Hicas Diagnostic Code Youtube Videos

[hks33]

Hey all,

Could anyone please shed some light on what the error code is I'm getting for my Hicas as I'm having a little bit of trouble figuring out on what it may be, Rear end of the car is dangerously swaying from left to right over small bumps and dips in the road along with the back end jumping/skipping over the road when cornering.

Would really like this problem solved and not to take the easy way out by putting a lock bar in. Below are 2 videos i have recorded of the diagnostic fault code.

Best regards and looking forward to your responses Chris.

Do you thnik you could give some notes as to what/when the start of the sequence is, when it starts to repeat, etc?

Best regards Chris.

Yeah, nah, I meant at what point in your video is the start of the sequence and the point where it starts to repeat. Just makes it easier to suss it out, without having to work so hard.

Mode B)

Lamp on for 5 seconds.

No pulses for 5 seconds.

Nine 2-second interval indicating the system status (18 seconds total).

(short (0.1 sec) pulse = good, 1 second pulse=bad)

Well, it looks like the two codes are 22 and 23, which indicate that your steering angle sensor has either died, or you have replaced the steering wheel with one that does not drive the sensor properly ( a common rookie mistake).

Just FYI, the correct answer to the information I asked for was..... Sequence starts at the beginning of the video. Error codes start at 7 seconds. Sequence starts repeating at 24 seconds.

This may be helpful for future checks?

Steering wheel is oem could be thinking it wasn't aligned properly... Knew one of the codes was code 23 but thought the other was code 12.

First flashes in the sequence are two long two short. 22.

Steering sensor is quite possibly dead.

[hks33]

First 2 flashes indicate mode "a" or mode "b" I'm fairly confident. Then the sequence starts from there with 1 slow flash and 2 fast flashes, Then 2 slow flashes and 3 fast flashes which is what my understanding is. I could be wrong but as i said this post is just for clarification

I know the steering sensor is one of the fault codes confidently.
