 6.
Repair power supply
circuit for combination
meter.
6 1) Measure resistance between “BLK/ORN” wire of combination meter connector and vehicle body ground.
Is resistance less than 2
Ω? Replace combination
meter.
“BLK/ORN” circuit open
or high resistance.
Step Action Yes No
Step

1 1) Perform diagnostic trouble code check.
Is there any DTC(s)? Go to applicable DTC
diag. flow.
Go to Step 2.
2 Are main fuses for ABS pump motor and ABS solenoid in
good condition? Go to Step 3.
Replace fuse and check
circuit for short to
ground.

DTC C1021, C1022 / C1025, C1026 / C1031, C1032 / C1035, C1036: Right-Front / Left-Front / Right-
Rear / Left-Rear Wheel Speed Sensor Circuit or Sensor Ring
S7RS0B4504012
Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the voltage at the terminal of each sensor while the ignition swit ch is ON. When the
voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor signal is inputted at
running, an applicable DTC will be set.
NOTE
When the vehicle was operated in any of the following ways, one of these DTCs may be set even when
the sensor is in good condition. If such possibility is suspected, clear DTC once referring to “DTC
Clearance” and then performing the driving test as described in Step 2 of “ABS Check”, check whether
or not any abnormality exists.
• The vehicle was driven with parking brake pulled.
• Wheel spin occurred while driving.
• Wheel(s) was turned while the vehicle was jacked up.
• The vehicle was stuck.
