Abs Test: Notes

Turn ignition off. Unplug ECU connector. Connect ABS Tester (Fast Check) to ECU connector. Turn ignition on. If ABS tester power light does not come on, check battery and fuse. Check for continuity in circuit between cut-out relay and connector pin No. 1. If there is continuity, replace overvoltage protection relay. If there is no continuity, repair wiring. Ensure all ABS tester switches are off.
