Default 4ws error code 20 on 5th gen

hey guys. i have a situation but its hard to find the manuals because all the topics are 15 years old



today i wanted to start my 98 lude’s 4ws. which has 60 error code earlier. i changed with a used one of the rear actuator for the error and then i got a 63 error. . i changed the main 4ws ecu and reset the 4ws. no errors. yieeyy! it was workin on lift. however, when it gaves a error code 20 on the ground. i reset it 2-3 times. nothing changed. when i checked the error code it says main steering angle sensor (front). but i don’t know how to fix it. i think i need a service manual for it. because in some topics, you guys said it has to be centering. how can i do it? where can i do it? where is that sensor?



also i checked all the wirings. they all works.



could you please help me about it. thanks.

Hey man, fellow Lude fan here. It sounds like you have a clock spring issue. I believe your front steering angle sensor is part of or behind the airbag clock spring. All of this is behind your steering wheel. Does your horn work?
Also I have some workshop manuals. I can post a link. Let me find the file.....

You are correct. I figured you didn't have a USDM with a 4ws swap. Your issue however seems to be the SAS behind your steering wheel. The repair will be the same for JDM and USDM. Your code comes back to the clockspring.

The connector for the SAS should be behind the wiper switch. Maybe its loose? Do you have a scan tool that will calibrate it for you? I see you rest the control module but sometimes you have to do weird stuff to recalibrate them, like drive in circles at 20mph for 4 turns then same thing the other way, then throw up, cycle the igniton haha.

Good luck man! You'll get it I'm sure. Those systems can be tricky, even the normal 2ws ABS/TRAC/VSA systems are difficult to diagnose at times.
