Any advice you could send my way? My 2009 IS250 also has the C1241 and a C1424 both under ABS. I will load test the battery tonight and see if its a bad battery. My DRLs also flicker. But when i turn on the low beams they stop. Wondering if that's related.
Did you find out what the issue was? my 2009 IS250 also has the C1424 and C1241. Haven't load tested the battery yet, praying its just that and not the skid control ecu. Thanks
