ABS: 4E-14
ABS Warning Light Comes ON Steady
S7RS0B4504009
Wiring Diagram
Refer to “ABS Warning Light Does Not Come ON at Ignition Switch ON”.
Circuit Description
Operation (ON/OFF) of ABS warning light is controlled by ABS control module through lamp driver module in
combination meter.
If the Antilock brake system is in good condition, ABS control module turns ABS warning light 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 control module. Also, it is turned ON continuously by lamp 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 with ignition switch turned
OFF.
2) Check for proper connection to “RED/BLK” and “BLK/
ORN” wire of combination meter connector.
3) If OK, turn ON ignition switch and measure voltage at
“PPL/RED” wire of combination 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 Yes No
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
open.
