Here is a picture of the code reader with lights lit up in red, just so there's no confusion....I'm wondering if this is related to my problem or not, or if this is happening where car was reset, even though i have driven it

 

[wjarms]

What about what i do know?? the ABS code C056D-00, can anyone relate to this, is this normally caused by loss of vacuum, lost communication, and if so what pins are loosing connection that I've seen others talking about?? I just need help fixing this issue, It cant be this difficult or shouldn't be at least ?? and i cant understand the red lights on the innova with no engine lights either

Ok i can accept the voltage variations, but why the increased ohm load with key on???

Generally, you can't measure ohms in a live circuit. The ohm meter can't tell the difference between the voltage drop it's creating and the one caused by the live circuit.

As for the monitor, double-check the manual, but I believe that's in indication that those tests ("monitors") haven't been run yet. So they have neither passed nor failed. Some tests require specific conditions. A trip around the block isn't likely to create them.

Wow. When did Innova go color? Anyway, from the user manual (emphasis added)l:

Monitor icons - Indicate which Monitors are supported by the vehicle under test, and whether or not the associated Monitor has run its diagnostic testing (Monitor status). When a Monitor icon is solid, it indicates that the associated Monitor has completed its diagnostic testing. When a Monitor icon is flashing, it indicates that the vehicle supports the associated Monitor, but the Monitor has not yet run its diagnostic testing.

You're going to have to drive it some more to get those monitors (tests) done. You might want to google around and see if there's something speicfic it's looking for. It might need a long coast downhill or a long drive uphill.

Just found this for C056D

http://sandyblogs.com/techlink/wp-content/uploads/2013/01/January-Techlink-2013-F.pdf

Not specific to the Cruze but GM reuses the same codes for the same purposes across model lines.

 

[wjarms]

So it's pointing to the multi axis sensor..which is called the Yaw Rate Sensor in the Cruze... But now I can't find a picture or anything showing its location so that I can check it.... I do know my dash has been apart before I got the car though.. And quick question, does warranty discontinue if a vehicle is rebuilt? But yeah location of this sensor would be nice lol

 

[ChevyGuy]

I tried looking up the code. Not a lot of information - just "internally detected error". It did suggest that if raised by a programmable module, that it should be re-programmed. So maybe the best thing is just to let the dealer connect up to it and go over all the programming. Something might have gotten replaced and the car's not too happy about it.

The Yaw Sensor is in the console, straddling the center line of the car, between the gear shift and the emergency brake. The book indicates it has to be re-programmed if replaced. That requires an appropriate scan tool. I'm not sure if a 3rd party one can do that.

 

[wjarms]

OK I'm going to take console out later to make sure it's not damaged from any impact or even missing

 

[wjarms]

Wonder if when I take it in for the ecu to be reprogrammed if they would go ahead and do that for free since they're doing computer work anyhow or if it reprograms everything at once?

Here is the flow chart for this code. Whenever you have a hardware fault code set in a module the module needs to be replaced as the internal parts of the ebcm are damaged, not the software part. Also the battery cable recall will not set this code. I also did not know the year of your vehicle but doesn't really matter what year it is this code means the same for all years.

DTC C056D
Diagnostic Instructions

• Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure.
• Review Strategy Based Diagnosis for an overview of the diagnostic approach.
• Diagnostic Procedure Instructions provides an overview of each diagnostic category.

DTC Descriptor DTC C056D Electronic Control Unit Hardware
For symptom byte information, refer to Symptom Byte List.
Circuit/System Description The internal fault detection is handled inside the device. The symptom byte information is for engineering reference only. No external circuit diagnosis is involved.
Conditions for Running the DTC The device runs the program to detect an internal fault when power up is commanded. The only requirements are voltage and ground. This program runs even if the voltage is out of the valid operating range.
Conditions for Setting the DTC The device has detected an internal malfunction.
Action Taken When the DTC Sets The device refuses all additional inputs.
Conditions for Clearing the DTC

• A current DTC clears when the malfunction is no longer present.
• A history DTC clears when the device ignition cycle counter reaches the reset threshold of 50, without a repeat of the malfunction.

Diagnostic Aids

• This DTC may be stored as a history DTC without affecting the operation of the device.
• If stored only as a history DTC and not retrieved as a current DTC, do not replace the device.
• If this DTC is retrieved as both a current and history DTC, replace the device that set the DTC.

Circuit/System Verification

• Ignition ON.
• Verify DTC C056D is not set.
  • If DTC C056D is set Replace the device that set the DTC.
  • If DTC C056D is not set
• All OK

Repair Instructions Perform the Diagnostic Repair Verification after completing the repair.

Can I ask where you get this service information and access to all the links contained therein?

@wjarms Did you ever resolve the StabiliTrak issues? I realize this is now 8 years(!) later...

Those links seem to be from a GM website and may not work anymore. Both the poster of those links and the OP have not been online here since 2015

Hi,do you manage to solve the issue?

Hi,do you manage to solve the issue?

Welcome Aboard!

Don't forget to introduce yourself and your Cruze here.

The original poster has not been online here since 2015.

This code has something to do with the steering angle sensor (SAS), which I believe is located within the steering wheel setup.

Attached is a related PIP - different GM vehicle, but same issue.
