Step Action Yes No
1 Was “ABS Check” performed? Go to Step 2. Go to “ABS Check: ”.
2 1) Turn ignition switch to OFF position.
2) Disconnect ABS (ESP®) control module connector.
3) Check for proper connection to ABS (ESP®) control
module connector at terminal “E03-14”.
4) If OK, then measure voltage between terminal “E03-14”
(or “E53-1”) of module connector and “E03-13”, “E03-26”
(or “E53-16”, “E53-47”).
Are they 10 – 14 V?
Substitute a known-
good ABS (ESP®)
hydraulic unit /control
module assembly and
recheck.
