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
Action YesNo
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.
3 1) Turn ignition switch to OFF.
2) Disconnect ABS control module connector.
3) Check for proper connection to ABS control module connector at terminals “E03-7”, “E03-13” and “E03-26”.
4) If OK then turn ignition switch to ON position and measure voltage between terminal “E03-7” and vehicle
body ground.
Is it 10 – 14 V? Go to Step 4.
“GRN/ORN” circuit
open.
4 1) Turn ignition switch to OFF position. 2) Check for proper connection to ABS control module connector at terminals “E03-1” and “E03-14”.
3) If OK then turn ignition switch to ON position and measure voltage between each terminal of “E03-1”,
“E03-14” and vehicle body ground.
Are they 10 – 14 V? Go to Step 5.
“WHT/RED” and/or
“WHT/BLU” circuit

DTC C1057: Power Source CircuitS7RS0B4504014
Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the power source voltage at terminal “E03-14”. When the power source voltage
becomes extremely high or low while vehicle is running at more than 20 km/h (13 MPH), this DTC will be set. As soon
as the power source volta ge becomes normal, the ABS warning light will be turned off and the ABS control module will
return to normal operation, bu t the set DTC will be remain.

DTC C1061: ABS Pump Motor and/or Motor Driver CircuitS7RS0B4504015
Wiring Diagram
DTC Detecting Condition
The ABS control module monitors the voltage at monitor terminal of pump motor circuit constantly with the ignition
switch turned ON. It sets this DTC when the voltage at the monitor terminal does not become high / low according to
ON/OFF commands to the motor driver (transistor) of the module (does not follow these commands).
DTC Troubleshooting 5 1) Measure voltage between terminals “E03-14” and “E03-
13” with engine running.
Is voltage 18
± 1.0 V or less? Poor connection of
“E03-14” and/or “E03-
13” terminals. If the
terminals are in good
condition, substitute a
known-good ABS
hydraulic unit / control
module and recheck.Check charging system

DTC C1063: Solenoid Valve Power Supply Driver CircuitS7RS0B4504016
Wiring Diagram
DTC Detecting Condition
ABS control module monitors the voltage at the terminal of solenoid circuit constantly with ignition switch turned ON.
Also, immediately after ignition switch is turned ON, perform initial check as follows.
Switch solenoid valve power supply driv er (transistor) in the order of OFF → ON and check if voltage changes to Low
→ High. If anything faulty is found in the initial check and when the voltage is low with ignition switch turned ON, this
DTC will be set.
