TCS codes: u1073, u1262, C1805, B2900;
When I come to a complete stop stop light, when I go to accelerate, the car doesn't move, although the RPM hand is bouncing up and down. Sometimes, the car does move, but no faster than 20 mph. Sometimes I have to turn the car off for several minutes in order to drive. Is this an ABS issue? Or, wheel speed sensor issue? The problem is very intermittent. I've taken it to a transmission shop, who thinks its a ground/wiring problem.

Did you change any modules on the vehicle ?The anti-lock brake system (ABS) module or stability assist module (if equipped) does not respond to the diagnostic tool - Circuit or connection in the standard corporate protocol (SCP) network.
- ABS module.
the standard corporate protocol (SCP) communications network the international standards organization (ISO) 9141 communications network the universal asynchronous receiver-transmitter (UART) based protocol (UBP) communications network The diagnostic tool connects to all 3 networks through the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one diagnostic tester to be able to diagnose and control any module on the 3 networks from one connector. The DLC can be found under the instrument panel between the steering column and the radio.
B2900 VIN Mismatched ABS Module VERIFY that the module has the correct as-built >
- Go To Pinpoint Test A .
U1123 Invalid or Missing >The SCP communications network will remain operational even with the severing of one of the bus wires. Communications will also continue if one of the bus wires is shorted to ground or voltage, or if some but not all termination resistors are lost. The SCP communications network allows inter-module communication.
The ISO 9141 communications network does not permit intermodule communication. When the diagnostic tool communicates to modules on the ISO 9141 communication network, the diagnostic tool must request all information, or initiate module commands.
The ISO 9141 communications network will not function if the wire is shorted to ground or battery voltage. Also, if one of the modules on the ISO 9141 communications network loses power or shorts internally, communications to that module will fail.
The UBP communications network will not function if the wire is shorted to ground or voltage. The UBP is different from the ISO communication network in that it allows intermodule communication.
I have Ford / Lincoln service info on my lap top ,The first thing to do is VERIFY that the module has the correct as-built style="display:none;">I have Ford / Lincoln service info on my lap top ,The first thing to do is VERIFY that the module has the correct as-built data. an correct VIN number in both the PCM an ABS modules ! That's where there IDS scan tool comes into play ! They probably won't be able to extract that info out of those two modules ,but not to worry they can go on the motorcraft web site an find that data !
I wish you lived in my area!!!! I will touch base with you after my appointment. It appears that the people who CAN help me are too far away, and the one's who have NO INTEREST or idea on how to help me are within reach. You gave me hope!!!! The last shop said mt problems were related to the mismatch VIN issue, and there were no solutions; however, after much research, there are possible solutions. Mind you, I've been spending money chasing this problem for over a yr now.
