Hello, I picked up a new to me 2006 frontier SE 4x4 164000 kms (101900 miles) I bought it off a couple living on a acerage and they said it's been sitting for 4 years. I literally only paid $100. The truck had a few problems though when I drove it. I replaced the whole timing chain assembly and a new water pump because it had a terrible winding noise but it's good now. I changed all 4 brake pads and flushed all fluids. My ABS and SLIP light are on, also the Service engine soon. I am wondering if these light will cause my 4x4 not work? Id like to get it wok because it's the first snowfall here in northern Alberta.
