Check front and/or rear encoder for the following (remove
front and/or rear drive shaft):
• Encoder surface neither crack nor damaged
• No foreign material being attached
• Encoder not being eccentric
• Wheel bearing free from excessive play
Are they in good condition?
Go to Step 6.
Clean, repair or replace
wheel hub assembly.

1) Install wheel speed sensor to knuckle.
2) Tighten sensor bolt to specified torque and check that
there is no clearance between sensor and knuckle.
Is it OK?
Go to Step 7.
Replace ABS wheel
speed sensor.
7
Refer to “Front Wheel Speed Sensor On-Vehicle Inspection”
and/or “Rear Wheel Speed Sensor On-Vehicle Inspection”,
check output voltage or waveform.
Is specified voltage and/or waveform obtained?
Substitute a known-
good ABS (ESP
®)
hydraulic unit / control
module assembly and
recheck.
Replace sensor and
recheck.

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.

Was “ABS Check” performed?
Go to Step 2.
2
1) Disconnect ABS (ESP
®) hydraulic unit / control module
connector with ignition switch turned OFF.
2) Check for proper connection to ABS (ESP
®) control
module connector at terminals “E03-14”, “E03-13” and
“E03-26” (or “E53-1”, “E53-16” and “E53-47”).
3) If OK, then turn ignition switch to ON position and
measure voltage between terminals “E03-14” and “E03-
13”, “E03-26” (or “E53-1” and “E53-16”, “E53-47”).
Are voltage 9.7
±
0.3 V or more?
Go to Step 5.
Go to Step 3.
3
1) Turn ignition switch to OFF position.
2) Check for proper connection to ABS (ESP
®) 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”, “E03-26”
(or “E53-16”, “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 in related
manual”.
5
1) Measure voltage between terminals “E03-14” and “E03-
13”, “E03-26” (or “E53-1” and “E53-16”, “E53-47”) with
engine running.
Are voltage 18
±
1.0 V or less?
Poor connection of
“E03-14”, “E03-13” and/
or “E03-26” (or “E53-1”,
“E53-16” 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 in related
manual”.
