4E-13 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 OFF 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
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 hydraulic unit / 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

Ω

?

Replace combination
meter.

“BLK” circuit open or
high resistance.

ABS Warning Lamp Comes ON Steady

S5JB0A4504009

Wiring Diagram

Circuit Description
Operation (ON/OFF) of ABS warning lamp 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 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 control module. Also, it is turned ON continuously by lamp driver module when
the connector of ABS control module is disconnected.

Troubleshooting

Step

Action

Yes

No

1

1) Perform diagnostic trouble code check.

Is there any DTC(s)?

Go to Step 7 of “ABS
Check”.

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 hydraulic unit / control module

connector.

3) Check for proper connection to ABS hydraulic unit /

control module connector at terminals “E03-7”, “E03-13”
and “E03-17”.

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 hydraulic unit /

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.

5

1) Turn ignition switch to OFF and measure resistance

between each terminal of “E03-13”, “E03-26” and vehicle
body ground.

Is resistance less than 2

Ω

?

Go to Step 6.

Ground circuit for ABS
hydraulic unit / control
module open or high
resistance.

6

Check CAN communication circuit between combination
meter and ABS hydraulic unit / 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 hydraulic unit
/ control module
assembly and recheck.

Repair or replace.
