Need your help. I wonder if anyone experienced similar or could provide possible root causes for me ( a DIY , 3-4 degree ) to fix. Are these code related? where should I look into? C1241: "ABS Hydraulic Pressure Differential Switch Input Short Circuit To Ground" C1407: "Traction Control Valve Rear Circuit Short To Battery" C1408: ? my Corolla has154040 miles, in the past 4 or 5 years, once a while , the VSC OFF light will come on when passing a puddle (but not every time especially if it's not in acceleration.) it will go off after few days or couple of weeks. This time it happened with P0138,? Not sure if they are related (hot line short?) Please help, all clues are welcome. Thank you.
Ref. per "C1241 Code, 2010, Highlander" link, so, I got two questions: 1. per carponets, C1241 is "ABS Hydraulic Pressure Differential Switch Input Short Circuit To Ground" 2. I checked my battery is old "12/16", however voltage is ok 12.30V.
