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 light will be turned off and
the ABS (ESP®) control module will return to normal operation, but the set DTC will be remain.
DTC Troubleshooting
Step
1 Was "ABS Check" performed?
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?
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
4 1) Measure voltage between positive battery terminal and
vehicle body ground with engine running.
±
Is voltage 9.7 0.3 V or more?
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?

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