Ok, I had this 2012 Ford Escape in last month for a stalling and low idle speed complaint which was repaired by cleaning the throttle body and a relearn of idle speed. Before doing the repair I had scanned the vehicle for any relevant codes to the stalling problem. I didn't find anything related to the stalling but I'd just like to give you a walkthrough of what was there. This is an XLT with 2.5 engine and 2wd, 218,000 miles.
The ABS/Traction Control module has C1963. The C indicates a chassis code. Those are related to brake, steering or suspension systems and you should find a code in one of those systems as well. The C1963 is indicating a chassis system problem and a related or companion code should be set in the section of the chassis controls that has the problem.
In this case, the code triggering the C1963 is stored in the Power Steering Control module, B2278. B codes are body system codes. The PSCM is inside the passenger compartment.
The other codes, the U codes are related to problems with the communication between modules. The U3000-04 indicates an internal module failure in the Accessory Protocol Interface module and the U3000-09 indicates an internal module failure in the Global Positioning System module. So, even though the system wasn't part of why it was here and I didn't use it, I expect the radio or navigation systems weren't functional. Not everyone would care.
The B12B0 in the HVAC indicates an an electrical fault with the front blower relay. That would usually cause the blower to not work or to work all the time, depending on the actual condition. No mention was made of a blower problem. I'm going to assume the problem was intermittent and blower was working because you would want your blower to work in Arkansas where you can need both A/C or heat in the same day.
The B1600 is a problem with the Instrument Cluster/PATS module didn't receive a valid key signal which would cause a no-start and again no complaint concerning a no-start and it was running fine. I'll call that one intermittent.
The P1000 in the Powertrain Control Module just tells me the PCM memory has been cleared and the monitors have not had a chance to complete since that was done. What I don't know is how or why the codes were cleared. I don't know if only the PCM was cleared or if all the systems were cleared.
So while I can see some reasons for being aware of these problems, it is the B2278 that should be repaired next since it is related to your steering. The best thing about a B2278 is it doesn't involve a lot of diagnostic time to pinpoint the cause. It will need a Steering Shaft Torque Sensor. There was a time when you would have to replace the entire steering module for that but Ford has made the sensor available now as a stand alone part. Installing a new Ford sensor and the steering column mounting bolts, and a steering trim adjustment and calibration will be the fix.
Btw, most of the sensors are replaced around 200,000 miles and this has 218,000.
Thank for reading.
