Morris,

This is an old post. If you are still having problems, verify you have positive and negative going to the controller. Is this the only code you have on the truck? If so then there is either a failed connection or controller. At the steer column, the service connector has three wire connection. The top left is A, right is B and bottom is C. Check resistance between A and B. Should read either 60 or 40 ohms with battery disconnected. Should you read half, 120 or 80, you have a failed resistor. Also check between A and C and B and C. They should read 0 ohms. Any other reading shows a short in the CANBUS system. Using C as negative, battery connected and switch turned on, check voltage at A and B. Should read about 2 to 2.5 volts each. Make sure all connections at the controller are good and tight. Good Luck.
