SOURCE: LINCOLN CODE READ ON SNAP-ON SCANNER. U1262

bottom line is the U1262 is a communication failure between your scanner and a module

assuming you actually pulled the code from the PCM then you have lost communication with a different module like the ABS, DDM, LCM, RASM, HEC, PAM and any other module I can't think of right now

You need a detailed pinpoint test from a Ford service manual or aftermarket source like Alldata, Shop key or Mitchell on Demand

You could be dealing with over a 100 different test PER module

Obviously something we can't do on-line too easily

If you could at least identify which module you have lost communications with your dealer may, for a fee, copy the correct pinpoint test

What are the meaning of the codes on my diagnostic unit for my ford Freestar?


U1059 - SCP (J1850) Invalid or Missing Data for Transmission / Transaxle / PRNDL
U1027 - SCP (J1850) Invalid or Missing Data for Engine RPM
U1009 - SCP (J1850) Invalid or Missing Data for Engine Torque
These are communication codes from one computer to another. I would have to see it on a scanner. But, since your transmission computer and engine computer are in the same housing, it is most likely an internal problem.

I have multiple codes instrument cluster codes: u1073, u1262, u1059, u1123, u1041; ABS/TCS codes: u1073, u1262, C1805, B2900;


Did you change any modules on the vehicle ?
B2900 VIN Mismatched ABS Module VERIFY that the module has the correct as-built data.
CHECK for correct powertrain control module (PCM) and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the C1805 Mismatched PCM and/or ABS/TC Module ABS Module CHECK for correct PCM and ABS module configuration using the diagnostic tool. RECONFIGURE the component as necessary. FOLLOW the diagnostic tool directions for the ABS module configuration or REFER to Section 303-01A or Section 303-01B for the PCM. CLEAR the DTC. REPEAT the self-test. U1073 SCP (J1850) Invalid or Missing Data for Engine Coolant PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1262 SCP (J1850) Communication Bus Fault Network Fault REFER to Section 418-00 . Can a scan tool communicate with all the 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.
  • Go To Pinpoint Test A .
U1123 Invalid or Missing Data For Odometer Instrument Cluster Go To Pinpoint Test G . U1059 SCP (J1850) Invalid or Missing Data for Transmission/Transaxle/PRNDL PCM REFER to Powertrain Control/Emissions Diagnosis (PC/ED) manual. U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Instrument Cluster REFER to Section 413-01 . U1041 SCP (J1850) Invalid Or Missing Data For Vehicle Speed Tire Pressure Monitoring System Module REFER to Section 204-04 . You need to take it to the dealer , not a transmission shop. Your vehicle could have a ground issue , could have power issue , could have a control module issue . It needs to be hooked up to the factory scan tool ! It is for sure it has a communication problem on the SCP data bus , do you know what serial data communication is ?
The vehicle has 3 module communication networks:
  • 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.
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.
