I got SDD up and running, but it's not the most user-friendly program and I'm confused about something. I'm getting a U0437-68. When I look that up in the service manual it says this:



So how do I check a specific module for stored DTCs in SDD?

 

Sam, it's referring to the DTC index in the service manual. For your issue, I think page 350

Download it here:

You'll want to run a diagnostic scan and check against the DTC's on that page. That's my take on it anyway.

 

But how do I check the differential control module for stored DTCs? The code that SDD is giving me is more of a generic code.

 

Send me an email, I'll give you some instructions.

 

Are we just talking about selecting symptoms here? What was the outcome of this?

 

Thank you, Cambo! Your instructions were a big help! I forget the exact DTC #, but the description said something like "differential motor stuck". I'm paraphrasing, but it definitely used the word "stuck".

So... I guess the problem is the motor itself. I've been under the car to look at it. It looks like I might need to drop the whole rear end to get to the bolts on the top side of the differential motor.

 

Can you kindly share how you get the stored DTC with SDD ?

Thanks
