Problem

The Fusion was involved in a front-end collision. After the body repairs, which included replacing the Steering Gear/Power Steering Control Module (PSCM), the power steering system was inoperative. The message center displayed a new warning message: “STEERING LOSS STOP SAFELY”.

Case Details

The technician connected a scan tool and found the following diagnostic trouble code (DTC): C200B:29 

• Steering Shaft Torque Sensor 1 Signal Invalid.

He attempted to download the previously saved data again from the old PSCM to the new one using the factory programmable module installation (PMI) method but could not get the system to complete the process. An ALLDATA Tech-Assist consultant suggested replacing the PSCM with another OEM part.

Confirmed Repair: The shop got another PSCM from the dealer. The technician installed it and this time the system completed the calibration process. The warning message and DTC did not return. The power steering began operating as designed. Even OEM parts can sometimes be defective right out of the box. Fixed!

If you have ever driven a car or truck with a fully locked differential around a tight corner or tried to get a car with an open differential out of a snowbank, you know about the benefits of a limited-slip differential. 

A differential allows the two connected wheels to spin at different rates. The two wheels are connected using spider gears. If the spider gears do not spin on their axis, the two axle shafts spin at the same rate. If the spider gears start to spin, the axles spin at different speeds. How the direction of the rotation changes and which axle is spinning faster determines which one gets the most power.
