ABS and VSA problem...
 

Hi guys! I'm new here. Major issue. I posted it at another forum, but might as well here. It's my Exclamation Triangle Mark and then eventually VSA light will follow. Good thing, I bought a code scanner that also can scan ABS code.

Following is what I got from my scanner.

84-01 ACURA ABS CODE:

1. IG1-2 open circuit
2. VSA Sensor neutral position not written
3. CAN Communication failure (Bus off)
4. Steering sensor input error
5. Steer angle sensor failure
6. Sensor logic failure
7. Target vehicle come closer than the multimeter radar detecting limits
8. Sensor 0 (Zero) position memorization incomplete
9. Sensor 0 (Zero) position not write.

Any ABS out there, please help! I'm completely clueless now.

As always, thanks in advance for any hints, leads, helps, etc...

how old is car battery?

Battery is about 3 years old. Still good, i think.

Anyone else has inputs? I'm pretty driving it with all the problem. Now, Check Engine Light is also on with the same code Cylinder misfired 1, 4 and 6. Replaced all those ignition coils already and swap them around, but still the same codes come back each time.

May not be the same issue, but when I bought my MDX the ABS and VSA popped on during the test drive. The dealership mentioned there was a SW upgrade to resolve the issue. It may be worth taking it in to see if this SW upgrade resolves your issue.

This was back in 2014 and haven't had any issues since.

I did a "jumpered" reset and managed to get the Triangle Exclamation Mark light off. Now, VSA no longer comes on either. So it's all good.
