Fault code c1278, steering anle sensor - ihave allready replace steering angle sensor and EHPAS pump, Light still illuminated

SOURCE: code c1277 (steering angle sensor)

this vehicle uses a steering control module and the antilock control module. Both modules get a signal from the steering angle sensor. We found that the steering module didnot show a steering sensor code but the ABS module did show the code.
after checking that the wiring was intact and with good continuity, it was determined that the fault lies in the ABS module.
A new ABS module and configuration confirmed the diagnosis. It's fixed!
