Hello people I'm new. Just picked up a 2006 with the 2.4L. My 4x4 light is on but there are no engine codes. I did notice one of the rear axle seals is leaking, but I topped up the diff fluid. Light is still on. The front is also leaking a tiny bit. Would the light be on because of that or is there other things I should check out? Everything else on the Rav seems to be gtg. Any help on what to look for or do would be great. Thanks!
