Son’s truck – new engine installed in Feburary, been working fine. Has a Viper alarm system on truck. ABS light has been on solid. Now when truck is started ABS begins flashing. Replaced 3 blown 15 amp fuses. Will have to verify which ones, but all light or brake related. Now I notice all lights in rear of truck stay lit as soon as the headlights are turned on. This truck also has daytime running lights (DRL). I am wondering if a ABS sensor is shorted, but don’t see anything running to rear drums even though one fuse I replaced is for rear ABS (RABS)? I am going to check the stearing column for possible wiring issues, but where do I find the ABS sensors? Are they front and rear?
