Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

2

1) Turn ignition switch to OFF position.
2) Disconnect ABS (ESP

®) hydraulic unit / control module

connector.

3) Check for proper connection to ABS (ESP

®) hydraulic

unit / control module connector at terminal “E03-14” (or
“E53-1”).

4) If OK, then measure voltage between terminal “E03-14”

(or “E53-1”) of module connector and “E03-26” (or “E53-
47”).

Is it 10 – 14 V?

Substitute a known-
good ABS (ESP

®)

hydraulic unit / control
module assembly and
recheck.

DTC C1057: ABS (EPS

®) Control Module Power Supply Circuit Failure

S5JB0B4504016

Wiring Diagram

DTC Detecting Condition
The ABS (ESP

®) control module monitors the power source voltage at terminal “E03-14” (or “E53-1”). 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 voltage becomes normal, the ABS warning lamp will be turned off and
the ABS (ESP

®) control module will return to normal operation, but the set DTC will be remain.

1

Was “ABS Check” performed?

Go to Step 2.

Go to “ABS Check”.

2

1) Disconnect ABS (ESP

®) hydraulic unit / control module

connector with ignition switch turned OFF.

2) Check for proper connection to ABS hydraulic unit /

control module connector at terminals “E03-14” and
“E03-13” (or “E53-1” and “E53-47”).

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

measure voltage between terminals “E03-14” and “E03-
13” (or “E53-1” and “E53-47”).

Is voltage 9.7

±

0.3 V or more?

Go to Step 5.

Go to Step 3.

3

1) Turn ignition switch to OFF.
2) Check for proper connection to ABS (ESP

®) hydraulic

unit / control module connector at terminals “E03-13”
and “E03-26” (or “E53-16” and “E53-47”).

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

resistance between each terminal of “E03-13” and “E03-
26” (or “E53-16” and “E53-47”) and vehicle body ground.

Is resistance less than 2

Ω

?

Go to Step 4.

“BLK” wire circuit in
open or high resistance.

4

1) Measure voltage between positive battery terminal and

vehicle body ground with engine running.

Is voltage 9.7

±

0.3 V or more?

Imperfect short between
“WHT/RED” wire circuit
and body ground.

Check charging system
referring to “Generator
Test (Undercharged
Battery Check) in
Section 1J”.

5

1) Measure voltage between terminals “E03-14” and “E03-

13” (or “E53-1” and “E53-47”) with engine running.

Is voltage 18

±

1.0 V or less?

Poor connection of
“E03-14” and/or “E03-
13” (or “E53-1” and/or
“E53-47”) terminals. If
the terminals are in
good condition,
substitute a known-
good ABS (ESP

®)

hydraulic unit / control
module and recheck.

Check charging system
referring to “Generator
Test (Overcharged
Battery Check) in
Section 1J”.
