Solenoid valve driver 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 Action 1 Was "ABS Check" performed?2 1) Turn ignition switch to OFF position. 2) Disconnect ABS (ESP®) control module connector. [. . . ] No Check power and ground circuit of disconnected control module and recheck. If circuit is OK, substitute a known-good disconnected control module and recheck.
