Chevy 3500 van: We have a 2011 chevy 3500 van with a 6.6 diesel

Customer Question

We have a 2011 chevy 3500 van with a 6.6 diesel engine. Upon start up we have a stability control code. The code is C0710. Steering angle code. We changed the front end steering parts and aligned the vehicle prior to setting this code. The code was not present before.

Hi,Did you try clearing the code to see if it would return?
Customer: replied 1 year ago.

Yes, its an active code.

Expert:  Daniel Jones replied 1 year ago.
What kind of repairs did you do to front end?
Customer: replied 1 year ago.

Tie rod ends. Also had to remove the gear box to gain access to the pitman arm. Is there a recalibration for the steering sensor?

Expert:  Daniel Jones replied 1 year ago.
They had a problem with these sensors, with terminal contact and a bulletin #PI0639B: Service StabiliTrak Message Displayed in DIC, StabiliTrak Indicator Light On, DTC C0455 and/or C0710 Set - (May 23, 2013)Models: 2007-2013 Cadillac Escalade Models2007-2013 Chevrolet Avalanche, Colorado, Silverado, Suburban, Tahoe2008-2013 Chevrolet Express2007-2013 GMC Canyon, Sierra, Yukon Models2008-2013 GMC SavanaAll Built Prior to October 01, 2012To correct a fretting condition disconnect the suspect connector and add Nyogel lubricant 760G (dielectric grease) to both sides of the connector terminals. Then reconnect the connector and wipe away any excess lubricant. This will correct the additional terminal contact resistance due to the terminal fretting corrosion. My past experience with this code usually required replacing the sensor.
Expert:  Daniel Jones replied 1 year ago.
Sometimes if you unplug sensor and plug it back in again it might clear the code temporarily.

are you getting my replies?????

Expert:  Daniel Jones replied 1 year ago.
I got the reply on what parts you changed.
Customer: replied 1 year ago.

ok not your fault. Here is what you missed. When turning right we see 5 volts to a point, the it drops off to 0 at full right turn. turning left we see .2 volts at full left turn. Is there a reprogram for the sensor. we didn't have any codes prior to the steering parts change.

Expert:  Daniel Jones replied 1 year ago.
There is no reprogram.
5v is normal.
Here is how the system operates.
The electronic brake control module (EBCM) supplies a 5 V reference and provides a low reference to the steering wheel angle sensor. The EBCM monitors the signal circuit and the three phase circuits to determine the steering wheel position. The EBCM receives three signal inputs from the steering wheel speed/position sensor. The Index Pulse signal is only High when the steering wheel is centered or within a few degrees of the straight ahead position. The 2 input signals Phase A and Phase B are approximately 90 degrees out of phase. The EBCM dynamically interprets the relationship between the Phase A and Phase B inputs, and determines the position of the steering wheel and the direction of the steering wheel rotation.

Are you looking for a second opinion on this question?
Customer: replied 1 year ago.

yes I am

Expert:  Jerry Newton replied 1 year ago.
OK, just wanted to verify that before jumping in here. There is a suffix that comes after the code, if you have a scan tool capable of that. Do you know what the suffix is? It would look like C0710 5A or something similar to that. The suffix tells us precisely what the nature of the failure is, and can be very helpful with diagnosis.
Customer: replied 1 year ago.

There is no suffix. What is does say is. Steering angle sensor circuit signal/ waveform failure (system 17). current DTC. test failed. test not passed since power up.

Here is the
Circuit/System Testing
Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the steering wheel speed/position sensor. It may take up to 2 minutes for all vehicle systems to power down.
Test for less than 20 Ω between the low reference circuit terminal 2 and ground.
If 20 Ω or greater
Ignition Off, disconnect the harness connector at the EBCM.
Test for less than 2 Ω in the low reference circuit end to end.
If 2 Ω or greater, repair the open/high resistance in the circuit.
If less than 2 Ω, replace the EBCM.
If less than 20 Ω
Ignition ON.
Test for 4.8–5.2 V between the 5 V reference circuit terminal 1 and ground.
If less than 4.8 V
Ignition OFF, disconnect the harness connector at the EBCM.
Test for infinite resistance between the 5 V reference circuit and ground.
If less than infinite resistance, repair the short to ground on the circuit.
If infinite resistance

If less than 2 Ω, replace the EBCM.
If greater than 5.2 V
Ignition OFF, disconnect the harness connector at the EBCM, ignition ON.
Test for less than 1 V between the 5 V reference circuit terminal 1 and ground
If 1 V or greater, repair the short to voltage on the circuit.
If less than 1 V, replace the EBCM.
If between 4.8–5.2 V

ok. we're checking it. give me a little time.

Expert:  Daniel Jones replied 1 year ago.
The Service bulletin tells you to put a piece of something on connector to make it tighter. But from my experience with this code it hasn't worked. I always wind up changing the sensor.
This is what bulletin states:
Add a piece of Adhesive Back Shim Stock the width of the connector to the flat surface on the male connector. This provides support to the connector to keep it from moving up and down.
Important: DO NOT apply an excessive amount of dielectric lubricant to the connector, as hydrolock may result when attempting to mate the connector. Use ONLY a clean nylon brush that is dedicated to the repair of this specific condition.
3. With a nylon bristle brush, apply dielectric lubricant to both the sensor side and the harness side of the affected connector.
4. Reconnect the steering wheel position sensor connector and wipe away any excess lubricant that may be present.
