Disconnect stoplight switch harness connector. Using a DVOM, check continuity between stoplight switch connector terminals. Continuity should exist with pedal depressed. Continuity should not exist with pedal released. If continuity is not as specified, check STOP fuse and wiring harness. Check wiring harness between stoplight switch and ABS control unit. Repair or replace if necessary. If fuse and wiring harness are okay, replace switch.
