HiCustomer Thank you for asking your question on JustAnswer. The other Experts and I are working on your answer. By the way, it would help us to know:
- Whats the alternator output at the battery?

Hi.
Are there other dash lights coming on? If so, I would say that your ABS module is at fault. We are seeing a lot of these fail and they knock out the serial data line.
Change-over units are available, contact your nearest Injectronics agent and they will be able to help you out.

This is really a strange problem and I haven't had this combination of codes come up before.
In just about every other case I can think of when strange things like this happen it turns out to be ABS module. I suppose it could be possible that you have an instrument cluster fault, as this has it's own control unit inside.
Other than that, I can only suggest a break in the wire that handles serial data.

Good luck, I hope you sort out your problem soon!

Matt.
