Hi, I am new here. I have 2006 model, 90k miles, second aux battery, and was converted to plug-in last year. The (!), ABS and VSC warning lights ON are random, most during the startup. The car seemed function fine. I am going to check the relays like Patrick said later and report here. In order to find code for above problem, I borrowed OBD reader from local auto parts store. The OBD meter couldn't read the code for that problem, but found P1121, which is coolant flow valve jamming. I have my two water pumps replace last year (one was under warranty). The check engine light was never on. I tried to reset the code by the OBD meter, but no success! Do I need to replace the valve, or it is a faise code?
