4E-14 ABS: 

Troubleshooting

Step

Action

Yes

No

1

1) Turn ignition switch to ON position.

Do other warning lamps come ON?

Go to Step 2.

Go to Step 3.

2

1) Connect scan tool to DLC with ignition switch turned 

OFF.

2)  Turn ignition switch to ON position and check DTC.

Is there DTC U1073?

Go to “DTC U1073: 
Control Module 
Communication Bus 
Off”
.

Substitute a known-
good combination meter 
and recheck. If ABS 
warning lamp remains 
OFF, substitute a 
known-good ABS 
(ESP

®) hydraulic unit / 

control module 
assembly and recheck.

3

Is Circuit fuse for combination meter in good condition?

Go to Step 4.

Replace fuse and check 
for short circuit to 
ground.

4

Check CAN communication circuit between combination 
meter and ABS (ESP

®) 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 “PPL/RED” and “BLK” 

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” wire of combination 

meter connector and vehicle body ground.

Is resistance less than 2 

?

Replace combination 
meter.

“BLK” circuit open or 
high resistance.

ABS: 4E-15

ABS Warning Lamp Comes ON Steady

S5JB0E4504009

Wiring Diagram
Refer to “ABS Warning Lamp Does Not Come ON at Ignition Switch ON”.

Circuit Description
Operation (ON/OFF) of ABS warning lamp is controlled by ABS (ESP

®) control module through lamp driver module in 

combination meter.
If the Antilock brake system is in good condition, ABS (ESP

®) control module turns ABS warning lamp 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 lamp is turned ON continuously by ABS (ESP

®) control module. Also, it is turned ON continuously by lamp 

driver module when the connector of ABS (ESP

®) control module is disconnected.

Troubleshooting

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 (ESP

®) control module connector.

3) Check for proper connection to ABS (ESP

®) control 

module connector at terminals “E03-7”, “E03-13” and 
“E03-26” (or “E53-16”, “E53-35” and “E53-47”).

4) If OK then turn ignition switch to ON position and 

measure voltage between terminal “E03-7” (or “E53-35”) 
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 (ESP

®) control 

module connector at terminals “E03-1” and “E03-14” (or 
“E53-1” and “E53-32”).

3) If OK then turn ignition switch to ON position and 

measure voltage between each terminal of “E03-1”, 
“E03-14” (or “E53-1”, “E53-32”) and vehicle body 
ground.

Are they 10 – 14 V?

Go to Step 5.

“WHT/RED” and/or 
“WHT/BLU” circuit 
open.

5

1) Turn ignition switch to OFF and measure resistance 

between each terminal of “E03-13”, “E03-26” (or “E-53-
1”, “E53-32”) and vehicle body ground.

Is resistance less than 2 

?

Go to Step 6.

Ground circuit for ABS 
(ESP

®) hydraulic unit / 

control module open or 
high resistance.

6

Check CAN communication circuit between combination 
meter and ABS (ESP

®) control module referring to “DTC 

U1073: Control Module Communication Bus Off”.

Is CAN communication circuit in good condition?

Substitute a known-
good combination meter 
and recheck. If ABS 
warning lamp remains 
ON, substitute a known-
good ABS (ESP

®) 

hydraulic unit / control 
module assembly and 
recheck.

Repair or replace.

4E-16 ABS: 

EBD Warning Lamp (Brake Warning Lamp) Comes ON Steady

S5JB0E4504011

Wiring Diagram

Circuit Description
EBD warning lamp (brake warning lamp) is controlled by parking brake switch, brake fluid level switch and ABS 
(ESP

®) control module assembly through lamp driver module in combination meter.

EBD warning lamp turns ON when parking brake switch is ON and/or brake fluid level is lower than minimum level.
The information of parking brake switch and brake fluid level are transmitted from BCM to lamp driver module in 
combination meter through CAN communication line.
