DTC Detecting Condition
The ABS (ESP®) control module monitors the output from the valve.
When the output of each valve exceeds the specified value compared with the signal sent from ABS (ESP®) control
module, this DTC is set.
DTC Troubleshooting
Step
1 Was "ABS Check" performed?
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?
