    I have the old rear-wheel anti-lock braking system and I have been getting a solid brake light for about a week. Yesterday I checked the codes on the RWAL controller and it kept blinking 4 or 44, definitely 4... I'm not quite sure what that means... I cleared the code but haven't driven the truck any to see if it will come back. Any wisdom to offer?

    Ok, drove it around for a week and a few days here and there and no code. Then, I go through a drive through today, and it came back on. I think I found my issue that causes it. When I sit in the drive-thru line, I get bored and so I creep up on people's rears and sit there. To make sure I dont move, I put the truck in neutral and push hard on the brake pedal, using one foot to apply even more pressure to the first foot. I think I'm pushing the brake pedal down so hard at that time that some sensor in the brake system goes out of its acceptable range and throws the code. It's the only link/commonality I can find that would explain this...
